Count birds in your backyard or community for science – and fun!

A popular way to view birds this month is to participate in the 114th annual Audubon Christmas Bird Count (CBC) with one of Washington’s 46 official counts scheduled between Dec. 14 and Jan. 5, 2014.

The longest running citizen science survey in the world, the CBC provides critical data on bird population trends. Tens of thousands of participants throughout the Americas know that it’s also a lot of fun.

The count has become a family tradition among generations, with veteran and novice birdwatchers armed with binoculars, bird guides, and checklists, often out before dawn and until dusk, on an annual mission to both make a difference and to experience the beauty of nature during the holiday season.

If you’re just learning bird identification, joining up with others who are more knowledgeable is one of the best ways to accelerate your education. If you’re a pro at distinguishing Cassin’s finches from house finches or sharp-shinned hawks from Cooper’s hawks, join a count to help others.

All of the official counts are within designated areas, and long-running ones have traditional spots within those areas to look for birds. But many counts also include what you might tally the day of the count at your own backyard bird feeder.

Contact the coordinators listed here by area and count dates to find out how you can get in on the holiday fun.

Watch winter waterfowl wisely

Fall and winter are great times to watch waterfowl at many sites close enough to home to make for fun family holiday field trips.

Ducks, geese, swans and other waterbirds concentrate in many locations where big open water provides security and adjacent wetlands and fields provide food -- both for resident birds and those making a migration stopover.

The sheer numbers of these bigger, colorful birds makes viewing relatively easy and they’re a great species group to learn identification skills. Whether on water or foraging in fields, waterfowl are relatively stationary, so you’ll have longer viewing time. Many species of ducks have exceptional markings that make identification easier, at least compared to songbirds. Just be sure to take along a good field identification book.

As with all wildlife, waterfowl watchers need to be respectful. Even from viewing platforms and boardwalks at parks and refuges, remember that you are in their home. If you get too close or make too much noise, you might disturb the birds and lose your opportunity to watch them if they flush.

To watch winter waterfowl wisely, follow these tips:

  • Use binoculars or scopes to keep your distance but still watch closely
  • Use telephoto lenses on cameras to get that great shot without getting too close
  • Move quietly, slowly, and in plain view
  • Use a viewing blind if one has been provided
  • Avoid use of calls, tape recordings of calls, or other devices
  • Divide large groups of people into small groups to be less disturbing
  • Don’t try to feed ducks and geese and don’t leave litter that they might mistake for food

Respect the property of others by viewing waterfowl on public land whenever possible. In Washington it is your responsibility to know if you are on private property. (Private property does not need to be posted or fenced.) If it is necessary to cross private property, always ask permission of the landowners before doing so.

Washington has a wealth of spots where fall and winter waterfowl viewing is exceptional. All seven of the Great Washington State Birding Trail maps -- sponsored by Audubon Washington, Washington Department of Fish and Wildlife (WDFW), and others -- include fall/winter waterfowl watching locations. Seattle Audubon has a wealth of birdwatching information regarding sites and seasonality of species occurrence at their BirdWeb site.

The following are among the best fall/winter waterfowl viewing spots, based in part on accessibility and proximity to population centers. They include some of WDFW’s mid-winter waterfowl inventory survey “priority one” areas with traditional high concentrations of waterfowl at this time of year, and some of the reserves that are closed to waterfowl hunting.

Fall is deer collision time on our roadways in Washington for a number of reasons.
Fall is deer collision time on our roadways in Washington for a number of reasons.

Watch out for deer on the roads this fall

If only it were this easy……

Did you hear about the folks who called the Department of Transportation to request removal of the “Deer Crossing” sign on their road? They said that too many deer were being hit by cars and they no longer wanted them to cross there.

Fall is deer collision time on our roadways in Washington for a number of reasons.

Some are about deer behavior at this time of year. Deer generally move to lower elevations in the fall for easier foraging, and that’s often near human development, including roads. It’s also the rut or breeding season for deer, when bucks are less wary and all deer are moving around more.

Some are about our behavior at this time of year. Shorter days and the shift to daylight savings time put more drivers out on the roads during dimly lit hours when everything is harder to see.

Whatever the reason, the increased collision rate with deer in the fall was long ago documented by a Washington Department of Fish and Wildlife (WDFW) analysis of a Washington Department of Transportation (WSDOT) database on deer and elk carcass removal on roadways across the state. Between 2000 and 2004, a total of 14,969 deer and 415 elk carcasses were collected and recorded by date and specific milepost on Washington’s 7,046 miles of highways that receive 31.6 billion miles of travel each year.

The data confirmed some intuitive notions -- deer-vehicle collisions are greatest where deer populations are most dense and where traffic is greatest. Because of those factors and others, high collision sites are clustered, not random, and WSDOT posts deer crossing signs accordingly.

The highest number of deer collisions occur during the fall and highest number of elk collisions occur during the winter. The data also confirmed:

  • The majority of sites with unusually high deer-vehicle collisions were associated with posted speed limits of greater than 50 miles per hour.
  • Somewhat lower collision counts were recorded on roads with more curves and vice-versa (straighter roads were associated with higher collision counts.)
  • Lower collision counts were observed on eastern Washington rural interstate highways, eastern Washington urban principal arterials, and western Washington urban minor arterials –at least compared to other roadway classifications.

Comparing the WSDOT data with established landscape databases revealed a few more patterns, including:

  • Cover, forage, and water available near roads were generally associated with higher collision counts in eastern Washington mule and white-tailed deer habitat.
  • Southern aspects (south-facing roadside slopes) were generally associated with higher collision counts in western Washington rural areas.
  • Lower collision counts were associated more with steep roadside slopes (more than 35 degrees) than with moderate slopes (less than 35 degrees).

So what can be done to avoid crossing paths with deer in such a traumatic way?

For the driver, slowing down during fall and winter is the first step, especially in the hours just before, during, and after dusk and dawn. Paying attention to WSDOT’s deer crossing signs, and particularly “high kill area” signs, can be critical. Speed limit reductions at night along stretches of highway with a high rate of collisions might be in order.

In general, new highway development in high deer or elk use areas should be avoided.

Deer or elk could be protected from collisions with construction of fences along roadways with high collision rates, especially if combined with existing bridges or development of over or under passes to allow natural movement. Such efforts have proved effective in other parts of the country.

Washington WSDOT has wildlife crossing projects underway, such as the Snoqualmie Pass East section of Interstate 90 which will have three miles of the five-mile project completed by the end of this month. (For more information see www.wsdot.wa.gov/Projects/I90/SnoqualmiePassEast/HyaktoKeechelusDam/).

Not all collisions with wildlife become roadkill. If you hit and injure a deer or other wild animal, or find an injured wild animal on the roadside, you can call a trained wildlife rehabilitator who might be able to safely retrieve the animal and care for it.

Are your birds southbound, just arriving, or homebodies?

House wren
House wren

Many of us backyard birdwatchers are witnessing the change of the seasons this month, with hummingbirds no longer visiting our flowers or nectar feeders and large groupings of other birds moving out.

But is it just goodbye to migrants and a familiar nod to year-round residents? 

Is that chickadee you’ve been watching flit in and out of a nestbox all summer the same one you’ll see at your winter feeder a few months down the road? When you look at that “year-round range” map stretching from Alaska to the southwest U.S. in your field guide, do you wonder if your summertime chickadee is beating wings to New Mexico for the winter, and the ones you see this fall just moved in from British Columbia?

Are your backyard birds heading south, just arriving from parts north, or are they homebodies hanging out 24-7-365?

Chances are, it’s a little bit of all three, depending on the species using your backyard wildlife habitat.

As experts at the Cornell Lab of Ornithology say, migratory patterns vary by species and sometimes within the same species.

Short distance migrants often include species that are permanent residents in most of their range, but with migratory tendencies on the edges or in pockets of their range.

Hairy woodpeckers are primarily non-migratory, permanent residents throughout their breeding range. However, northernmost populations display irregular and unpredictable wandering in winter. Local post-nesting short-distance movements take place in some areas. In some situations individuals breeding at higher altitudes seem to disperse to lower altitudes during non-breeding season or from inland to coastal locations.

This may be the migrating pattern category that fits one of our most common backyard winter feeding station visitors – the black-capped chickadee.

Medium distance migrants tend to exhibit a variety of irregular patterns of north/south migration but remain in North America.

Jays in general tend to fit this pattern, although much remains a mystery. Here in the Pacific Northwest, some Steller’s jays are present throughout the winter in all parts of the range. Young jays may be more likely to migrate than adults. Some individual jays may migrate south in one year, stay north the next winter, and then migrate south again the next year. Many who feed birds in their backyard may be seeing one population of jays in the winter and an entirely different population of jays in the summer.

The northernmost breeding population of white-crowned sparrows migrates from Alaska and the Yukon to the southern plains of the United States and into northern Mexico. A different subspecies breeds farther south, ranging from British Columbia to northern California. These white-crowns migrate a shorter distance to the lowlands of central and southern California. A third subspecies is a permanent resident in parts of coastal California.

Killdeer are classified as medium-distance partial migrants, another way of saying their movements are complex and poorly understood. Banding records suggest general southward fall migration in North American birds, with no strong directional orientation. Some killdeer migrate through western North America and Central America while others winter in the coastal and wetland areas of California.

Some wrens, red-winged blackbirds, house finches, goldfinches, juncos and evening grosbeaks may fit this category, too, breeding in Canada or here in Washington, and some wintering here or in Oregon, California, and other southwest states or Mexico.

And then there are the really mysterious movers – red crossbills and pine siskins, whose ranges are described in many field guides as highly irregular, irruptive, erratic or wandering, probably due to fluctuations in food sources.

Long distance migrants undertake migratory journeys that can take weeks to complete and cover thousands of miles. Some 350 species are considered “neotropical” migrants, from "neo" referring to new and the new world of the Americas, and “tropical” defined as the latitudinal region between the Tropic of Cancer in the northern hemisphere and the Tropic of Capricorn in the southern hemisphere.

These birds breed in the United States and Canada and winter in the Caribbean, Mexico, Central America and South America. Neotropical migrants include raptors, vultures, waterfowl, shorebirds, and passerine (perching songbird) species such as hummingbirds, thrushes, warblers, orioles, and tanagers.

Some species do not migrate at all because they are able to find adequate supplies of food throughout the winter in the same place they breed and rear young. Crows, quail and pheasants definitely fall into this category. Some owls and nuthatches might also be permanent residents.

Songbird Journeys - Four Seasons in the Lives of Migratory Birds,” a book by Miyoko Chu, science writer at the Cornell Lab of Ornithology, delves into more detail on bird migration. The following is from a Lab description of the book:

“One of the world’s most extraordinary wildlife migrations passes unseen within hundreds of feet of our own neighborhood--the night flights of millions of songbirds. By dawn, these colorful migrants descend to our backyards, urban parks, and forests, either to replenish themselves for the rest of their trip or to settle in for the summer and raise their young.

Until recently, little was known about the lives of songbirds during their travels from autumn until spring. Aided by modern technology, however, scientists have documented mass migrations over the Gulf of Mexico, identified the voices of migrants in the night sky, and showed how songbirds navigate using stars, polarized light, and magnetic fields.

Miyoko Chu explores the intricacies underlying the ebb and flow of migration, the cycle of seasons, and the interconnectedness between distant places. “Songbird Journeys” pays homage to the wonder and beauty of songbirds while revealing the remarkable lives of migratory birds and the scientific quest to answer age-old questions about where songbirds go, how they get there, and what they do in the far-flung places they inhabit throughout the year.”

Deer in the summer roses

August 2013

Is your last rose of summer going to the deer?

August is the time to enjoy the fruits of your gardening labors, from tomatoes on the vine to those last roses of summer on the bush.

But are deer thwarting your plans for backyard garden gratification?

Those lovely, graceful, peaceful creatures can frustrate even the most benevolent, wildlife-appreciative gardener, especially when there’s a small herd helping themselves. And as natural forage is drying out with late summer heat, irrigated landscapes and gardens become more attractive to more deer.

Deer repellents, commercially available or homemade, can be a good short term solution. They work best if applied before deer develop a routine feeding pattern, so you actually should have been using them two months ago to prevent a habit from forming, instead of trying to break one now. Most repellents have to be re-applied after rain or watering.  And they work because they have a disagreeable odor and/or taste – disagreeable not only to deer, but also to you!

Like most animals, deer are neophobic (fearful of novel or new-on-the-landscape objects), so things like barking dogs, scarecrows, bright lights, radios, whistles and other noisemakers can work – for a while. Deer soon get accustomed to these things and damage resumes after they realize no actual harm will come to them.

The best insurance against deer (or elk) damage is a high (six to eight feet) woven-wire fence. That may be the ticket for a vegetable garden, or around individual young trees or shrubs. But fencing may not be practical nor aesthetically acceptable around an entire landscape.

Landscaping with deer-resistant plants may be your best alternative to fencing.

There is no such thing as a completely deer-proof plant in every situation with every deer. Whether or not a plant will be eaten depends on several factors: the deer’s nutritional needs, its previous feeding experience, plant palatability, time of year, and availability of wild foods. When preferred foods are scarce, there are few plants that some deer will not at least try to eat. A large deer population can create competition for food, causing deer to eat many plants that they normally would avoid. A walk or drive through your neighborhood can give you an idea of what plants are being eaten or avoided by deer. 

In most areas, deer love roses, willows, clover, dandelions, and many kinds of berry-producing plants. A list of food plants used by Pacific Northwest deer is available at http://wdfw.wa.gov/living/deer.html#food.

Deer tend to avoid established (not necessarily young new growth) irises, daylilies, daffodils, sedums, poppies, lilacs, lavender and many herbs. A list of deer-resistant plants is available at http://wdfw.wa.gov/living/deer.html#landscaping.

If you don’t want your last rose of summer going to the deer, and are ready to use more deer-resistant plants, just keep in mind that anything you add now to a landscape already suffering from severe deer damage, will likely also be browsed – at least initially.

Let us know what works – or not – for you, and we’ll share more tips with your fellow wildlife-loving gardeners in future editions. (E-mail Crossing Paths editor at Madonna.luers@dfw.wa.gov .)

Birdwatching across the state.
Pale swallowtail

From backyards to mountain tops,butterfly watching peaks this month

Whether you’re relaxing in your own yard full of blooms, or hiking in meadows or mountains for a retreat from urbanism or just to beat the summertime heat, this is the month to watch for butterflies.

Wildflower blooming peaks in July and that means the greatest diversity of adult butterflies are feeding on the nectar of those blooms.

Washington has an incredible diversity of butterfly species – 158 total statewide according to the “Life Histories of Cascadia Butterflies” (Oregon State University Press, 2011). Newcomers to butterfly watching quickly learn there’s much more than big yellow swallowtails flying around. From commas, checkerspots and blues, to sulphurs, tortoiseshells and whites, the range of size and color of local butterflies is spectacular.

The variety of flowering plants that butterflies use is also wide-ranging, from the host plants used by the larval or caterpillar stage to the nectar-producing plants used by adult form butterflies.

Flat-surface, composite-petal flowers, like asters, coneflowers, daisies, gallardia, goldenrod, milkweed, and yarrow, are commonly used in the summertime by many adult butterfly species. Dandelions are also in this category, so take a break from weeding, leave just a few, and enjoy butterfly habitat right at home!

Several species of swallowtail, admiral, nymph, skippers and other butterflies also use penstemons, lavender, phlox, rhododendrons and other wild or garden flowers. Fritillaries, blues and painted lady butterflies also use lupines, Oregon grape, spirea and other blooms.

Nectar sources for some species, like Sara orangetip, Mylitta crescent and Woodland skipper, include wildflowers often found near hiking trails at high elevations, like monkey flowers, pearly everlasting, mountain laurel and kinnikinnick.

Butterfly watchers schedule high country field trips this month to catch glimpses of parnassians, coppers, blues, anglewings, and other butterfly species feeding on wildflowers. The Washington Butterfly Association, a chapter of the North American Butterfly Association, is based in Seattle but has members across the state and is a good source of information about these opportunities to learn more about butterflies.

One of the best spots for butterfly watching in Washington is the Washington Department of Fish and Wildlife (WDFW) Sinlahekin Wildlife Area in northcentral Okanogan County, where a total of 90 different species have been identified. This summer butterfly photographer and blogger Caitlin LaBar recorded the Sinlahekin’s 89th and 90th species – the Pacuvius duskywing and the Nevada skipper.

WDFW’s Scatter Creek Wildlife Area just south of Olympia in Thurston County is also known for its butterflies because of its unique short-grass prairie with a wide variety of wildflowers, including some rare or uncommon species.

Another spot with a diversity of butterflies is the Mount Spokane area in Spokane County. Nearly 50 species have been identified there; check out John Bauman’s butterfly guide available at http://www.mountspokane.org.

While watching for butterflies anywhere in Washington, keep your eyes peeled this summer for the Monarch – probably the most familiar butterfly in the world, but one that is somewhat uncommon in Washington. Washington State University research entomologist David James is currently raising and tagging Monarch butterflies, with the help of the Washington State Penitentiary, to learn more about their migrations to California and elsewhere. For information on where to report tagged Monarchs, see website.

Learn more about butterflies in Washington and how to attract them to your yard, not only with nectar-producing flowers for adults but also host plants for the larval or caterpillar stage of the butterfly life cycle.

Birdwatching across the state.
Report what you see to
on-line citizen science projects.

Add to wildlife science while enjoying summertime activities

Whether you’re making a road trip across the state, cooling off in a swimming pool, or just watching the world go by from your front porch, this summer you can add to what we know about wildlife through on-line citizen science reporting projects.

If you’re traveling Snoqualmie Pass on Interstate 90, the Washington Department of Transportation wants your help with its “I-90 Wildlife Watch” -- a citizen-based wildlife monitoring project that invites motorists to report wildlife sightings along I-90 in the Snoqualmie Pass region of Washington. If you observe wild animals -- alive or dead -- while traveling that route between North Bend and Easton, you can make an on-line report at http://i90wildlifewatch.org/, anonymously or with your name. Snoqualmie Pass has been identified as a critical link in the north-south movement of wildlife so the information is needed to help with highway planning to reduce wildlife-vehicle collisions and enhance the safe passage of both motorists and wildlife in the future.

If you own, use, or manage a swimming pool on a regular basis, you could provide valuable information regarding the use of swimming pools by bats. The Center for Bat Research, Outreach, and Conservation wants to learn more because anecdotal reports suggest bats use swimming pools for drinking, perhaps especially in areas where natural water sources are scarce. An on-line survey is available at http://batsandpools.wordpress.com/ through Sept. 15, 2013. Whether you observe bats around your pool or not, your responses are still valuable.

If you’re bird-watching at home or elsewhere, you can contribute to some of the longest running and best known on-line citizen science projects about birds, coordinated through Cornell University’s Lab of Ornithology.

  • NestWatch at http://nestwatch.org/ collects information on the species, nest location, habitat, number of eggs, and number of young to help scientists track the breeding success of birds across North America. Launched in 2007 with funding from the National Science Foundation, NestWatch has collected more than 100,000 nesting records. Combined with historic data, this information helps scientists address how birds are affected by large-scale changes such as global climate change, urbanization, and land use.
  • eBird at http://ebird.org/content/ebird/ is an online tool for birders to keep track of their own lists and contribute their bird sightings for use in science and conservation. Birders, scientists, and conservationists can collect, manage, and store their observations in eBird’s globally accessible database—or use graphing, mapping, and analysis tools to better understand patterns of bird occurrence and the environmental and human factors that influence them. This real-time data resource produces millions of observations per year from across the hemisphere. eBird is a joint project with the National Audubon Society.
  • YardMap Network at http://content.yardmap.org/ is a National Science Foundation-funded project that builds online communities to investigate the impacts of bird-friendly and carbon-neutral practices in backyards, community gardens, and parks. Participants locate their yards or parks on a Google maps interface, then document their sustainable practices, such as adding native plants, putting up bird nest boxes or feeders, installing a solar panel, or biking to work. By providing access to media resources for learning about sustainable practices and enabling people to share their maps and practices with each other, YardMap strives to create online conservation communities engaged in real life sustainable practices. YardMap Network was launched in 2011, in partnership with the National Audubon Society, U.S. Fish and Wildlife Service, and others.

The Washington Department of Fish and Wildlife also has recently initiated its own citizen science projects on a few state wildlife areas where some commitment to initial training and regular visits are required. You can learn more about them at http://wdfw.wa.gov/about/volunteer/citizen_science.html .

We also are interested in wildlife observation reports on-line, specifically on wolf sightings, mountain goat encounters, detections of elk hoof rot deformations, moose sightings and invasive animal species.

Raptors are “early birds” when it comes to nesting

While many birds are just singing their mating songs and building their nests this month, many raptors or birds of prey are already tending hatchlings.

Most of Washington’s 32 species of diurnal and nocturnal birds of prey – eagles, hawks, and owls -- are reproductive “early birds”. That’s mostly because these are larger birds whose young take longer to develop so they need a head start. And like most wildlife species, young are usually produced when food for them is most abundant.

Our most common owl species, the Great horned owl (Bubo virginianus) starts pairing up in mid-January, refurbishing old nest sites in trees, cliffs, or on the ground in February, and can be incubating eggs in March. Young owls may hatch in April, sometimes fledging in May or early June.

Our most common hawk species, the red-tailed hawk (Buteo jamaicensis), is nest-building or refurbishing in March and April. Their big nests of dry sticks and bark are usually in the crowns of tall trees where they have a commanding view of their hunting grounds. Redtails usually produce one brood a year, incubating up to five eggs for about a month and tending to hatchlings in the nest for another month and a half. Young redtails are fledging in late May or early June.

Likewise, our bald eagles (Haliaeetus leucocephalus) and golden eagles (Aquila chrysaetos) are on eggs in perennial nests in March and tending hatchlings into June. Although the bald eagle nest above Lake Washington on our live streaming “Wild Watch Cam” is not occupied this year, video recorded from other years of eaglet-rearing is available at http://wdfw.wa.gov/wildwatch/eaglecam/index.html.

The raptor species that many of us living in urban and suburban areas might encounter most often are two look-alike hawks that prey on smaller birds – the Cooper’s hawk (Accipiter cooperii) and the sharp-shinned hawk (Accipiter striatus). We might see them strafing songbird feeding stations in our backyards during winter, but where are they nesting now?

Cooper’s hawks (the larger of the two, at 14 to 20 inches in length) could be nesting right in town if there are older, larger trees available. Pairs often return to the same general vicinity each year, but they typically build a new nest in an evergreen tree rather than refurbish an old one. They usually lay three to five eggs which are incubated for about a month. Young fledge about a month after hatching but continue to return to the nest to roost and for food for another ten days or so. The young remain near the nest and close to each other for at least five to six weeks. During this time, young Cooper’s hawks gradually begin to hunt on their own.

Sharp-shinned hawks (the smaller species, at 10 to 14 inches in length), prefer to build new nests each year within small groves of dense evergreens that have clearings nearby. Number of eggs, length of incubation, and timing of fledging and hunting independence is similar to the Cooper’s hawk. For both species, the timing of that independence coincides with the peak of songbird fledging in June.

A bird of prey that is an exception to the earlier nesting pattern, migrating back to Washington each year at this time, is the osprey (Pandion haliaetus). These fish-eating birds return in April and early May to nest in treetops or on top of buildings, docks, poles, cell towers, or any other platform near water where they can forage and feed hatchlings next month. You can watch a pair of ospreys on their western Washington nest on our live OspreyCam at http://wdfw.wa.gov/wildwatch/ospreycam/ .

Osprey are fairly adaptable to living near people, but they can get into trouble using some of our discarded materials for nest building. The birds usually line their nests with soft natural materials like grass or moss, but they will frequently pick up baling twine or fishing line if it’s lying around. These materials easily tangle in their sharp talons and can end up killing both adults and chicks; if they are lucky they may only sustain loss of a talon or two. The obvious and easy solution to this problem is to properly dispose of baling twine and fishing line out of reach of ospreys and, for that matter, all wildlife that can become entangled.

While you’re planting this month, include a new tree

April showers and warming temperatures bring out the gardener in many of us.

While you’re out getting your hands dirty this month, consider the future needs of your backyard wildlife by including a new tree in your landscape.

Tree planting, after all, is an American tradition in April, with National Arbor Day officially celebrated the last Friday of the month  --  April 26 this year. The second Wednesday, April 10 this year, is when Washington state traditionally celebrates Arbor Day.

April is also the month we celebrate Earth Day, on the 22nd. Tree-planting is a good way to celebrate this year’s Earth Day theme of fighting climate change because trees help absorb and  reduce carbon emissions and can reduce your own energy costs for a more sustainable lifestyle.

The U.S. Forest Service’s Center for Urban Forest Research reports that trees properly planted around a house can save 30% of your energy use. Shade those south and west sides of your house with trees to keep cooler in summer, and let the sun warm your north and east sides in the winter.  U.S. Department of Energy reports that air conditioners operating in the shade of a tree use 10% less electricity than one in the sun.

There are obviously lots of great reasons to plant trees. The Washington Department of Fish and Wildlife (WDFW) Backyard Wildlife Sanctuary program promotes trees because they provide nesting sites, roosting spaces, escape cover, and food for a diversity of native mammals, birds, reptiles and amphibians, and invertebrates like butterflies and moths.

Tree species native to Washington are your best bets, not only for native wildlife but for ease of care. The following are among good choices, depending on your landscape:

  • Big-leaf maple (Acer macrophyllum) is a fast-growing tree suited for large landscapes that provides homes for cavity-nesting birds and food for insectivorous birds like woodpeckers and nuthatches.
  • Douglas maple (Acer glabrum douglassii) is a small tree used for its seeds by grosbeaks, quail and grouse, for its twigs and bark by deer and beavers, and as a larval host for some moth species.
  • Vine maple (Acer circinatum) is best suited for westside landscapes where it grows naturally in groups as large understory shrubs or small trees. It’s a larvae plant for brown tissue and polyphemus moths, a good nectar source for bees, and seed-producer for a variety of birds.
  • Oregon white oak or “Garry oak” (Quercus garryana) is a thick-limbed, long-lived tree that is Washington’s only native oak. Like all oaks, it produces acorns loved by everything from Clark’s nutcrackers to tree squirrels, and at maturity they often provide cavities for nesting and roosting by both birds and mammals.
  • Pacific dogwood (Cornus nutallii) has large, creamy-white, showy flowers eaten by spring azure butterfly larvae. A diversity of birds, including bluebirds, sapsuckers, white-crowned and song sparrows, tree swallows, towhees, and vireos eat its fruit.
  • Cascara (Rhamnus purshiana) is a native small tree or tall shrub that grows well in disturbed sites. Its berries are eaten by grosbeaks, grouse, jays, robins and tanagers, as well as bears, foxes, coyotes and raccoons.
  • Native birches (Betula spp.) are hardy clump-growers to plant far from drain pipes or foundations, but they produce lots of wildlife habitat: seeds for juncos, siskins and other birds; insects for kinglets, warblers and other birds; bark for nesting material; leaves for mourning cloak and swallowtail butterfly larvae; twigs for elk, deer and small mammals; cavities for birds and other wildlife.
  • Native hawthorns (Crataegus spp.) are more shrub-like than tree, with densities that often provide good escape cover for songbirds. Berries are favored by robins, waxwings, wood ducks, turkeys, black bears, coyotes and foxes, to name a few.
  • Native pines (Pinus spp.), which can be fast-growing large trees best suited for larger properties, provide nesting sites for many songbirds and seeds for, among others, crossbills, mourning doves, jays, finches, siskins, and chipmunks.
  • Douglas-fir (Pseudotsuga menziesii) grows quickly with a dense screen of soft needles that are used by silver-spotted tiger moth larvae, among others; its seeds are eaten by grouse and many songbirds, its associated insects are eaten by brown creepers and woodpeckers, its twigs are browsed by deer and elk; at maturity its cavities harbor flying squirrels and other animals.
  • Western hemlock (Tsuga heterophylla), Washington’s state tree, is favored by elk and deer for its delicate feathery foliage, and juncos, siskins, chickadees and squirrels for its seeds.

Lots more detail about these and many other trees for wildlife is available in the book by WDFW wildlife biologist Russell Link, “Landscaping for Wildlife in the Pacific Northwest” (http://wdfw.wa.gov/living/book/index.html .)

Certified arborists are excellent professional resources on tree installation, care, and maintenance and can be found through the Pacific Northwest chapter of the International Society of Arboriculture (http://www.pnwisa.org/.)

Wildlife action – and viewing -- ramps up this month

Wildlife activity – and wildlife viewing opportunities – ramp up considerably in March.

With the Spring equinox on March 20, when daylight hours equal nighttime darkness, migrating birds are on the move, hibernating mammals begin to emerge from winter dens, breeding and nesting gets underway, and foraging on the first greens of the season is fast and furious for wild animals growing young of the year.

You can view some of the action right from your home. It might be a sudden influx of migrating blackbirds or waxwings descending on a backyard bird feeding station or berry-producing shrub in your landscape. Maybe you’re seeing marmots or ground squirrels out and about, or skunks or raccoons checking out the real estate under your front porch. Or you’re fending off winter-weary and hungry doe deer nibbling the buds on your first crocuses or tulips.

The Spring wildlife action is even greater in scale, scope and diversity at many of the Washington Department of Fish and Wildlife (WDFW) wildlife areas and U.S. Fish and Wildlife Service wildlife refuges across the state. You can locate these public lands to plan visits at http://wdfw.wa.gov/lands/wildlife_areas/ and http://www.fws.gov/refuges/refugeLocatorMaps/washington.html .

Wildlife viewing festivals ramp up this month and next, too. Many provide a great way for families and groups of all ages to enjoy the outdoors and learn more about birds and other wildlife through tours, lectures, displays, and children’s activities. Here’s what’s coming up soon in Washington:

  • March 14-16 is the 11th annual “Wings Over Water” Northwest Birding Festival in Blaine, WA. This free festival, with the majority of events on Saturday, March 16, celebrates the abundance of wildlife and bird species in this pristine area of the Pacific Northwest. It includes guided field trips, live raptor displays, workshops, educational activities, expert wildlife speakers and more. It’s sponsored by many private groups and individuals, including the Birch Bay Chamber of Commerce, North Cascades Audubon Society, and Washington Brant Foundation, For more information, see http://wingsoverwaterbirdingfestival.com/index.html
  • March 16 is the Tundra Swan Festival at Calispell Lake in northeast Washington’s Pend Oreille County, sponsored by the Kalispel Tribe Natural Resources Department, Pend Oreille River Tourism Alliance (PORTA), and others. Pre-and post-swan-viewing talks are at the Kalispel Tribe’s Camas Center for Community Wellness at Usk. For more information and registration see http://www.porta-us.com/pages/activities/tundra_swan_day.asp
  • April 5 – 7 is the Olympic Bird Fest in Sequim, WA, a partnership of the Olympic Peninsula Audubon Society, Dungeness River Audubon Center and Jamestown S'Klallam Tribe, with grants from the Olympic Peninsula Visitor Bureau and Sequim Marketing Action Committee.  Events include birding cruises, “owl prowls”, wildlife photography workshops, raffles, auctions and a banquet. Proceeds from this festival help support the educational programs of the Dungeness River Audubon Center. http://www.olympicbirdfest.org/ 
  • April 5 - 7 is the 16th annual Othello Sandhill Crane Festival in central Washington’s Columbia Basin, celebrating the spectacular spring migration feeding and resting stopover of thousands of these big birds in the local agricultural fields. This festival is sponsored by the Greater Othello Chamber of Commerce and the USFWS Columbia National Wildlife Refuge, and supported by the City of Othello, Othello School District and Othello Community Schools. Details of scheduled crane viewing and other wildlife tours, talks and events, including a traditional Saturday night banquet with keynote speaker, are available at http://www.othellosandhillcranefestival.org/ .

Winter bat sightings could spell trouble

Bats are not the kind of wildlife you expect to see in freezing winter conditions.

They hibernate during the cold months, or they’re long gone to warmer climes where their insect diet is more abundant.

So if you notice bats active during freezing weather, or find dead bats in winter, it might signal a problem for these little flying mammals.

The bat species that don’t migrate south, but instead hibernate locally, may be most vulnerable to a rapidly spreading fatal disease at this time of year. White-nose syndrome (WNS), which has not yet been detected in Washington but has been killing bats in North America for the past six years, is caused by a newly described fungus (Geomyces destructans) that thrives in the conditions of winter hibernating habitat – cold, humid spaces like caves and mines where bats can decrease their body temperatures to maintain a state of hibernation.

The fungus invades a bat’s skin tissues, eats holes in its wing membranes, and in general interferes with its ability to survive at a time when it is living off its fat reserves and is most susceptible to infections and disturbance.

“Most bat species in Washington and other cold regions of North America enter hibernation with about as much fat as you’d find in a pat of butter,” said Washington Department of Fish and Wildlife (WDFW) biologist Ella Rowan. “To survive off that tiny amount of fat, they need to decrease their metabolism, decrease heart and respiratory rates, and nearly shut down their immune systems and other physiological mechanisms. That leaves them vulnerable to infections.”

Rowan explained that hibernating bats arouse every couple of weeks to eliminate wastes and perform other critical body functions. That uses a great deal of energy from their fat reserves; if they are aroused too often, they might use up all of their fat before spring. The fungus that causes WNS is invading bats during hibernation, often causing them to arouse more frequently, perhaps in an attempt to groom off the white powder-like fungus or turn on their immune systems. The infection may also be interfering with their ability to remain hydrated and perform other critical physiological functions while hibernating.

Bats can pick up the fungus from an infected environment and transfer it to each other through direct contact. Evidence indicates the fungus can also be transferred from one site to another by humans on clothing, boots and cave exploration gear.

Currently, 19 states and four Canadian provinces in the east and midwest have bats with WNS and infected caves and mines. WNS currently causes mortality in seven species, with over six million bats estimated to have died from the disease since 2007. Biologists have seen declines to the extent that one species is predicted to go extinct in the northeastern part of the U.S. by 2020.

Although the disease is not yet known to exist in Washington, Rowan says concern is rising because the fungus and disease are spreading in all directions across North America.

“Perhaps the states and provinces of the Great Plains will offer a barrier to the spread of the disease,” Rowan said, “but people who travel to, and work in, caves, mines and other areas where our bats hibernate might unintentionally introduce it from somewhere outside Washington. We need everyone’s help to avoid that.”

Rowan says details about decontaminating clothing, boots and gear are described in the latest approved protocol from the U.S. Fish and Wildlife Service at http://www.whitenosesyndrome.org/topics/decontamination .

“Any reports through February of active bats in the freezing regions of Washington, or numerous bats found dead, would be an alert for us to look for this disease,” Rowan said.

Reports of dead or winter-active bats in the freezing regions of Washington can and should be made immediately at 800-606-8768.

“Bats provide invaluable ecosystem functions in their insect predation and nutrient transfer roles,” Rowan said. “Biologists in the northeastern U.S., where this disease is now widespread, say they have ‘silent nights’ now when they conduct evening acoustic surveys for the sounds of bats. We hope we never have such silent nights here in Washington.”

January 2013 UPDATE

UPDATE: Can we de-ice our roads without hurting wildlife?

The subject of this month’s “Crossing Paths” news note on de-icer impacts to wildlife solicited comments, including some from our own biologists, about how fish and amphibians can be hurt by road salt and sand.

We focused on birds because they’re familiar to most but their attraction to salt, like mammals, is unfamiliar to many. We didn’t mean to suggest that de-icers of any kind don’t have other negative impacts to other wildlife.

Research does indeed show that use of salt or sand on roadways with significant run-off into adjacent waterways or wetlands can hurt fish, amphibians and other aquatic fauna and flora. That’s why the Washington Department of Transportation (WSDOT) tries to minimize its use, or use non-salt alternatives, in those situations, according to WSDOT wildlife biologist Kelly McAllister.

There is no perfect solution to both keeping our roads safe for winter motor vehicle traffic and avoiding impacts to fish and wildlife.

The use of sand for road traction instead of de-icers is not without problems. Our southcentral regional habitat manager Perry Harvester notes that sand application can have significant adverse impacts to fish life, particularly in-stream incubating eggs and alevins of salmonids.

“In areas of heavy sand application,” Harvester said, “the sand builds up along the road shoulders adjacent to streams, and during the first big rain-on-snow event in the spring, this sand and grit is flushed into the streams. In smaller streams that are already at critical threshold for fine sediment loading, it doesn’t take much additional sediment to result in a significant increase in mortality of eggs and alevins of salmon, trout, and steelhead.  If silt or sand fills in the spaces between the spawning gravel, clean water cannot circulate and the eggs may die from lack of oxygen, accumulated waste products, or physical encasement.”

Both McAllister and WDFW southcentral district wildlife biologist Jeff Bernatowicz also note that more recent use of Calcium chloride (CaCl) and Magnesium chloride (MgCl), instead of Sodium chloride, seems to attract some wildlife even more – despite some research that indicates it’s the sodium part of de-icer that attracts animals.

 “I wondered why we were seeing more animals on highways and suddenly licking clean our vehicles at winter feed sites,” Bernatowicz said. Prior to the use of Magnesium chloride, we never had sheep on Highway 821 along the Yakima River between Ellensburg and Yakima.  But now, if snow is forecast and that road is sprayed, and if the snow is light and melts, sheep will be on the highway in the morning.”

Bernatowicz conducted an experiment at a bighorn sheep winter feeding site by setting up 55-gallon plastic drums at the site, some sprayed with a commercially available solution of MgCl and some with dissolved table salt (Sodium chloride).  He ran three trials, rotating the location of the barrels, and in each trial the sheep licked the MgCl barrels clean first.

Because the commercially available formulations of MgCl include proprietary compounds that reduce the corrosiveness of the salt, it’s unclear what element of the mixture is so attractive to sheep.  While ingestion of the product may not hurt wildlife, it does seem to attract wildlife. And attracting large animals like bighorn sheep, elk or deer to roadways is highly hazardous, both for drivers and for the animals.


January 2013

Can we de-ice our roads without hurting wildlife?

When Washington winter conditions include ice on our roads, driveways and sidewalks, de-icer applications become a safety necessity. But can we have safe human travel corridors without hurting wildlife attracted to salt and grit?

Wildlife biologists say the answer is “maybe” and it depends on what’s used where.

De-icers used by federal, state and local government road crews, as well as by private citizens at home and work, are mostly one of three types: 1) salt based (usually sodium chloride or common table salt, but also magnesium chloride, potassium chloride, and calcium chloride), 2) acetate based, or 3) sand.

Salt based de-icer has been used for over a century in North America and remains the most commonly used type because it is relatively inexpensive, available, and effective.

Large mammals, such as moose, elk, deer, bighorn sheep and mountain goats, are attracted to road salt, which sometimes becomes a factor in motor vehicle collisions with these big animals.

Perhaps less familiar to most is the attraction to salt by some birds.

“It’s all about the salt for winter finches,” said Washington Department of Fish and Wildlife (WDFW) biologist Chris Anderson.

“Winter” or Cardueline finches, of the Fringillidae family, including siskins, crossbills, grosbeaks, finches, goldfinches and redpolls, are seed-eaters that move south in winter when seed is scarce in their more northern breeding areas. They are known to love salt, with research showing they prefer sodium over other minerals, regardless of size. Salt is used by birds not only to fill a need associated with a vegetarian diet, but also as grit to aid in the grinding of food in their crops.

But research shows that birds ingesting relatively small numbers of road salt granules or small quantities of sodium chloride solutions, are at risk of sodium poisoning.

Normally the salt glands of birds excrete sodium and chloride to maintain proper chemical balance. But those glands can be compromised by lack of access to fresh, open water or exposure to certain pesticides or oil, and birds die of salt “poisoning” or toxicosis.

Cold weather that freezes areas of freshwater may force birds to use more saline waters that remain open because of the high salt content, including melted snow on roadways. Using salt water to dilute salt ingestion only makes the problem worse.

If birds aren’t killed by the road salt itself, they are killed when motor vehicles collide with them on those roads. In fact, some research indicates salt ingestion increases the vulnerability of birds to vehicle collisions by causing impairment – they are too weak or slow to avoid moving vehicles.

In one Canadian location – Mount Revelstoke Park --  road mortality of siskins and other winter finches has been seen frequently enough over the last 25 years for the birds to be called “grille birds” by the locals, in reference to their propensity to be collected by the front end of moving vehicles.

WDFW biologist Ella Rowan, who monitors WDFW’s Wildlife Health hotline, says a call or two every year comes in about whole flocks of dead birds in a road, usually winter finches and perhaps where they were ingesting salt-based de-icer.

So what about the other de-icer types?

Acetate-based de-icers include Calcium Magnesium Acetate (CMA), Potassium Acetate, and Sodium Acetate. Research indicates CMA and potassium acetate do not attract animals and are harmless to them if ingested. Sodium acetate, however, may attract animals and contribute to roadkills.

Sand, of course, is natural, usually composed of crushed aggregate or pure river sand. It has been used to increase road or foot traffic traction at least as long as salt, but it obviously doesn’t have the actual “de-icing” effect of salt. Sand has no negative impact on wildlife, but in the amounts needed to keep roadways safe, it is more expensive.

Washington Department of Transportation (WDOT) wildlife biologist Kelly McAllister says applying affordable de-icers on our state’s roads is vital to the safety of winter travelers and we need to look for solutions that don’t compromise safety. Acetate-based de-icers are very expensive – usually in the range of four to five times as expensive as salt-based – they aren’t as effective, and they have high oxygen demand when they run off into road-adjacent waterways, he says.

“Providing salt sources for wildlife away from roads is something that is being tried,” McAllister said. “I think making open water more available to birds that are ingesting salt, to reduce the effects of toxicosis, is another part of the solution, but it’s obviously difficult to do on a large scale during freezing weather. We’re open to ideas and citizen help.”

WDFW biologists like Anderson and Rowan recommend that wildlife enthusiasts start at home. Use sand or acetate-based de-icers on sidewalks and driveways, or if you must use salt, use it very sparingly and keep it stored out of reach of wildlife.  Maintain open water for birds during the winter, either by replenishing water at least daily or by using a safe bird bath heater element; keep bird baths clean to avoid spreading disease. Provide grit (sand or crushed egg shells) in a feeder to reduce the need for birds to go to roadsides.

And, as always, help birds stay healthy in general by maintaining  year-round, sustainable habitat for wildlife in your own backyard. If you like watching winter birds close-up by providing supplemental feed, please keep feeders clean and use clean, dry feed only to avoid spreading disease.

How does wildlife weather winter?

How does the wildlife you enjoyed seeing in your backyard earlier in the year survive all the changes in conditions that come with winter weather?

Some species are no longer visible, but that’s not necessarily because they left the area. Others may be even more visible, depending on what’s available in your yard.

“Winter is a lean time for all wildlife,” says Washington Department of Fish and Wildlife (WDFW) biologist Chris Anderson. “It’s the season that naturally helps keep wildlife population levels in check and in balance with available habitat. To survive, animals exhibit different behaviors, strategies, and activity patterns, based on their biological needs.”

Anderson notes that the behavior most commonly seen by most people is migration. For some species it makes more sense, from an energy-efficiency standpoint, to migrate out of one area, where winter conditions make food more scarce, to another area where food remains plentiful.

Many birds do just that, most in large groups that are highly visible in fall and spring. Others move out in smaller family groups. Osprey will head south to California or all the way down to Argentina for more favorable climatic conditions to rest and fish. Two of our 15 species of bats -- hoary and silver-haired bats – also migrate to warmer climes.

Some non-winged, land mammals also migrate, although it’s more “vertical” – moving from higher elevation summering grounds to lower elevation wintering areas. Elk, deer, and moose are the most obvious examples; as prey species, they are followed by carnivores like cougars, coyotes and wolves.

Many animals go into hibernation, where their metabolism slows down in order to exist largely on stored fat for the winter. Most of our bat species hibernate. Their body temperature, breathing, and heart rate drops. They occasionally come out of this state to eliminate waste, lick condensation from their fur for a drink, or even go out and hunt insects if warm spells are conducive to insect activity.

Bears also hibernate. Their metabolism slows and they go into a sleep-like state, although their body temperature doesn’t drop so much. They are in their den avoiding the stressful winter, living off the fat they accumulated when the vegetative bulk of their omnivorous diet was abundant. Bear sows are pregnant when they go into their hibernation den, and will birth their young in late winter in the safety of that den.

Many frogs, snakes and other amphibians and reptiles find areas within their preferred habitat to stay out of the “freeze zone”. These areas include the bottom of a pond that does not freeze totally, below rock piles, in rocky cliffs, and under large trees and snags. They go into a reduced metabolic state known as “brumation” – the equivalent of  mammalian hibernation for cold-blooded reptiles and amphibians.

Many animals use dormant periods of decreased activity, with reduced body temperature and metabolism rate, known as “torpor.” It’s a way for some animals, from mice to birds, to eke through a physically stressing period of extreme temperatures or reduced food availability. This can be for just one very cold night, the entire winter, or in overly hot situations. 

Anderson notes many people who manage year-round habitat on their property see some wildlife species mostly or sometimes only during the winter. For example, seeds from that alder tree in the backyard are now drawing dozens of pine siskins, many which are year-round residents that are more dispersed in the summer and not usually seen in such concentrations except in winter.

“Providing high quality year-round habitat, both on your property and on others’ by working with local habitat enhancement groups, is one thing you can do to help wildlife weather winter,” Anderson said.

“Another crucial thing we can all do is avoid disturbance of these animals during these energy-stressed times, including migration, hibernation, and feeding and resting on wintering grounds,” Anderson said. “Leave them be, respect their space and needs, and be their advocate!”

Anna’s hummingbird
In western Washington, some Anna’s hummingbirds can be
year-round residents.

November 2012

Should winter bird feeding include hummingbirds?

As fall advances towards winter and bird feeding stations are set up in many Washington backyards, should hummingbird nectar feeders come down or be maintained?

In eastern Washington, the answer is simple: nectar feeders come down because the birds are gone. The three species of hummingbirds that can be seen at eastside backyard feeders during the spring and summer – rufous, calliope and black-chinned – have migrated south to wintering areas by now.

In western Washington, the answer is a little more complicated because some Anna’s hummingbirds can be year-round residents. But would leaving nectar feeders out in westside backyards lure rufous hummingbirds into staying when they should head south?

Washington Department of Fish and Wildlife (WDFW) biologists say most research on whether feeders of any kind keep birds from migrating indicates that the impact is insignificant, at least from a species population standpoint. It’s possible that a few individuals might linger longer, maybe even be stranded in winter conditions when they should be someplace else. But for the most part, birds that migrate seasonally will do so, even if feeders are left out.

In fact, during the last decade of annual Christmas Bird Counts (CBC) in Washington, no black-chinned or calliope hummingbirds were counted and only one rufous hummingbird (in 2002) was counted. Anna’s hummingbirds, on the other hand, are always in western Washington CBC tallies; 179 were counted in 2001 and 1,137 in 2011 (an increase that may be as reflective of the number of actual observers and count areas as birds attracted to more feeders.)

WDFW biologist Patricia Thompson of Mill Creek notes that the 1993 – 2001 Winter Backyard Bird Surveys she compiled seemed to show an increase in the number of Anna’s and rufous hummingbirds over the years, although she’s not sure why.

Biologists agree that a greater long-term impact on bird migration is probably climate change and associated changes in available natural habitat across the landscape. Birds have many triggers that drive them to migrate, not the least of which is changing daylight hours.

Biologists also agree that feeders of any kind are not necessary for any birds, they simply make viewing birds easier for us. For most birds, feeders are bonus food troughs but not necessarily food traps.

“We need to support natural winter processes,” said WDFW biologist Chris Anderson of Mill Creek, “and that includes shifts in foraging areas for migrating species like hummingbirds. Taking nectar feeders down at this time of year is probably more natural and avoids the potential for keeping birds dependent on them when they should be moving on. Wild birds are not pets that need to be taken care of through feeding. But if you want to maintain feeders, be responsible and committed to it. Keep those feeders clean, filled, and heated with lights if necessary.”

Advice from Audubon, American Bird Conservancy, and the Cornell Lab of Ornithology includes only keeping hummingbird feeders up for two weeks in the fall after you see the last bird using them. They also say:

Maintaining a backyard hummingbird feeder can help provide the birds with nectar critical to their survival, especially during the fall when they need to double their body mass before migration. (Contrary to a common fear, the extra food won't stop a hummer from migrating south when it's time for it to go.) To ensure your yard is a safe and nutritious stopover for hummingbirds:

  • Fill the feeders with sugar water, made by combining four parts hot water to one part white sugar, boiled for one to two minutes. NEVER use honey, which promotes the growth of harmful bacteria, or artificial sweeteners, which have no nutritional value. Also avoid red food coloring.
  • Clean the feeders with a solution of one part white vinegar to four parts water about once a week. If your feeder has become dirty, try adding some grains of dry rice to the vinegar solution and shake vigorously. The grains act as a good abrasive. Rinse your feeder well with warm water three times before refilling with sugar solution.

Hawthorne nut, one of the many seeds and fruits used by birds and wildlife species during this time of year.
Right now many birds and other wildlife species are using the seeds and fruits of hawthorn, maple, ninebark, mountain-ash, Oregon-grape, evergreen huckleberry and other species.

Delay pruning to help wildlife now

Fall yard and garden clean-up too often includes pruning trees, shrubs and other plants that wildlife may depend on for food and cover.

Washington Department of Fish and Wildlife (WDFW) staff recommend delaying that task to help wildlife during the more difficult fall and winter season.

“If pruning is necessary, the most wildlife-friendly time to make those cuts is late winter,” said WDFW biologist Russell Link. “Right now many birds and other wildlife species are using the seeds and fruits of hawthorn, maple, ninebark, mountain-ash, Oregon-grape, evergreen huckleberry and other species.”

Link advises leaving dried foliage, seed heads and some grasses uncut, too, as many of these annuals and perennials keep their seeds well into winter, or harbor insects that many birds use throughout the winter.

“If you clean and prune in fall,” Link said, “try leaving cut vegetation around the plant as a mulch and to hold seeds and over-wintering invertebrate eggs and larvae. And consider adding cut branches and twigs to an out-of-the-way brush pile which creates its own habitat.

Controlling invasive non-native vegetation like Himalyan blackberry is another matter. Heavy pruning, outright removal, or removal and replacement with a locally-adapted native species, is recommended, and fall is a great time to plant.

Link also notes that some homeowners don’t get the gardening bug until spring is in full-bloom. Pruning trees and shrubs in spring is the least wildlife-friendly, as it can be disastrous for birds and other wildlife that are setting up territories, nesting, or rearing young.

“Timing is everything,” he said. “Pruning trees and shrubs is best for the plant when it’s shutting down for the season. Delaying that traditional fall chore until late winter is best for wildlife.”

Black bear in urban garbage can
Deer can live normally with a moderate infection of warts caused by the papillomas virus.

Do your deer have warts?

If you’re one of the many Washington residents who regularly enjoy seeing deer in or around your neck of the woods, sooner or later you may see warts.

We don’t mean the not-so-nice side of deer, like munching your roses or dirtying up your lawn. We mean actual warts on the deer.

And at the Washington Department of Fish and Wildlife (WDFW), we hear about them from concerned citizens (including deer hunters) all the time all across the state.

Actually they’re called papillomas or fibromas or fibropapillomas -- usually benign wart-like growths fastened to the skin of the deer. They are firm, hairless, gray or black in color, can be smooth or rough in texture, as small as peas or as large as footballs, and may grow in clusters. Sometimes they can become so heavy that they hang like a pendulum from the deer, and they may be found anywhere on the animal’s body.

These growths do not usually cause the animal any harm. Papillomas only involve the surface of the skin and do not normally affect the behavior or general health of the deer unless they block the deer’s vision or become a physical impediment to walking, running, or eating. Deer can live normally with a moderate infection of papillomas.

These growths are caused by viruses that are contagious within the same species. Papilloma viruses that infect one species usually do not infect another species. Typically, papillomas will eventually outgrow their blood supply, dry up and disappear. Fawns exposed to the papilloma virus can develop immunity early in their life.

All species of mammals are probably susceptible to their own type of papilloma virus, but in Washington papillomas are most frequently observed on deer, elk, and moose.

Papilloma viruses are transferred from animal to animal by biting insects, direct contact between deer, or sharing rubbing posts and bedding sites.

Deer papillomas do not affect people, pets or livestock. These viruses are very species-specific. Pets and livestock, however, can become infected with papilloma viruses that affect their own species.

Deer hunters who harvest an animal with papillomas can simply trim them away when field dressing, leaving the venison unaffected and suitable for consumption.

If you see a deer with warts, chances are it will be just fine. But if you believe we need to know about it, contact your local WDFW office (http://wdfw.wa.gov/about/contact/).

Black bear in urban garbage can
Seeing a black bear in your backyard may initially seem like novel summertime entertainment.

Bears need your help to get out of town

(excerpted in part from “Bears101: No garbage, birdseed ,dog food”, Wenatchee World, July 4, 2012)

Seeing a black bear in your backyard may initially seem like novel summertime entertainment.

But Washington Department of Fish and Wildlife (WDFW) carnivore specialist Rich Beausoleil of Wenatchee says bears that find a predictable food supply can get used to living too close to people and can become bolder over time. Such situations, he says, usually end up bad for the bear.

Beausoleil and his Karelian bear dog Cash respond to dozens of problem bear situations every year. Sometimes bears involved in conflicts can be captured and relocated, with the hope they will avoid food sources associated with people. But other times bears that just can’t avoid these high quality food sources have to be euthanized.

People can prevent bear conflicts if they remember bears are driven to consume as many calories as possible during the summer, Beausoleil says, and if they manage three common sources of those calories: garbage, birdseed, and pet food.  

“Bears don’t want to be around us,” he said, “but we make things so tempting and appetizing for them. Unsecured garbage, birdseed in feeders throughout the summer, and pet food left outside are easy, high-calorie meals for bears. You can’t blame a bear for wanting to hit the drive-through rather than spending hours picking berries to pack on the pounds in the six months before the denning period begins.”  

In Washington counties like Chelan, with many both year-round communities and summertime homes and cabins around lakes, rivers and mountains, it’s especially important to keep bears in mind. Garbage management alone is key to keeping bears away from people.

Bear-proof garbage containers, from community dumpsters to individual cans, is one way to prevent problems. Just changing community garbage pick-up schedules can help. Instead of putting garbage cans out at night for early morning pick-up, keep garbage secure indoors until morning for mid-day pick-up.

And Beausoleil knows of at least one case of vacationing residents or summertime cabin owners paying a neighborhood youth to manage garbage in their absence to avoid problems with bears.

“These people, they’re getting it,” Beausoleil said. “If we could get more people thinking like this, we would eliminate these problems.”

White-tailed deer fawn
Doe deer leave their fawns alone to avoid drawing predators with their own body scent.

Now playing: The invasion of the baby snatchers

It’s fawn-napping time again.

And we don’t mean baby deer taking naps.

No, unfortunately it’s that time of year when too often too many people “kidnap” fawns -- and other wildlife babies -- found outdoors.

They often think they’re saving an abandoned baby, says Washington Department of Fish and Wildlife (WDFW) biologist Patricia Thompson.

“But most of the time they’re actually kidnapping a baby out from under the watchful eye of a nearby but unseen mother deer,” Thompson said. “It’s the annual re-run of “The invasion of the baby snatchers.”

Thompson, who coordinates Washington’s licensed wildlife rehabilitator program, takes calls nearly every day at this time of year from well-intentioned but uninformed people.

Sometimes she can talk people into leaving the fawn where it is or putting the fawn back where they found it so the doe can reunite with her baby again. But too often she has to enlist the help of a licensed rehabilitator trained in wild animal care.

“An uninjured fawn really doesn’t need human care,” she said. “It needs its mother. In the rare case of a truly orphaned fawn, it needs a special diet and treatment, as well as no human contact to eventually be rehabilitated back to the wild.”

Thompson says it’s frustrating because WDFW has been promoting “leave wild babies in the wild” forever, and information has been available for years on WDFW’s website (http://wdfw.wa.gov/conservation/health/rehabilitation/when_not_to_rescue.html).

“Sometimes I think people just can’t help themselves,” she said. “When a wild baby seems helpless or abandoned, you want to help.”

But that help can ultimately be a death sentence for young wild animals, which are often intentionally left alone for hours while their parents gather food.

Doe deer leave their fawns alone to avoid drawing predators with their own body scent. Young birds commonly leave the nest before they are fully-feathered and are fed on the ground by their parents for a day or two until they are able to fly. It is common to see very young American robins, spots and all, on the ground waiting to be fed by mom or dad.

More often than not, just leaving a young animal alone affords it the best chance for survival.

Leaving these babies alone means you need to confine cats, dogs and other pets that can cause lethal injury. One of the most common causes of injuries to wildlife, is attacks by cats. Any animal attacked by a cat needs a wildlife rehabilitator’s care, even if it does not look injured.  Cat bites often cause serious infection.

One of the few situations in which almost anyone can help wild babies is when very young, un-feathered birds have fallen out of the nest and are on the ground.

If you can find the nest and safely reach it, simply pick up the nestling with a gloved hand and put it back in the nest. Contrary to popular belief, the parent birds will not reject their young because it’s been handled by humans.

Thompson recently reported a situation where a fawn was hung up in a fence, probably while trying to follow its mother. It was freed by a neighbor who watched it run around by itself for a day, but then witnessed it reunite with its mother to nurse.

In another recent incident, a fawn brought in to a licensed wildlife rehabilitator was returned to the pick-up spot within 24 hours. When released by the rehabilitator, the fawn cried out and within minutes a doe appeared, stomping its feet at the human (who quickly exited so the two could reunite.)

Wild animals of any age that show obvious signs of illness or injury such as bleeding, vomiting, panting, shivering, or ruffled feathers or fur, or that are just lethargic and make no effort to escape your approach, may indeed be in need of care. However, call a wildlife rehabilitator first before attempting to pick the animal up.

Most Washington counties have wildlife rehabilitators, listed with phone numbers and addresses for 24-7 access on the WDFW website at http://wdfw.wa.gov/conservation/health/rehabilitation/index.html.

If you and a wildlife rehabilitator decide it might be best to help the animal, find out from them how to safely contain and transport the animal. Always wear gloves when picking up a wild animal to place it in the container. Until the animal is transported to the rehabilitator, keep it in a warm, quiet, dark place.

Another way to help wildlife, whether or not you find an injured animal in need of care, is to support your local volunteer wildlife rehabilitators. All of these volunteers must establish and maintain a good working relationship with a cooperating veterinarian, and many are veterinarians themselves; none can charge for their services to wildlife, but may accept donations.

May 2012

This month is for the birds!

May marks the return of many birds to or through Washington, making backyard and other nearby viewing a veritable showcase of color and song.

Everything from Canada geese to calliope hummingbirds is busy in some stage of courting, breeding, nesting, or rearing young – or is on its way to traditional spring and summer range even further north.

Those birds that remain in Washington year-round – like the chickadees, nuthatches, woodpeckers, finches and other species regularly seen at backyard winter feeding stations – are also suddenly brighter in color and singing to establish breeding and nesting territories, going through mating rituals, and building new nests or remodeling old ones.

But it’s the “neo-tropical” species that winter in Central or South America that return or pass through now, triggered mostly by longer daylight hours, that especially catch our eye with exotic flashes of yellow, red, blue and other hues.

Warblers are some of the most noticeable and numerous -- orange-crowned, yellow-rumped, black-throated gray, Townsend’s, yellow, MacGillivray’s, Wilson’s, and common yellowthroat.

Our many swallow species, several named for nesting preferences, grab attention with their aerial acrobatics – tree, violet-green, bank, cliff, northern rough-winged, barn, and purple martins.

And of course backyard birders who provide sugar water in feeders are delighting in the return of our hummingbirds – black-chinned, Anna’s, calliope, and rufous.

Other neotropicals are just as bright or melodious, including ruby-crowned kinglets, mountain and western bluebirds, Swainson’s, hermit and varied thrushes, western tanagers, black-headed grosbeaks, lazuli buntings, yellow-headed blackbirds, Bullock’s orioles, house wrens, Vaux’s and white-throated swifts, and chipping, Brewer’s, lark, fox, savannah, Lincoln’s, vesper, and white-crowned sparrows.

Celebrating this influx of species is International Migratory Bird Day, always the second Saturday of May, with many events across Washington then or sometime this month, including:

Help wildlife – and yourself – by going native this Spring

Like many gardeners, Backyard Wildlife Sanctuary managers are lured at this time of year to colorful new plants displayed in nurseries and home improvement stores now.

But if you’re adding plants to your landscape this Spring, consider doing more for the wildlife you want to attract -- and go easy on yourself --  by going native.

Native plants naturally provide just the right food and cover for birds, bees and other critters. They’re also easier on you and kind to the earth in general because their maintenance requirements are suited to our climate. That means less watering, less fertilizing, less pest control, less winter mulching -- less care and resources overall to sustain them year after year.

Anyone thinking that native plants can’t possibly be as attractive as those exotics now on display hasn’t taken a look at natives in our neck of the woods.

It’s hard to beat the beauty of columbine, bleeding heart, coral bells, penstemon and honeysuckle – all natives, all beloved by hummingbirds for their nectar.

Showy but native rhododendrons, lupines and phlox support butterflies.

And asters, blanketflower, daisy fleabane and wild sweet peas produce seeds used by a variety of songbirds.

There’s no better time to go native than this month as we celebrate not only Earth Day on April 22, but also Native Plant Appreciation Week , April 29 – May 5.

You can learn more about native plants in our area and resources for acquiring them from the Washington Native Plant Society at www.wnps.org.

American goldfinches at birdfeeder.
A growing number of western Washington reports of birds sick or dead from a disease that spreads at bird feeders.

Remove and clean bird feeders to avoid disease

A growing number of western Washington reports of birds sick or dead from a disease that spreads at bird feeders has the Washington Department of Fish and Wildlife (WDFW) recommending temporary feeder removal and thorough cleaning.

“It looks like this could be a salmonella year,” said Patricia Thompson, WDFW biologist based in Mill Creek who coordinates the state’s wildlife rehabilitator program. Thompson has recently received reports from Bainbridge Island, Bellingham, Everett, Kirkland, and Sammamish.

Wildlife veterinarians with PAWS Wildlife Center in Lynwood and wildlife rehabilitators at West Sound Wildlife Center on Bainbridge Island recently told Thompson of birds found sick or dead at backyard feeders in these and other areas; necropsies on three dead pine siskins found lesions in each consistent with salmonellosis.

Salmonella is a bacteria, transmitted through bird droppings at feeders, that causes the  most common and usually fatal bird disease called salmonellosis. The disease afflicts species such as finches, grosbeaks and pine siskins that flock together in large numbers at feeders.

Thompson said salmonellosis and other bird diseases are spread at backyard feeding stations that are not meticulously maintained.

The first indication of the disease is often a seemingly tame bird on or near a feeder. The birds become very lethargic, fluff out their feathers, and are easy to approach, but there is very little that can be done to treat them.

It’s possible, although uncommon, for people to become sick from the salmonella bacteria through direct contact with infected birds, bird droppings, or through pet cats that catch sick birds. People who handle birds, bird feeders or bird baths should wear gloves and wash their hands thoroughly afterwards. More information on human health and salmonella is available at http://www.doh.wa.gov/EHSPHL/factsheet/salmonel.htm.

When disease is noted or suspected in local birds, Thompson said, feeders should be taken down for two to three weeks or more to reduce concentration of sick birds at feeders and curb spread of the illness.

“Birds use natural food sources year-round, even while using bird feeding stations,” she said, “so there’s no need to worry about birds getting food. It’s more important to remove a source of disease that can kill more birds.”

Those who have not seen sick or dead birds at or near their feeders, or have not heard about problems at neighborhood feeders, should still be thoroughly and regularly cleaning feeders. Soak feeders and all parts for at least ten minutes in a ten percent bleach solution (one part bleach to nine parts warm water). Scrub, thoroughly rinse, and dry completely before re-using. This should be repeated at least every couple of weeks as regular feeder maintenance.

Thompson also recommended reducing the number of feeders, spreading them out, and using feeders that accommodate fewer birds (using tube feeders rather than platform feeders.) Avoid using wood feeders because they’re difficult to keep clean. Metal, glass or plastic tube feeders, that don’t have flat surfaces where droppings, fungus or other dirt can collect and spread disease, are better. Make sure any feeders used allow rain and melting snow to drain easily.

Finally, keep areas under feeders clean of excess spilled seed to deter rats and other pests, and to minimize fungal growth.

Reports of dead birds in Washington can be made to the Dead Bird Reports line, 1-800-606-8768.

Time to ready nest boxes for Spring.
Spring may officially be several weeks off, but now is the time to get your bird nest boxes cleaned out and ready for new, incoming occupants.

Get nest boxes ready for new occupants

Spring may officially be several weeks off, but now is the time to get your bird nest boxes cleaned out and ready for new, incoming occupants.

Many backyard sanctuary managers who use nest boxes leave them up year-round and leave nesting materials in them through the winter, when some birds will use them as nightime roost sites.

But migrating birds that use cavities for nesting, like bluebirds, swallows and wrens, will be returning next month and they prefer clean quarters to follow their instincts to build their own nests.

All nest boxes attract insects – mites, lice, fleas, flies, hornets, spiders and more. In small numbers they are relatively harmless to birds, but in larger numbers they can cause injuries and even fatalities to young birds.

Inspect all nest boxes to clean out insects and also to remove the old nesting material. Although some diligent and industrious birds will remove old nesting material before building their own particular nest, many more will just build on top of an old nest. That kind of layering can raise the nest dangerously close to the entrance hole where predators might reach eggs or young.

Your inspection may turn up dead nestlings or infertile eggs, which of course should also be removed. Be sure to use protective gloves, maybe even a dust mask, and dispose of everything you find in nest boxes away from the site to avoid smells that can attract predators.

Nest box maintenance includes tightening screws, loosening lag bolts, unblocking drainage holes, and generally making sure everything is secure and working right.

If you find a nest box in your collection that year after year goes unused, consider relocating it. It might not be in the appropriate habitat or suitable height location for the species it’s built for, or perhaps it’s in the right place but is not built correctly. Check the entrance hole size, overall size dimensions, and other factors that are important to, and different for, various species of nest-box-using birds. Details are available at http://wdfw.wa.gov/living/projects/nestboxes/index.html .

If the same nest box turns up dead nestlings or infertile eggs more than once, consider relocation to avoid competitors or predators, or remodeling to protect the species using the box. A predator block – just a one-inch thick piece of wood drilled with the appropriate size hole – mounted over the entrance hole to create a short tunnel into the nest, can deter starlings, raccoons, or squirrels that have chewed the original hole bigger.

Another improvement is to remove any perch post projecting out from the front of a nest box. Our native cavity-nesting birds don’t need these perches but they are used by more aggressive non-native birds to harass nesting birds.

If you often have earlier-arriving starlings or English house sparrows dominating your nest box site, you may want to plug the entrance hole until later this spring when martins or swallows or other native species arrive. Small paper cups and other such plugs work well. Remember to remove the plug as soon as you see your “target” species return to the area, or when you otherwise learn of its return to your area. (Online birding chat groups can be a good source of news about migratory bird movements.)

If you watch a nest box closely enough this spring to know when birds have finished raising a brood, you can clean out the box again to encourage another pair to use it or the same pair to nest again. Just don’t bother an obviously occupied nest box.

Flickers at feeding platform
Studies show that only small pockets of bird populations occasionally benefit from supplemental feeding under extreme and persistent weather conditions.

Winter wildlife feeding makes us feel good

When the weather outside is frightful, many of us find feeding birds and other wildlife quite delightful.

But does it help wildlife?

Studies show that only small pockets of bird populations occasionally benefit from supplemental feeding under extreme and persistent weather conditions.p

Most birds do not depend solely on feeders in their foraging, many obtaining only up to one-fifth of their nutrition at feeders. Feeding can’t replace natural habitat needed for winter cover and spring nesting and rearing. And poorly maintained feeding stations can actually harm birds by spreading disease.

Research also shows that the most readily-available feed – grains like whole corn and oats or seeds like sunflower and millet – are not easily digested by wild ungulates like deer or elk. It can take several weeks for deer to adjust to the change from natural browse plants to an artificial diet, and if they don't have enough fat reserves to carry them through the adjustment period, they can die of starvation even with a belly full of undigestible feed.

The best way to help any wild birds or mammals survive a severe winter is to maintain high-quality habitat plantings year-round. Wildlife that goes into the winter in good condition is most able to survive deep snow, ice and cold temperatures. Even in well-functioning natural ecosystems, however, some animals succumb during winter months. The winter season has always kept wildlife populations in balance with available habitat.

Another way to help wild animals in winter is to avoid disturbing them. Animals must conserve their energy to survive winter conditions, and human disturbance causes them to move about. Keep cats and dogs confined, and slow down when traveling in motor vehicles through deer and elk habitat.

The main benefit of wildlife feeding is that it provides a direct, intimate view of wild animals for more than 50 million Americans who provide backyard feeding stations of some kind.

Experts in Cornell University Lab of Ornithology’s Project FeederWatch, which collects winter bird feeder use data from volunteers across the country, say most bird feeding does neither significant good nor significant damage. It’s something we do for ourselves, they say, and because it has a lot of educational value, the program continues in its 24th season with more than15,000 participants.

Up close and personal encounters with wildlife can and do trigger lifelong interest in and compassion for wildlife, desire to learn more, and ultimately the “bigger picture” understanding of the need to maintain and enhance year-round wildlife habitat.

Certainly some of the charter members of the Washington Department of Fish and Wildlife (WDFW) Backyard Wildlife Sanctuary program began with feeding alone and quickly expanded their efforts to landscaping for wildlife.

If you choose to feed birds, please keep the following in mind:

  • Use tube feeders for birds to reduce accumulations of droppings that can spread disease; if you use platform feeders, provide only a day’s worth of seed at a time.
  • Clean and disinfect feeders at least once a month with a solution of one part bleach to nine parts warm water; rinse and dry disinfected feeders thoroughly before re-filling.
  • Pick up spilled food or waste from the ground at least once a week.
  • Discard feed that is wet, looks or smells moldy, has fungus on it or has been contaminated by rodents.
  • Locate feeders where there is no immediate cover for cats to wait in ambush, but close enough to cover to allow birds to escape natural predators like hawks.

If you think you want to feed deer or other wild ungulates, think first about the following:

  • Feeding should start early in the winter season to allow animals’ digestive systems to adapt, and continue through March or April when natural browse is again abundant.
  • The best artificial deer feed is a pelleted ration of about 50 percent alfalfa and 50 percent barley and corn; elk are able to transition fairly quickly to alfalfa hay.
  • Once a diet shift has occurred, one white-tailed deer can consume three to four pounds of pelleted feed daily; in just four months, one deer could consume almost 500 pounds of feed.
  • Concentrating deer and elk at a feeder can create problems by making the animals more vulnerable to disease, predation and poaching.
  • If feeding areas draw animals across well-traveled roads, they are more likely to present a safety hazard and be hit by motor vehicles.
  • Deer and elk drawn to artificial feed also can damage nearby agricultural areas, trees, or landscaping, especially if the artificial feed supply is not maintained through the winter.
  • WDFW feeds some deer and elk on public lands only where needed to prevent agricultural damage to adjacent property (ie. Oak Creek) or where natural winter range has been destroyed by wildfires or other natural disasters (ie. Mount St. Helens).

We’re counting on you counting birds

White-crowned sparrow
The birds you watch in your backyard this winter can be part of two scientific data bases that count on you counting them.

The birds you watch in your backyard this winter can be part of two scientific data bases that count on you counting them.

The 112th annual Audubon Society Christmas Bird Count (CBC) is the longest running “citizen science” survey in the world. Between December 14 and Jan. 5, 2012, tens of thousands of volunteers throughout North America will add a new layer to more than a century of data.

CBC volunteers follow specified routes through a designated 15-mile (24-km) diameter circle, counting every bird they see or hear all day. The data collected by observers allow biologists to study the long-term health and status of bird populations across the continent.

If you live within a CBC circle, you can arrange in advance to count the birds by species at your backyard habitat provisions or feeders and submit those data to your local compiler.

Counts are being coordinated in several communities across Washington, from Anacortes to Yakima. Some counts may charge small fees ($5 or less) to cover the cost of materials for compilers, the annual CBC summary, and maintenance of the CBC website and database. You can find counts by community and date, and learn who to contact for data compilation, at the Washington Ornithological Society website at http://www.wos.org/cbc.html .

Even easier for backyard birders is the Great Backyard Bird Count (GBBC), and the 15th annual will be conducted February 17-20, 2012.

GBBC participants count birds anywhere for as little or as long as they wish during the four-day period. They tally the highest number of birds of each species seen together at any one time. To report their counts, they fill out an online checklist at the GBBC website, http://www.birdsource.org/gbbc/.

As this count progresses, anyone with Internet access can explore what is being reported from their own towns or anywhere in the United States and Canada. They can also see how this year's numbers compare with those from previous years. Participants may also send in photographs of the birds they see for the GBBC’s on-line photo gallery.

“Both of these bird counts are good ways to learn more about the birds you see in your backyard or neighborhood or local wildlife area,” said Washington Department of Fish and Wildlife (WDFW) biologist Christopher Anderson of Mill Creek. “They’re also a great way to add to our collective knowledge about birds.”

Anderson noted that this year CBC participants may have a chance to add an uncommon species to their counts – snowy owls are in Washington earlier than usual and possibly in greater numbers than usual.

These big white owls, with round heads and big yellow eyes, breed on northern tundras and migrate just into the northern tier of the country when food becomes scarce. WDFW staff have reported individual owls in Stevens County, just south of Colville, in Lincoln County north of Davenport, in Skagit County near Puget Sound, and other places.

“We seem to be having bit of an irruption year for snowy owls,” Anderson said. “A sudden increase of migrating individuals of any given species is usually based on changes in food sources or weather conditions. The last one was the winter of 2005-2006 if I remember right.”

Anderson noted that current reports of snowy owls across the country are being mapped on-line by birders at http://bit.ly/vBWj73. Information about snowy owls is available at http://www.birdweb.org/birdweb/bird/snowy_owl and http://www.owlpages.com/owls.php?genus=Bubo&species=scandiacus .

“It’s a great time to see this cool diurnal arctic owl,” he said. “Whatever birds you see or help count this winter, just remember to watch carefully from a distance and avoid disturbing them.”

Black bears raiding a birdfeeder.
Backyard bird feeders may provide great window-view entertainment during the cold fall and winter months, but they can mean trouble, from raiding bears to the spread of bird diseases.

From bears to disease,backyard bird feeders can mean trouble

Backyard bird feeders may provide great window-view entertainment during the cold fall and winter months, but they can mean trouble, from raiding bears to the spread of bird diseases.

Black bears have become notorious raiders of backyard bird feeding stations in Washington, especially where both people and bears are most dense. Black bears are abundant in forested habitat, so the suburban and even urban areas of the north Puget Sound and Olympic Peninsula regions of the state have the most chronic problems.

Washington Department of Fish and Wildlife (WDFW) officials explain that hungry bears are looking for easy meals to fatten up before they go into winter dens. When a bear becomes conditioned to food near humans, whether from a bird feeder or a garbage can, it can be dangerous. WDFW enforcement officers attempt to capture and relocate bears, but too often there’s nowhere to safely release a conditioned, problem animal and they are sometimes euthanized.

Black bears usually go into winter dens by November, but that can vary depending on weather conditions. Availability of food can also be a trigger for winter denning, so it’s possible that feeders and unsecured garbage cans could change bears’ natural behavior.

“Backyard bird feeding can be recreational, even educational, for us,” said WDFW wildlife biologist Christopher Anderson, “but it isn’t critical for wintering birds. They can and do find natural sources of food throughout the winter, especially if you’ve landscaped your property with shrubs and trees that produce seeds, nuts or fruits. But if you really want to feed birds to be able to watch them more easily, and if bears are a potential problem in your area, hold off putting the feeders up until Thanksgiving or after.”

Backyard feeders can also concentrate birds so they attract both wild and domestic predators. Depending on feeder placement and available escape cover, birds can become more vulnerable to ambushes by hawks or cats.

But even more troublesome than bears or cats, however, can be the spread of bird diseases at backyard feeding stations that are not meticulously maintained.

The most common is salmonellosis, a usually fatal bird disease caused by the salmonella bacteria that is transmitted through bird droppings at feeders. The disease afflicts species such as finches, grosbeaks and pine siskins that flock together in large numbers at feeders.

The first indication of the disease is often a seemingly tame bird on or near a feeder. The birds become very lethargic, fluff out their feathers, and are easy to approach, but there is very little that can be done to treat them.

It’s possible, although uncommon, for people to become sick from the salmonella bacteria through direct contact with infected birds, bird droppings, or through pet cats that catch sick birds. People who handle birds, bird feeders or bird baths should wear gloves and wash their hands thoroughly afterwards.

In Washington, other bird diseases that may be seen at backyard feeding stations include avian pox -- a viral disease that causes wartlike growths on unfeathered parts of birds’ faces, legs, and feet; aspergillosis -- a disease caused by a fungal mold that grows on damp feed or soil in or around the feeder; and trichomoniasis -- a disease caused by small parasites that is mostly found in doves and pigeons and may often spread to local birds of prey when they eat infected birds.

When disease is noted or suspected in local birds, feeders should be taken down for two to three weeks or more to reduce concentration of sick birds at feeders and curb spread of the illness. Clean feeders with a ten percent bleach solution (one part bleach to nine parts warm water). Soak feeders and all parts for at least 10 minutes. Scrub, thoroughly rinse, and dry completely before re-using. This should be repeated every couple of weeks as regular feeder maintenance.

Avoid using wood feeders because they’re difficult to keep clean. Metal, glass or plastic tube feeders, that don’t have flat surfaces where droppings, fungus or other dirt can collect and spread disease, are better. Make sure any feeders used allow rain and melting snow to drain easily. Finally, keep areas under feeders clean of excess spilled seed to deter rats and other pests, and to minimize fungal growth.

Americans’ most popular pet is also one of the most harmful to backyard wildlife.
Americans’ most popular pet is also one of the most harmful to backyard wildlife.

Cats and bats are more than just scary
This popular story is recycled from a three-year-old “Crossing Paths” edition.)

It was almost like a scene out of Halloween movie.

Backyard wildlife enthusiasts in western Washington reported finding six dead bats scattered on their porch and lawn.

Washington Department of Fish and Wildlife (WDFW) biologist Chris Anderson, based in the North Puget Sound region office in Mill Creek, explored the possibilities with the concerned reporting party.

The neighborhood was full of birds, bats, raccoons, squirrels, and cats, Anderson learned. When he first suggested there might be a situation that allowed a house cat – a potentially very effective predator – to take advantage of the local bats, there wasn’t initially much belief.

But when the property owners set up a night watch to learn what was happening, the results were as educational as scary….

They keyed in on a locally-familiar, free-ranging, homeless cat hiding by their flowering yucca plant.

Yuccas flower both day and night and are great nectar sources for butterflies and moths. They hadn’t realized until that night how attractive yucca nectar is to night-flying moths, and they watched many coming in to feed.

And then nature’s food chain displayed itself.

The feeding moths attracted hungry bats, swooping in to grab a meal of moth. The feeding bats, in turn, were killed by the quietly waiting cat.

With two more dead bats left by the cat on their lawn, two things became clear: the cat wasn’t necessarily hunting out of hunger, and for the sake of the neighborhood’s wildlife, it needed to be removed from the area.

The situation was relayed to neighbors, some who may have been feeding the homeless but tame cat, and then it was taken to a shelter for care and adoption by a cat lover who will keep it indoors.

“These folks gave both the bats and the stray cat itself a break,” Anderson said. “It was really the best option. And the situation helped them realize that free-ranging domestic cats are deadly to wildlife.”

Americans’ most popular pet is also one of the most harmful to backyard wildlife.

Our 84 million or so pet cats, plus perhaps at least that many homeless feral cats, kill billions of birds, small mammals and other wildlife each year.

Anderson is a cat owner who believes we can have both in our lives.

“Research shows that spending time with pets and spending time watching wildlife both lower stress levels,” Anderson said. “So why not have both?”

Anderson walks his cat outdoors on a leash with a harness, but otherwise keeps it indoors. “He didn’t like the leash when we first adopted him,” he said, “but he adjusted to it and my two dogs. Now my cat enjoys the outdoors safely, both for him and for wildlife.”

The lives of free-roaming pet cats are often cut short by vehicle collisions, disease, poisoning, parasites, territorial fighting, and predation. According to the Humane Society, indoor cats and those confined or controlled when outdoors can average at least three times the lifespan of free-ranging cats.

Wildlife definitely benefits from keeping cats indoors and under control when outdoors.

Extensive studies of the feeding habits of free-roaming domestic cats have been conducted over the last 55 years throughout the world. These studies show the number and types of animals killed by cats varies greatly, depending on the individual cats, the time of year, and availability of prey. Roughly 60 to 70 percent of the wildlife cats kill are small mammals; 20 to 30 percent are birds; and up to 10 percent are amphibians, reptiles, and insects.

Some free-roaming domestic cats kill more than 100 animals each year. One well-fed cat that roamed a wildlife experiment station was recorded to have killed more than 1,600 animals (mostly small mammals) over 18 months. Rural cats take more prey than suburban or urban cats. Birds that nest or feed on the ground, such as California quail, are the most susceptible to cat predation, as are nestlings and fledglings of many other bird species.

Well-fed cats kill birds and other wildlife because the hunting instinct is independent of the urge to eat. In one study, six cats were presented with a live small rat while eating their preferred food. All six cats stopped eating the food, killed the rat, and then resumed eating the food.

Other studies have shown that bells on collars are not effective in preventing cats from killing birds or other wildlife. Birds do not necessarily associate the sound of a bell with danger, and cats with bells can learn to silently stalk their prey. Even if the bell on the collar rings, it may ring too late, and bells offer no protection for helpless nestlings and fledglings.

Wildlife rehabilitation centers report that most small animals injured by cats die. Cats carry many types of bacteria and viruses in their mouths, some of which can be transmitted to their victims. Even if treatment is administered immediately, only about 20 percent of these patients survive the ordeal. A victim that looks perfectly healthy may die from internal hemorrhaging or injury to vital organs.

Anderson noted that the idea of trapping, spaying/neutering, releasing, and leaving food out for feral cats is misguided.

Cats are solitary animals, but groups of feral cats often form around an artificial feeding source, such as garbage dumps or food put out for them. These populations can grow very quickly, even if most are spayed or neutered -- it only takes one intact cat to start multiplying!

These feral cat colonies can have significant impacts on wildlife populations and feeding doesn’t prevent them from following predatory instincts. Feral cat colonies can also cause significant health risks to other cats and humans.

“Cats are good pets but lousy outdoor companions,” Anderson said. “It’s a cat’s nature to stalk prey, even when they’re well fed. We cat owners need to take responsibility for them and keep our wildlife safe.”

Standing dead and dying trees, called “snags” or “wildlife trees,” are important for wildlife in both natural and landscaped settings.
Oregon-grape, one of the many native plants that can provide wildlife habitat.

Now is the time to add shrubs and trees to your landscape

There’s no better time than early autumn to add habitat-providing trees and shrubs to your Backyard Wildlife Sanctuary landscape.

Planting in fall gives larger vegetation a head start on root development before the ground freezes and root systems go dormant for the winter. By next spring, these newcomers will be ready to take off, producing food and providing shelter for many species of wildlife.

Fall is also the time when many plant nurseries clear out stock, so you can often take advantage of big price discounts. Before taking in those fall sales, however, think about your available space and what you need or want to change or add.

Does your present landscape provide maximum food, cover, and safe travel corridors for wildlife? Are there unused lawn areas that could be planted with trees and shrubs? What areas have low diversity and need a better mix of wildlife-friendly plants? Are there solitary trees that could have shrubs and groundcover planted around them? Where would a screen of plantings, such as a tall hedge of deciduous and evergreen shrubs, improve outdoor privacy?

The Washington Department of Fish and Wildlife (WDFW) recommends using local native trees and shrubs in your landscape when possible. That’s because some of the best habitat for native wildlife includes plants that have evolved and occur naturally in your area. Native plants are more closely matched to local soils, climate and wildlife. They will be better, in the long run, at providing the right kinds of food, shelter and diversity needed by wildlife.

An added bonus of using native plants is that they typically need less maintenance and less water than non-natives.

While some native plants are readily available, others may be difficult to find. Check with your local plant nurseries, Washington State University Cooperative Extension (http://ext.wsu.edu/) which publishes a nursery guide including native plants sources, or Washington Native Plant Society (1-888-288-8022 or http://www.wnps.org.)

Serviceberry, oceanspray, ninebark, dogwood, currant, huckleberry, Oregon-grape, willow, vine maple, sumac, aspen, and juniper are among the many native species that can provide wildlife habitat of one kind or another in your landscape.

When it is not possible to use native plants, choose plants adapted to local site conditions that will provide seeds, berries, nectar (flowers), and good cover. Avoid sterile varieties (those that do not produce fruits of seeds).

Pay attention to sun, water, and soil needs of each tree and shrub species and place them in your yard where they will best flourish and not quickly outgrow the space. Most plants are fairly tolerant but prefer certain conditions. Consider height at maturity and other features such as fall color, showy flowers, aroma, or unique leaf shape.

Keep in mind how plants aid in energy conservation and comfort by letting in winter sun, protecting from prevailing winter winds, and shading the summer heat. Evergreens give winter protection for you and wildlife but will block the sun. Many deciduous trees have good food for wildlife and allow in winter warmth; they do not protect from winter winds.

Note any special problems some plants might have, such as weak wood, messy fruit, over patios, or invasive roots.

You will probably find more than one plant that fits the needs of a certain spot. Cost, availability, and personal preferences for unique features may influence your final selections.

WDFW’s book by North Puget Sound regional wildlife biologist Russell Link, “Landscaping for Wildlife in the Pacific Northwest,” (http://wdfw.wa.gov/living/book/index.html) is an excellent source of more detailed information about trees and shrubs in your backyard landscape.

Standing dead and dying trees, called “snags” or “wildlife trees,” are important for wildlife in both natural and landscaped settings.
Standing dead and dying trees, called “snags” or “wildlife trees,” are important for wildlife in both natural and landscaped settings.

Better dead than alive?

As strange as it seems, some trees can actually provide more habitat for wildlife when they’re dead than when they’re alive.

Standing dead and dying trees, called “snags” or “wildlife trees,” are important for wildlife in both natural and landscaped settings.  

Birds, small mammals, and other wildlife use snags for nests, nurseries, storage areas, foraging, roosting, and perching. Live trees with snag-like features, such as hollow trunks, excavated cavities, and dead branches can provide similar wildlife value.

Snags occurring along streams eventually fall into the water, adding important woody debris habitat for fish and other aquatic life.

Snags can attract wildlife species to your property that you might not otherwise see.

More than 100 species of our birds, mammals, reptiles, and amphibians need snags for nesting, roosting, and denning.  Hollow snags and large knot-holes are used by Douglas squirrels, northern flying squirrels, martens, porcupines, raccoons, and even black bears. Several species of owls and woodpeckers also use large cavities. Bluebirds, chickadees, swallows, wrens and other songbirds use smaller cavities. Brown creepers, nuthatches, bats, lizards, and mourning cloak butterflies will roost behind loose bark and bark slits for winter warmth and shelter.

Some 45 of our wildlife species forage for food in snags, which are often loaded with insects. Woodpeckers, sapsuckers, flickers, nuthatches, and a myriad of other insectivorous species regularly make snags their dining rooms. Mice, squirrels, jays, crows and other wildlife use snags more like kitchens, for food storage areas.  

Some snags make ideal hunting perches for hawks, eagles, and owls.  The more open resting perches that snags provide are preferred by swallows, band-tailed pigeons, mourning doves and other colonial birds. And of course the resonating surfaces of some snags are perfect for woodpeckers to announce their presence with their hammering bills during courtship season.  

Snags of both deciduous and coniferous trees are used by wildlife. The most favored snag species east of the Cascades are ponderosa pine, western larch, quaking aspen, and paper birch; west of the Cascades, Douglas fir, western red cedar, big-leaf maple and cottonwood snags are highly used. Softwood trees such as fir tend to make better food foraging trees, while hardwood trees are sometimes better for nesting cavities.

Unfortunately, many of these dead or dying trees are cut down without much thought to their wildlife value and the management options that can safely prolong their existence.

Of course if not managed properly, snags can pose a risk to people and structures. If a dead or dying tree threatens something that can be moved, such as a swing set or patio furniture, consider moving those items before cutting the tree down. An alternative to eliminating the entire tree is to remove only the dangerous sections.

Consulting with a certified arborist experienced in wildlife snags is recommended. These professionals can determine what part of a tree is a hazard and provide management options to reduce or eliminate any risk. Remaining parts can be removed over time. Often, once the unsafe limbs or portions of the trunk have been removed, the tree is safe.

Retain live trees and tall shrubs near a snag to protect it from wind and provide a more complete environment for wildlife. In urban areas, tall snags are best located away from high activity areas, where they won’t pose a hazard if they fall. Trees that lean away or are downhill from structures and other areas of human activity present little or no risk.

When a tree must be cut down, maximize its habitat value by placing as much of the debris as possible near the area where the tree was removed. In hot, dry areas, move the material into the shade of nearby trees or large shrubs.

You can create a snag from trees that are hazardous or problematic, like ones with forked tops or disease or invasive roots threatening a drainage or septic system, or individual trees in a group that needs thinning.  Like landscaping rocks and boulders, snags can add interesting, artistic angles to your property.

More information about snags, including details about how to safely create a snag, or enhance existing dead or dying trees, is available at http://wdfw.wa.gov/living/snags/.

Pacific Treefrog
Pacific Treefrog

Herps may be hiding in your backyard

Fourteen salamanders, 12 snakes, 10 frogs, 7 lizards, 3 toads, and 3 turtles – that’s how many different species of reptiles and amphibians, or herpetofauna (“herps”) occur in Washington.

Fortunately they’re not all in your backyard, but some of the most common and adaptable species might be, especially if you provide or live near the right habitat.

Herps are an essential part of the wildlife food chain, consuming lots of insects and sometimes being consumed by other animals. Amphibians (frogs, toads, salamanders) need wet habitats during at least part of their life cycle. Most herps are especially sensitive to pollution so they can be indicators of overall environmental degradation.

Relative to other groups of wildlife species, we’re still learning much about herps. That’s why the Washington Department of Fish and Wildlife (WDFW), in cooperation with the Washington Department of Natural Resources (DNR), Bureau of Land Management (BLM), and US Forest Service (USFS), helps maintain the “Washington Herp Atlas” at http://www1.dnr.wa.gov/nhp/refdesk/herp/. There you can find information on life history, habitat, status, threats, management concerns and distribution of herps.

You can also help add to the information known about these animals by submitting observation records to WDFW biologist Lori Salzer at 360-902-2482 or lori.salzer@dfw.wa.gov .

Many species tend to be nocturnal (more active at night), but many are also simply hidden from your view under rocks, logs or dense vegetation. Summer evenings may be when you spot an interesting herp in your backyard, or just simply hear them.

The sounds of our most widespread and common frog species are almost synonymous with summer evenings, although they’re actually audible almost year-round across most of the state. The male Pacific Treefrog (Pseudacris regilla) regularly sings a prolonged one note “kr-r-r-r-ek”, especially when it rains. During breeding season, which can start as early as mid-February in western Washington and run well into July in the mountains, their call is a two-syllable “rib-it, kreck-ek”, repeated rapidly and in such large concentrations that the loud chorusing can be heard far away, especially at night.

Pacific Treefrogs might better be referred to by their other common name, Pacific Chorus Frogs, since they tend to be found on the ground or in shrubs (not trees), calling in unison and in large groups. Although they’re mostly nocturnal, especially at low elevations, they are unmistakable when spotted during the day – they are our only frog with circular pads at the tips of their fingers and toes that adhere well to smooth surfaces. Adults are usually less than two inches in length, green or brown in color.

Pacific Treefrogs use a wide variety of habitats and persist even within urban and disturbed areas, except in the very driest parts of the Columbia Basin. They use almost any type of still or slow-flowing water for breeding, from the still water edges of rivers to children’s backyard wading pools.

The most widespread toad species in Washington is also frequently heard but you have to be within about 30 or 40 yards to appreciate its voice. The Western Toad’s mellow chirping or plinking sound is like the peeping of a chick, produced repeatedly day and night. Multiple males vocalizing at the same time can sound like a distant flock of Cackling Canada geese.

This is a medium-sized to large toad (two to five inches) with a blunt head and stout body, short legs, and “warty” brown or green skin. It occurs in a variety of habitats, from grasslands and prairies to forests, with breeding waters usually permanent wetlands, ponds, lakes and stillwater river channels. Although its range is wide, it has been declining. It is especially vulnerable to road traffic during adult movements to and from breeding sites in the spring, and dispersal of young toads away from breeding sites in the summer and fall.

A herp that has been introduced to the West is the American Bullfrog (Rana catesbeiana). Native to the eastern U.S., these large (six-inch) frogs were originally introduced over a century ago, primarily for harvest of their meaty legs but also because people liked hearing their booming “jug-o-rum” call. Until recently, Bullfrog tadpoles were sold in local nurseries for garden ponds. But when its negative impact on native herp species became known, (predation, competition and disease), the species was classified as an invasive exotic and regulations were enacted to prohibit transport.

Unfortunately, with natural dispersal Bullfrogs are virtually everywhere in Washington, active both day and night depending on temperature. They breed throughout the summer months and egg and tadpole development is very rapid. Because the tadpoles are unpalatable to fish, they are more visible than most of our native frog tadpoles. More information on bullfrogs and other non-native, prohibited herps is available on WDFW’s Aquatic Invasive Species webpage at http://wdfw.wa.gov/ais/.

Another common exotic herp is the Pond Slider or Red-Eared Slider, (Trachemys scripta), a three to 14-inch aquatic turtle with yellow streaks on a dark upper shell and a bright red blotch on each side of the head. Native to the eastern U.S., hatchling Pond Sliders were sold in pet stores nationwide until 1975 when it became illegal to sell any under four inches due to the ease of contracting salmonella from handling them. Those seen today are probably descended from released pets, although our climate may be poorly suited to large-scale Pond Slider reproduction.

The majority of Pond Sliders reported in Washington are escaped pets from urban areas in the Puget Sound and lower Columbia Gorge area where they compete with native turtles for food and basking sites. If you think you see a Pond Slider, confine it and look for an owner in your neighborhood.

The Painted Turtle (Chrysemys picta) is native to Washington, common on the east side of the state, and likely introduced over 50 years ago to the urban residential areas of the Puget Sound region. This 2-1/2 to 10-inch aquatic turtle has a dark colored upper shell, bright red markings on the lower shell, and yellow lines on the head, legs and tail. Painted turtles only stray from water to lay eggs and disperse, preferring habitats that have muddy sediments and lots of aquatic vegetation. They’re active during the day, basking on rocks, logs and shorelines, and sheltering under water at night. In eastern Washington, Painted turtles are just now laying eggs, so hatchlings may be seen in late summer or early fall.

Another backyard herp is the Long-toed Salamander (Ambystoma macrodactylum), commonly found just about everywhere in the state, including urban areas, except right on the coast and in the driest shrub-steppe habitats of the Columbia Basin. These salamanders are about two to three inches long, (not counting the tail of near equal length), dark gray or black with an irregular yellow, olive or green dorsal stripe, and blue or white speckling on the sides. The common name refers to an unusually long hind toe. They spend much of their lives underground, using spaces between rocks or where roots, rotting wood, or the tunnels of other animals allow easy access. While surface active in the spring, they seek refuge under decaying logs, loose bark, rocks and other structures that retain moisture.

Western Fence Lizards (Sceloporus occidentalis) are common in Washington, from the Blue Mountains of the southeast to the Puget Sound area in the northwest. It’s a medium-sized (two to three inches, not counting tail) gray, brown or brownish-black lizard with keeled, spiny scales and two rows of light and dark markings down the back. They are excellent climbers and will escape up trees or scamper around rock faces when approached. At night and when conditions are cool or rainy, they shelter under rocks and logs. A small number of lizard populations associated with upper beach driftwood in the Puget Sound region could be lost to bulkheading and bank stabilization projects with shoreline home site development.

Although little appreciated, Washington’s three garter snake species -- Common Garter Snake (Thamnophis sirtalis), Northwestern Garter Snake (Thamnophis ordinoides, andWestern Terrestrial Garter Snake (Thamnophis elegans) -- are beautiful snakes with many stunning color variations by region of the state. The most widespread is the Common Garter Snake, which in eastern Washington is black bodied with bright yellow dorsal and lateral stripes and distinct red blotches on the sides; in western Washington, red blotches may or may not be present and the stripe coloration may be yellow, green, turquoise or blue. These snakes are almost always found near water, especially in the summer, including wetlands, bogs, ponds, lakes, springs, creeks, and rivers. They are good swimmers and can hunt both on and below the water surface.

Basic Songbird Nest Box Design
Basic Songbird Nest Box Design
Woodworking Projects for Backyard Wildlife

Help native nesting birds by design

Is your swallow nest box being used by House sparrows?

Your purple martin house taken over by European starlings?

You may have design flaws in the housing you’ve provided that allows these aggressive, non-native birds to thrive and our native birds to decline.

Some ready-made bird houses may look cute but are not necessarily designed to keep the bullies of the bird world out.

Perches, for example, aren't needed by birds but attract house sparrows and starlings.

Design and construction of bird houses need to be species specific. The most important part is the entrance hole. If the hole is too small, the desired bird won’t be able to enter. If it’s too big (and this is more likely) undesirable wildlife – like non-native sparrows and starlings, and uninvited squirrels, can get in and harm, evict, or kill the desired bird.

As a rule, house sparrows can’t enter a nest box if the entrance hole is less than 1-1/8 inches in diameter. Starlings can’t enter if the hole is less than 1-1/2 inches in diameter.

Information in the Washington Department of Fish and Wildlife (WDFW) “Woodworking Projects for Backyard Wildlife,” available at http://wdfw.wa.gov/living/projects/, specifies entrance hole sizes to exclude these birds wherever possible. Even if you don’t want to make your own nest boxes, it’s a good resource for making better decisions when you purchase bird houses.

Bird houses often have to be maintained on a yearly basis to stick to these specs. You’ll need to patch or restore the entrance holes after squirrels or woodpeckers have tried to enlarge them. There are many ways to do this, from attaching wooden extensions or “donuts” over the holes to fortifying them with metal washers.

If you still have problems with aggressive non-native species even when you follow the standards, there are also design alternatives.

A diamond-shaped entrance hole that is no more than 7/8-inch deep and up to 3-1/2 inches wide, will exclude house sparrows and starlings. To accommodate the slightly bigger violet-green swallow, file down the area inside of the entry hole by just a quarter inch. You can see these specs at http://wdfw.wa.gov/living/projects/basic_songbird.html.

Anacortes bird enthusiast Gene Derig came up with that diamond design but recently told us about an even simpler way to accommodate and protect not only violet-green swallows, but also chickadees, nuthatches, and other native species.

“Try using a ¾-inch high slot configuration,” Gene said. “The slot is made by drilling three consecutive horizontal holes with a ¾-inch drill bit, and then just shaving out what’s left. It’s especially good for urban areas where there are more house sparrows.”

The purple martin is a species that could really use help with suitable nest sites within its range in western Washington, since its numbers seem to be declining. In fact, it’s a candidate for state protective listing, in part because of competition from sparrows and starlings.

WDFW biologist Chris Anderson notes that purple martins are colony nesters, but those attractive “multiple apartment complex” bird houses designed for them can be a problem in urban areas where starlings and house sparrows are numerous.

“A cluster of gourds drilled with holes seems to be much less preferred by starlings and house sparrows and the martins love them,” Anderson said.

Another way to help is to be more strategic with placement of bird nest boxes.

Martins, like all swallows, feed on insects, mostly on the wing, often over water where insects concentrate. Hanging a gourd collection over water makes it that much more enticing to martins and less inviting to sparrows and starlings.

Sparrows and starlings usually won't nest within ten feet of the ground. Placing nest boxes four to five feet off the ground and in brushy areas will discourage these birds, and will readily be used by many native species, from bluebirds to wrens. Nest boxes at this height, however, are vulnerable to predators such as cats.

If you want to get rid of house sparrows or European starlings nesting in a bird house, it is legal to remove their nests and destroy the eggs. Unlike most birds, these non-native, introduced species are not protected by state or federal law. Nests may have to be removed five to six times before sparrows or starlings finally abandon the house.

Sometimes the best thing to do if your area is plagued by starlings or house sparrows, and you can’t actively manage them, is to simply not use bird nest boxes at all.

There are many other resources to help you address bird house issues in addition to WDFW’s “Living With Wildlife” webpages. Some of the best information is available on the Sialis website, developed for people interested in helping bluebirds (which are in the genus Sialia) and other native cavity-nesting birds. For starling problems, see http://www.sialis.org/starlingbio.htm and for House sparrow problems see http://www.sialis.org/hosp.htm.

Not all Spring babies are welcome

It’s wildlife reproduction time, and depending on the species, that can mean too much of a good thing for even the most wildlife-friendly homeowner.

Skunks and raccoons are the most common “nuisances” reported to Washington Department of Fish and Wildlife (WDFW) offices every spring. As these animals find crawl spaces, outbuildings, and other nooks and crannies to set up housekeeping for their babies to come, homeowners fear potentially nasty encounters with pets or children.

Squirrels, rabbits, moles, marmots, bats, snakes, and starlings are among the other wildlife species preparing to raise families that are potential nuisances around human homes.

If some of these new families are not what you had in mind for your Backyard Wildlife Sanctuary, think about what’s attracting them and remove those attractants as soon as possible to avoid problems.

The number one attraction for females of many species at this time of year is a warm, dry, easily defended area that makes a good den or nest. Close up spaces, including basement window wells, areas under porches and decks, garage and shed entries of even the smallest dimensions, roofing gaps, uncapped chimneys and vents, and attic rafters.

A close second for lots of wildlife is an easy food source.

  • Keep pet food and water and garbage inside.
  • Fence gardens and secure compost piles.
  • Clean up feed spilled on the ground from bird feeders, or discontinue feeding altogether for now.
  • Pick up fruit that falls off trees

If it’s too late for these preventive steps and animals are already in place and causing problems, you may need to remove them. If you want to attempt it yourself, check out “Evicting Animals from Buildings” in WDFW’s “Living With Wildlife” series on the website at http://wdfw.wa.gov/living/nuisance/evicting.html.

If you’d rather hire someone to take care of the problem, any WDFW office can refer you to a Nuisance Wildlife Control Operator (NWCO). Although they must be licensed through WDFW, and conform to its regulations, they are not state employees. They operate as private enterprises and set their own fees.

Under the authority of their WDFW permit, NWCOs can trap, capture, and transport “classified” (protected) species like raccoons, opossums, skunks, and other wildlife year-round. (Both native deer mice and non-native house mice and Old World rats are “unclassified” or unprotected species that can be trapped by anyone at any time.) For more information, see http://wdfw.wa.gov/living/nuisance/damage_control.html.

Planting trees

April 2011

Plant a tree for wildlife – and the earth – this month

April is the month to celebrate trees and the earth in general.

The second Wednesday, April 13 this year, is when Washington state celebrates Arbor Day. National Arbor Day is officially celebrated the last Friday of the month, April 29 this year.

April 22 is Earth Day internationally, this year with “A Billion Acts of Green” campaign, including the tree-planting “Canopy Project,” that is documenting efforts to reduce carbon emissions and support sustainability.

Washington Department of Fish and Wildlife’s (WDFW) Backyard Wildlife Sanctuary managers, and anyone else interested in Washington’s wildlife, are encouraged to celebrate both by planting a tree for wildlife.

Many of Washington’s native tree species provide nesting sites, roosting spaces, escape cover, and food for a diversity of native mammals, birds, reptiles and amphibians, and invertebrates like butterflies and moths.

Big-leaf maple (Acer macrophyllum) is a fast-growing tree suited for large landscapes that provides homes for cavity-nesting birds and food for insectivorous birds like woodpeckers and nuthatches.

Douglas maple (Acer glabrum douglassii) is a small tree used for its seeds by grosbeaks, quail and grouse, for its twigs and bark by deer and beavers, and as a larval host for some moth species.

Vine maple (Acer circinatum) is best suited for westside landscapes where it grows naturally in groups as large understory shrubs or small trees. It’s a larvae plant for brown tissue and polyphemus moths, a good nectar source for bees, and seed-producer for a variety of birds.

Oregon white oak or “Garry oak” (Quercus garryana) is a thick-limbed, long-lived tree that is Washington’s only native oak. Like all oaks, it produces acorns loved by everything from Clark’s nutcrackers to tree squirrels, and at maturity they often provide cavities for nesting and roosting by both birds and mammals.

Pacific dogwood (Cornus nutallii) has large, creamy-white, showy flowers eaten by spring azure butterfly larvae. A diversity of birds, including bluebirds , sapsuckers, white-crowned and song sparrows, tree swallows, towhees, and vireos eat its fruit.

Cascara (Rhamnus purshiana) is a native small tree or tall shrub that grows well in disturbed sites. Its berries are eaten by grosbeaks, grouse, jays, robins and tanagers, as well as bears, foxes, coyotes and raccoons.

Native birches (Betula spp.) are hardy clump-growers to plant far from drain pipes or foundations, but they produce lots of wildlife habitat: seeds for juncos, siskins and other birds; insects for kinglets, warblers and other birds; bark for nesting material; leaves for mourning cloak and swallowtail butterfly larvae; twigs for elk, deer and small mammals; cavities for birds and other wildlife.

Native hawthorns (Crataegus spp.) are more shrub-like than tree, with densities that often provide good escape cover for songbirds. Berries are favored by robins, waxwings, wood ducks, turkeys, black bears, coyotes and foxes, to name a few.

Native pines (Pinus spp.), which can be fast-growing large trees best suited for larger properties, provide nesting sites for many songbirds and seeds for, among others,  crossbills, mourning doves, jays, finches, siskins, and chipmunks.

Douglas-fir (Pseudotsuga menziesii) grows quickly with a dense screen of soft needles that are used by silver-spotted tiger moth larvae, among others; its seeds are eaten by grouse and many songbirds, its associated insects are eaten by brown creepers and woodpeckers, its twigs are browsed by deer and elk; at maturity its cavities harbor flying squirrels and other animals.

Western hemlock (Tsuga heterophylla), Washington’s state tree, is favored by elk and deer for its delicate feathery foliage, and  juncos, siskins, chickadees and squirrels for its seeds.

Lots more detail about these and many other trees for wildlife is available in the book by WDFW wildlife biologist Russell Link, “Landscaping for Wildlife in the Pacific Northwest” ( http://wdfw.wa.gov/living/book/index.html .)

Certified arborists are excellent professional resources on tree installation, care, and maintenance and can be found through the Pacific Northwest chapter of the International Society of Arboriculture (http://www.pnwisa.org/.)

Plan your garden for wildlife now

Backyard Wildlife Sancturay Program

Gardeners have been daydreaming over seed catalogues since New Year’s, but with actual Spring finally within sight now, it’s time to place orders and make those dreams come true.

Those who also garden for wildlife will want to keep the birds, bees, butterflies, and other animals in mind when making those seed and plant selections.

Lots of varieties of annuals and perennials, plus garden vegetables, can provide food for wildlife with nectar-producing blooms and/or attract pollinating insects that become part of the food chain for others.

So how do you choose from all those enticing catalogue pictures and listings?

Washington Department of Fish and Wildlife (WDFW) biologists recommend using local native plants when you can, or non-natives if they’re not invasive in your local area.

“Don’t choose hybrids with double flowers because the flower structure may prevent flying insects from gaining access to nectar or may even have nectar-production bred out,” said WDFW’s North Puget Sound regional wildlife program manager Russell Link.

WDFW’s Backyard Wildlife Sanctuary program information (available at http://wdfw.wa.gov/living/backyard/ ) includes some specifics about plant choice to benefit wildlife, like hummingbirds and butterflies. These include both local native and non-native plant species, but natives are usually best.

Links says plants that are native to local habitat in Washington are best suited for our soils and climate so they usually grow more easily. By nature of being native, they have the potential to be truly “sustainable”.

The appropriate native plant usually require less care, especially watering, once they are established. And most important to wildlife enthusiasts, many native plants are more readily used by the native wildlife with which they evolved.

Plant and seed catalogue companies from across the country may include species “adapted to the Northwest,” but remember that is not the same as “native to the Northwest.”

Thanks to increasing interest in “sustainability,” sources of native plants and seeds are increasing in Washington. The Washington Native Plant Society (WNPS) provides a list of nurseries by county that sell native plants and seeds (see http://www.wnps.org/landscaping/nurserylist.html.)

Whether you go native or use non-invasive exotics, keep those pollinators in mind.

“I buy a lot of “six packs” from a local nursery,” Link said, “and when shopping, I’ll give the flats of flowers a little shove to see what flies off. Some flowers, like Sweet allysum, will produce a flurry of of flying pollinators.”  

Link also notes that most vegetables are pollinated by flying insects.

“I grow scarlet runner beans because they have attractive red flowers, are tasty, and attract bumblebees and hummingbirds,” he said.

Some plants pollinated by insects specifically attract night-flying moths that provide food for bats, including Sweet William, Fireweed, Honeysuckle, Bee balm, Mock-orange and Yucca. Bats Northwest has more information on moth-friendly plant species at http://www.batsnorthwest.org/attracting_insects.html .

Link’s book, “Landscaping for Wildlife in the Pacific Northwest,” is a good source of further information on plant choices for the wildlife garden. For more details on how to purchase this reference, see http://wdfw.wa.gov/living/book/index.html .

Backyard Wildlife Sancturay Program
House finches

Count birds this month and save dates for coming events

Backyard birdwatchers can help researchers create a real-time snapshot of how birds are surviving the winter by participating in the 14th annual Great Backyard Bird Count (GBBC) Feb. 18-21.

The GBBC is always conducted in February to see where birds are just before spring migrations begin in March. Anyone can participate, from beginning bird watchers to experts. It takes as little as 15 minutes on one day, or you can count for as long as you like each of the four days. It doesn't matter whether you report five species coming to your backyard feeder or 75 species you see during a day's outing to a wildlife refuge. Tally the highest number of each species seen together at any one time, then report them through an Internet online checklist at http://www.birdsource.org/gbbc/.

As the count progresses, you can explore what’s being reported from your own town or anywhere in the United States and Canada. You can also see how this year's numbers compare with those from previous years.

The GBBC is led by the Cornell Lab of Ornithology and National Audubon Society, with Canadian partner Bird Studies Canada and sponsorship from Wild Birds Unlimited.

Many other on-the-ground, local wildlife events are coming up this spring that are worth marking on your calendar now.

  • February 26 – 27 is the 6th annual Port Susan Snow Goose and Birding Festival, sponsored by the Pilchuck Audubon Society, Stanwood Chamber of Commerce, Island County, Camano Island Chamber of Commerce and many others.

“10,000 by 2010” goal met in 25th year of WDFW Backyard Wildlife Sanctuary program

Backyard Wildlife Sancturay Program
Backyard Wildlife
Sanctuary Program

The Washington Department of Fish and Wildlife (WDFW) Backyard Wildlife Sanctuary program celebrated its 25th anniversary year by more than making a “10,000 by 2010” campaign goal.

By the end of 2010, an official total of 11,454 properties across the state were enrolled as Backyard Wildlife Sanctuaries. 

With the program’s emphasis on urban and suburban properties where habitat development and restoration is most needed, 89 percent of those properties (10,238) are in western Washington, where more of the state’s cities and towns lie in the Puget Sound area from Bellingham to Vancouver.

The other 11 percent (1,216) are in eastern Washington, mostly in the state’s second largest metropolitan area -- Spokane – with some in the Tri-Cities, Yakima and Wenatchee areas.

The “10,000 by 2010” campaign began in the summer of 2009, when the statewide total of properties enrolled was 8,507. The 10,000 mark was reached in April 2010 with enrollment of a property in Olympia.

The Backyard Wildlife Sanctuary program began in 1985 in WDFW’s North Puget Sound Region, based in Mill Creek, north of Seattle. It quickly expanded to the Spokane-based Eastern Region for statewide promotion of the program’s basic idea – wildlife stewardship begins at home, even and especially in urban settings.

With over 35,000 acres of wildlife habitat converted to housing and other development each year in Washington, the program is designed to help offset that loss by encouraging backyard landscaping to provide food and cover for wildlife.

Over the years the program has increased emphasis on development and maintenance of year-round habitat, preferably using low-maintenance, low-water-use native plants. Information on supplemental feeding of birds has increasingly focused on keeping feeders clean to avoid spreading disease among birds and locating feeders to minimize problems with predation by domestic cats and wild predators and birds flying into nearby windows.

The program not only enhances the urban environment for the benefit of wildlife, but it also helps increase opportunities for people to enjoy and learn about wildlife by providing information about best practices for attracting watchable wildlife to your home.

The latest (2006) U.S. Fish and Wildlife Service survey of wildlife associated recreation showed that 2.3 million Washington residents, or about 40 percent of the state’s population, actively watch wildlife.  Most of those – 1.9 million or 83 percent – watch wildlife “around home” (defined as within a mile of home.) About 1.5 million feed wildlife and about 360,000 maintain natural areas or plantings for wildlife.

If you’re currently one of the many thousands of Washington Backyard Wildlife Sanctuary managers, thank you for all you do to help wildlife on your property. We encourage you to talk to your neighbors about similarly helping wildlife on their property because the bigger the contiguous blocks of habitat, the better for wildlife and wildlife watching.

Be considerate when watching wildlife in winter

Trumpeter and tundra swans
Trumpeter and tundra swans

While winter can be a great season to watch wildlife, it’s also the time when we can most easily stress those subjects of our surveillance.

All of us, including our feathered and furred friends in the wild, use more energy to move and function in winter’s cold and snow. Unnecessary disturbance of animals that exist 24-7 in those conditions just depletes their energy reserves more quickly.

Washington Department of Fish and Wildlife (WDFW) wildlife biologist Christopher Anderson says minimizing impact to wild animals at this time can be critical to their survival.

“This is the lean season for wildlife,” Anderson said. “Little things can make a difference, like approaching animals too closely and causing them to flush or flee, often times in cold temperatures or through deep snow. You can avoid disturbing wildlife in that way by using your binoculars or scope and telephoto camera lens. Teach children to be respectful of wildlife and their need for space. And leave the dog at home, in the vehicle, or indoors if you’re watching on your own property.”

Some wild animals that winter in Washington are very opportunistic in their survival strategies. A well worn trail through the snow to a site where wildlife beds, roosts or dens will be readily used by predators, both wild and domestic. Food sources inadvertently left accessible -- like garbage, compost, pet food, or poorly placed bird feeders – may draw animals that prey upon winter concentrations of other species.

Feeding wildlife in winter may seem like a good idea to offset their energy deficit, but it often causes more problems and can become very costly. See WDFW’s Winter Wildlife Feeding information for details.

Anderson says a good way to watch wildlife in winter that is less apt to cause disturbance is to use specific sites that separate viewers from wildlife by motor vehicle routes, trails, boardwalks and blinds. These include:

  • Whatcom Wildlife Area’s Lake Terrell Unit, ten miles northwest of Bellingham and five miles west of Ferndale in Whatcom County; wildlife viewing is available year-round on a fishing pier from where you can see trumpeter and tundra swans and bald eagles in winter; black-tailed deer are also viewable year-round.
  • Skagit Wildlife Area’s Johnson/Debay Swan Reserve, northeast of Mount Vernon in Skagit County; provides a winter feeding and resting reserve for trumpeter and tundra swans, and other wildlife, with grass and corn planted for swans and ducks; the large numbers of wintering waterfowl also attract bald eagles and other raptors; beaver and river otters inhabit the sloughs year-round; public parking and access is provided as well as two parking/viewing areas for disabled users
  • Skagit Land Trust’s Hurn Field, west of Sedro-Woolley in Skagit County; offers wintering area for elk, but also viewable waterfowl and winter birds; viewing area constructed by WDFW.
  • Skagit Wildlife Area’s Fir Island Farms Snow Goose Reserve, on Fir Island Road, and adjacent to the Skagit Bay estuary in Skagit County; provides a winter-feeding and resting area for thousands of snow geese with fields of winter wheat grown for the birds; walk along the dike to scan for waterfowl and shorebirds, including wintering dunlin and numerous bald eagles.
  • Central Puget Sound urban areas: Kent Ponds for waterfowl and raptors, Discovery Park for wintering passerines and bluff overlooks to see wintering seabirds on the sound, Edmonds waterfront/Carkeek Park/Quartermaster Harbor from Vashon or Maury Island/Seahurst Park/Des Moines Beach Park for beach/shoreline wintering seabird watching; Union Bay Natural Area (Center for Urban Horticulture) for winter waterfowl and passerines.
  • Nisqually National Wildlife Refuge, northeast of Olympia in Pierce County; thousands of ducks and geese through the winter, plus raptors and songbirds year-round; black-tailed deer, mink and coyotes are at the forest edge; one-mile trail provides access to many habitats and numerous observation decks and somenew elevated walkways will be open in January.
  • Olympic Peninsula areas: Ocean Shores North Jetty and Damon Point shoreline trails in Grays Harbor County, and Willapa Bay, Long Beach Peninsula, and Leadbetter Point shoreline lines in Pacific County to view wintering seabirds
  • Ridgefield National Wildlife Refuge, in Columbia River floodplain north of Vancouver in Clark County; hosts thousands of wintering waterfowl including tundra swans, Canada geese, cackling geese and many duck species; year-round see raptors, coyotes, river otter and herons; a 4.2-mile auto tour route is open daylight hours through winter; wintering tundra swans also viewable at Franz Lake on Washington side of the Columbia River Gorge and Mirror Pond at the foot of Crown Point in Oregon.
  • Oak Creek Wildlife Area, northwest of Yakima in Yakima County; winter elk feeding program (to keep animals off of adjacent private lands where they cause damage) has side benefit of easy and close viewing from high-fenced visitor parking lot off Hwy. 12; bighorn sheep also fed in some units; check recorded message at (509) 653-2390 for updates on feeding start-up and volunteer-led, elk-viewing tours (by reservation only through (509) 698-5106).
  • Toppenish National Wildlife Refuge, south of Toppenish in Yakima County; wintering waterfowl and raptors; wildlife observation and hiking are allowed year-round in the southeast portion of the main refuge from Highway 97 to refuge headquarters.
  • Pineside Sno-Park Loop on Gifford Pinchot National Forest in Klickitat County; dying trees from budworm outbreak in the 1990s are loaded with insects and attract Williamson’s sapsucker; hairy, white-headed, three-toed, black-backed, and pileated woodpeckers; brown creepers, and other birds; birdwatch while cross-country skiing and snowshoeing the area.
  • Conboy Lake National Wildlife Refuge in northwest Klickitat County; wintering rough-legged hawks, northern shrikes, common redpolls; other winter viewable species include tundra and trumpeter swans; greater white-fronted goose; cinnamon teal; northern pintail; northern harrier.
  • McNary National Wildlife Refuge, near the confluence of the Snake and Columbia rivers southeast of Tri-Cities in Walla Walla County; some 100,000 Canada geese and mallards winter here, plus tundra swans and a variety of duck species; one-mile loop Burbank Slough Wildlife Trail and viewing blind available.
  • Echo Ridge Nordic Ski Area in Okanogan-Wenatchee National Forest, north of Chelan in Chelan County; snow buntings and other wintering birds; watch for cougar and bobcat tracks from 25-mile cross-country skiing trail loop around ridge tops with vistas of Lake Chelan and surrounding mountains.Sinlahekin Wildlife Area’s Sinlahekin Unit south of Loomis in Okanogan County; year-round hawks, eagles, white-tailed deer and diversity of other wildlife species; watch wildlife from viewing blinds or via 11-mile nature trail traversible in winter when snow conditions exist on cross-county skis or snowshoes.

More details on some of these and other sites for winter wildlife viewing are available in the Audubon Great Washington State Birding Trail series of maps (http://wa.audubon.org/birds_GreatWABirdingTrail.html) and at http://wdfw.wa.gov/viewing/.

Water is key to complete backyard wildlife habitat

Water is often a limiting factor in a backyard wildlife habitat.

While most species need to consume water regularly, either directly or through their food, some also require it for cleanliness and fitness. Many birds need water for bathing and post-bath preening to keep their feathers in shape to provide “all weather” protection.

The provision of water, including through fall and winter freezes, can turn an average wildlife habitat into an extraordinary one.

Those fortunate enough to have a natural waterway running through their property already have that “extraordinary” status. But most of us need to create sources of water, either building ponds, ditches, landscape swales, or rain gardens, or setting up birdbaths.

The trick with maintaining a birdbath through the winter months in many parts of Washington, of course, is keeping the water thawed.

Birds need to drink and bathe even on the coldest days, and although they can use snow and melting ice, open water may be more attractive. Keeping water just above freezing between dawn and dusk, when birds are active, is key.

You can keep a birdbath free of ice by regularly pouring water into the bowl, but that quickly becomes tedious during extreme cold when water freezes rapidly. A stick of wood left in the water during cold snaps can help you pop out the ice so you can add fresh water. When the water freezes, the stick will also help prevent the birdbath from cracking. Providing water next to a reflecting window can also help keep it open.

Birdbaths equipped with submersible, thermostatically controlled heaters will save time and maybe the birdbath itself. Small heaters designed to operate at a depth of one to three inches, many with automatic shut-off features when water levels drop or evaporate, are available through garden and hardware stores that cater to bird-feeding enthusiasts, and catalogues or on-line businesses.

Be careful about the source of electricity needed to run a birdbath heater. Outdoor outlets should be on a circuit or outlet protected by a ground fault circuit interrupter (GFCI), which will cut off the flow of electricity in the event of a short. Most outlets in newer homes are GFCI-protected, but if you’re not sure about yours, have outlets checked by an electrician.

Providing water for birds and other wildlife comes with the responsibility to keep the water clean to prevent diseases from spreading. This is especially important during warm months, but periodic thaws during cool months can be deadly, too. Scrub the birdbath a few times each month or briskly hose it out to remove algae and bacteria. Change the water frequently; locating the birdbath near a hose bib is a good idea. Never add chemicals to clean or keep water from freezing because you may poison wildlife.

If providing open water consistently through winter is difficult for you, consider other ways you can help your backyard birds and other wildlife.

Drinking water is obtained by some animals through fleshy fruits, berries and other plants they eat in your landscape. Some birds bathe in dust, rather than water, sifting and shaking soft, dry soil through their feathers to clean them for thermal regulation. Wrens, sparrows, quail, grouse, pheasants and hawks will enjoy vigorous dust baths in a tilled garden space or specially-dug area with a mixture of loose sand, loamy soil, and wood ashes.

Naturalize your backyard bird feeding

As sure as leaves turn color and fall to the ground at this time of year, bird feeders are filled and placed in backyards across Washington.

Window-side, arm-chair birdwatchers enjoy drawing both migrant and resident birds into close-up view in this traditional way.

It’s a tradition to continue only if you keep those bird feeding stations immaculately clean; use high quality feed and feeder types that only birds can access; locate them to avoid problems with window collisions, predatory cats, and other wildlife like deer and bears; and recognize that feeding only provides temporary benefits to some birds.

The Washington Department of Fish and Wildlife (WDFW) recommends simplifying and “naturalizing”  the tradition of backyard bird feeding by landscaping with plants that provide berries, fruits, seeds, or nuts for your feathered friends.

Many of these natural bird feeding plants will add beautiful color to your fall homescape. And there’s no time like fall, when plant root systems slow down and go dormant, to add trees, shrubs and even some perennials.

Some of the best plants that provide soft fall and early winter fruit include Pacific crabapple, red-osier dogwood, elderberry, gooseberry, huckleberry, Western serviceberry, and madrone.

Plants that best provide fruit that will last through winter and into early spring, when food is in short supply, include barberry, currant, firethorn, Douglas hawthorn, Rocky Mountain and Western junipers, Sitka and Cascade mountain-ash, Oregon-grape, snowberry, sumac, and wild rose.

Three great seed and nut-producing trees for western Washington landscapes are hazelnut, vine maple, and birch. For larger areas, include oaks and conifers.

Wildlife-friendly seed and nut trees for other parts of the state include alder, Douglas fir, and other conifers.

More birds than not use seeds, and lots of shrubs and perennial flowering plants provide them. But the key to this naturalized bird feeding is to leave those “dead heads,” or spent flowers with all those seeds. Leave that kind of clean up for spring, and enjoy watching your bird visitors do some of the work this fall!

Among the best seed-producing shrubs are mock-orange, ninebark and oceanspray.  There are dozens of garden perennials that are good seed-providers, including aster, black-eyed susan, blanketflower, calendula, goldenrod, columbine, coneflower, coreopsis, cosmos, fall sedum, lupine, nasturtium, sunflower, sweet pea, and yarrow.

Check with your local nurseries for other appropriate plants that will not be weedy or invasive in your part of the state.

For more information about naturalizing your backyard bird feeding, see WDFW’s Backyard Wildlife Sanctuary program at http://wdfw.wa.gov/living/backyard/index.html. A good source of detailed information about plant species is available in the “Landscaping for Wildlife in the Pacific Northwest” book by WDFW wildlife biologist Russell Link, available through WDFW’s North Puget Sound regional office in Mill Creek (see http://wdfw.wa.gov/living/book/index.html.)

Bird watching
Keep that dead or dying tree right where it is (unless, of course, it’s truly a hazard to you), so we can feast on the insects in the rotting wood or make winter roosts or dens in its cavities

Fall “To Do” list from your backyard wildlife family

Your family may be making those fall outdoor chore lists, as daylight hours shrink, temperatures drop, and the urge grows to “batten down the hatches” in the yard and garden.

Here’s another “to do” list from your local wildlife “family” that you may find easier to check off:

  • Leave some “dead heads” on your flowering plants to provide seeds for some of us birds and other animals
  • If you must rake leaves off grass lawns, just pile them under some shrubs, bushes or other nooks and crannies to provide homes for those insects that we birds love to eat; leaves make great mulch to help your plants, anyway!
  • Keep that dead or dying tree right where it is (unless, of course, it’s truly a hazard to you), so we can feast on the insects in the rotting wood or make winter roosts or dens in its cavities
  • Give yourself and your mower a rest for at least a portion of your lawn so we’ve got a patch of taller grass to hide and forage in
  • Save just a little of that dead bramble thicket for us – it makes great winter cover and we don’t need much!  Fall is a good time to plant shrubs, so replace invasive, exotic Himalayan and cutleaf blackberries with native plants of higher wildlife value like blackcap (native black raspberry) or red raspberry; native currants or gooseberries found in your area; or native roses such as Nootka or baldhip. 
  • Pile up any brush or rocks you clear around your place to give us another option for nests and dens
  • Take it easy on yourself and let go of the “perfect” garden image; we wild animals like less tidy, “fuzzy” places because there’s usually more food and shelter there
  • Get yourself a comfortable chair, sit back, and congratulate yourself on having made a home for wildlife and a haven of relaxation for yourself!

Bird watching
Well-fed cats, either feral or domestic, become “super-predators” of birds and other wildlife.

Don’t help cats hurt wildlife

Wild birds and free-ranging cats are not a good mix.

As a backyard wildlife enthusiast, you control your own cat and talk to cat-owning neighbors about doing the same.

But feral cats – those untamed strays that now total up to an estimated 10 million throughout the United States – can, and have, seriously damaged wild bird and other wildlife populations.

While domestic cats are solitary animals, colonies of feral cats often form around food sources like bird feeding stations, garbage dumps, or places where people deliberately leave food for them. In fact, many colonies of feral cats are supported by well-meaning but misinformed advocates of what’s become known as “TNR” management: Trap, Neuter, Release.

The theory behind TNR programs is eventual reduction of feral cat colonies. But sadly, such claims are not substantiated and research shows continuing negative impacts to wildlife (as most recently documented by Darcee Guttilla and Paul Statt from California State University  in the Journal of Mammalogy http://www.bioone.org/doi/abs/10.1644/09-MAMM-A-111.1 .)

Cat colonies often serve as dumping grounds for other unwanted cats. The food provided usually attracts more cats. Contrary to TNR proponent beliefs, colony cats do not keep other cats from joining the colony. As time goes on, some colony cats become too wary to be caught, so rarely are all spayed or neutered. With females capable of producing up to three litters of four to six kittens each every year, it doesn’t take long to grow a feral cat colony.

Well-fed cats, either feral or domestic, become “super-predators” of birds and other wildlife. The need to eat and the instinct to hunt can and do function separately. Any cat owner can attest to this fact with stories of “gift birds” laid at their feet by feline companions.

Almost one-fifth of all injured wildlife brought to Washington’s wildlife rehabilitators across the state was harmed by cats.

In addition to their threats to wildlife, feral cat colonies pose human health risks. Even TNR-managed colonies can spread disease such as ringworm, toxoplasmosis, cat scratch fever, and rabies, since every cat is not captured regularly for health care.

Free-roaming cats usually have short, miserable lives, due to collisions with motor vehicles, attacks by other domestic and wild animals, accidental poisoning or trapping, and parasites and diseases. The Humane Society of the United States reports that the expected life span of an indoor cat is at least triple that of cats that spend their lives outdoors.

TNR management of feral cats is clearly not in the best interests of anyone, and it often overwhelms the ability of well-meaning people who genuinely want to help animals. It also undermines efforts of responsible pet owners who keep their cats indoors.

Keep summertime easy for you and your backyard wildlife

If you want to keep your livin’ easy this summer in your Backyard Wildlife Sanctuary, try xeriscaping.

Xeriscaping (pronounced “zeer-i-scape-ing”), from the Greek word “xeros” for dry, is landscaping with drought-tolerant plants that, once established, require less water and less overall care.

Some call it sustainable landscaping or “stewardship gardening,” as in being stewards of natural resources, including water. Less water used on your lawn and garden ultimately means more water for other uses, including fish and wildlife needs.

By definition, native plants manage to thrive on local precipitation and are used by local wildlife for food and cover. So they’re a natural for a sustainable, wildlife-attracting landscape. Many other low-water use plants that are adaptable to local soil conditions and climate are also well-used by wildlife. Be sure to research the soil and site needs when planting natives as some prefer sun while others prefer shade.

Standard bluegrass lawns are water hogs, at least if you insist on keeping them bright green throughout the summer. Consider cutting back on the watering, even letting some of it go dormant as grasses are meant to do naturally.

Or consider converting some lawn space without foot traffic to bunch grasses or ground cover. Use native, drought-tolerant bunchgrasses like Idaho fescue, bluebunch wheatgrass or Great Basin wild rye, but keep in mind they grow in bunches, not sod-forming networks of roots or rhizomes like bluegrass, so they’re not for walking on.  Use low-maintenance ground covers, like bunchberry, kinnikinnik, low Oregon grape or native strawberry.

Perennial flower beds can be just as colorful throughout the growing season as thirstier annuals with arrangements of native or drought-tolerant species like Bee balm, Columbine, Coral bells, Daylilies, Lavender, Purple coneflower, Penstemon, or Yarrow.

Small to large shrubs, both deciduous and evergreen, that add an important layer in the landscape for wildlife and are relatively low-maintenance once established, include Basin big sage, Chokecherry, Currant, Elderberry, Ninebark, Oceanspray, Red osier dogwood, Serviceberry, Snowberry, Sumac, and Wild rose.

Trees that tend to do well without a lot of attention include Douglas fir, native Mountain ash, Rocky Mountain juniper, Rocky Mountain maple, vine maple and Pine.

Although it may be too warm and dry now to plant new stock, it’s a great time to visit arboretums and nurseries to look at these and other plants and to find a supplier so you’re ready to plant this fall.

An increasing number of nurseries across the state are including native and drought-tolerant plant species in their sales stock, and the more gardeners ask for them, the more they’ll provide. Some nurseries specialize in these plants and can be found through the Washington Native Plant Society (http://www.wnps.org/index.html).

Watch carefully

The summer outdoor recreation season includes lots of wildlife watching, whether it’s in your own backyard or afield in woodlands or on waterways.

Washington Department of Fish and Wildlife (WDFW) biologists remind you to watch carefully so that wild animals are not disturbed during this reproductive season.

“It’s great to see our breeding birds and other wildlife back in Washington now,” said WDFW wildlife biologist Christopher Anderson, “but we all need to be careful about stressing them to the point where they decide to set up housekeeping somewhere else.”

Anderson says some “well-intentioned attention” can alter the success of breeders and nesters, either directly or by inadvertently drawing predators. For example, trampled vegetation that reduces cover and creates paths to a nest site affords opportunities for domestic cats or coyotes to hone in on baby birds. Highly intelligent corvids, like crows and ravens, are even known to observe human activity to find vulnerable prey.

Wildlife parents that have to be more vigilant to protect their young -- spending time and energy to ward off curious people and hungry predators – may not be as successful in providing food for those young.

WDFW biologists advocate these "low-impact" wildlife watching tips:

  • Respect wildlife’s need for space and privacy by using binoculars, scopes and telephoto camera lenses instead of trying to get too close
  • Fade into the surroundings by being quiet, wearing natural colors, trying not to throw a shadow, and hiding at a distance
  • Spend time sitting still, moving slowly, and using more than your sense of sight to experience wildlife – listen and smell, too

“Let wild animals be themselves,” Anderson adds. “Don’t try to feed them or pick up what you think is an animal in need.”

Most wild babies brought to WDFW offices, or directly to one of the 50 some WDFW-licensed volunteer wildlife rehabilitators, are NOT helpless or abandoned.

Can you -- should you -- save” that wild baby?

It’s hard to resist “rescuing” a baby bird, deer fawn, or other young wildlife that ends up on your lawn or driveway at this time of year.

When a wild baby seems helpless or abandoned, you want to help.

But most wild babies brought to Washington Department of Fish and Wildlife (WDFW) offices, or directly to one of the 50 some WDFW-licensed volunteer wildlife rehabilitators, are NOT helpless or abandoned.

In fact, most “rescuers” unwittingly stole the young animal from its parents, some who may have even witnessed the well-intentioned abduction.

Young wild animals are often left alone for hours while their parents gather food. Young birds commonly leave the nest before they are fully-feathered and are fed on the ground by their parents for a day or two until they are able to fly. Doe deer leave their fawns alone to avoid drawing predators with their own body scent.

More often than not, just leaving a young animal alone affords it the best chance for survival.

Leaving wildlife alone means you need to confine cats, dogs and other pets that can cause lethal injury. One of the most common causes of injuries to wildlife, that always need a wildlife rehabilitator’s care, is attacks by cats.

One of the few situations in which almost anyone can help wild babies is when very young, completely un-feathered birds have fallen out of the nest and are on the ground.

If you can find the nest and safely reach it, simply pick up the nestling with a gloved hand and put it back in the nest. Contrary to popular belief, the parent birds will not reject their young because it’s been handled by humans.

If you can’t find the nest, place the bird in a tree or shrub or on a shaded portion of a roof, out of the way of cats, dogs, and children. You can even make a “nest” for it with a small box filled with leaves or soft cloth; place the nestling in the box and put it in a tree or shrub or otherwise protected from rain or sun. Always place the bird or “nest” back in the area where the young was found. Don’t handle it a lot or attempt to feed it.

If you watch from a distance, you’ll likely witness the parent birds tending to their lost-and-found young.

Wild animals of any age that show obvious signs of illness or injury such as bleeding, vomiting, panting, shivering, or ruffled feathers or fur, or that are just lethargic and make no effort to escape your approach, may indeed be in need of care.

Most Washington counties have wildlife rehabilitators, listed with phone numbers and addresses for 24-7 access on the WDFW website at http://wdfw.wa.gov/conservation/health/rehabilitation/index.html.

If you and your local rehabilitator decide it might be best to help the animal, find out from them how to safely contain and transport the animal. Always wear gloves when picking up a wild animal to place it in the container. Until the animal is transported to the rehabilitator, keep it in a quiet, dark place.

Another way to help wildlife, whether or not you find an injured animal in need of care, is to support your local volunteer wildlife rehabilitators. All of these volunteers must establish and maintain a good working relationship with a cooperating veterinarian, and many are veterinarians themselves; none can charge for their services to wildlife, but may accept donations.

Go native with Spring planting

Backyard Wildlife Sanctuary managers are as vulnerable as any gardeners to the lure of colorful new plants displayed in nurseries and home improvement stores now.

But if you’re adding plants to your landscape this Spring, consider doing more for the wildlife you want to attract by going native. 

Native plants naturally provide just the right food and cover for birds, bees and other critters. They’re also easier on you and kind to the earth in general because their maintenance requirements are suited to our climate. That means less watering, less fertilizing, less pest control, less winter mulching -- less care and resources overall to sustain them year after year.

Anyone thinking that native plants can’t possibly be as attractive as those exotics now on display hasn’t taken a look at natives in our neck of the woods.

It’s hard to beat the beauty of columbine, bleeding heart, coral bells, penstemon and honeysuckle – all natives, all beloved by hummingbirds for their nectar.

Showy but native rhododendrons, lupines and phlox support butterflies. 

And asters, blanketflower, daisy fleabane and wild sweet peas produce seeds used by a variety of songbirds.

There’s no better time to go native than this month as we celebrate not only Earth Day on April 22, but also Native Plant Appreciation Week, April 25 – May 1.

You can learn more about native plants in our area and resources for acquiring them from the Washington Native Plant Society at www.wnps.org.

The group’s northeast chapter is hosting a Native Plant Landscape “Open Garden” on Saturday, May 1, 12-noon - 4 p.m., at the Washington Department of Fish and Wildlife (WDFW) Eastern Region Office (2315 N. Discovery Place, Spokane Valley) where chapter members have been re-working the grounds with native plant landscaping.  For more information on the event, call (509) 466-8886.

Be careful with Spring bird feeding

If you like to maintain backyard bird feeding stations through the spring or year-round, be careful to avoid spreading diseases among wild birds.

Influxes of spring migrants, warmer temperatures, and wetter conditions mean that you need to be diligent about keeping feeders clean and dry.

There are several diseases that birds can pick up at or around feeding stations.

Salmonellosis is probably the most common avian disease, afflicting species such as finches, grosbeaks and pine siskins that flock together in large numbers at feeders and transmit the bacteria through droppings. The first indication is often a seemingly tame bird on or near a feeder. The birds become very lethargic, fluff out their feathers, and are easy to approach, but there is very little that can be done to treat them.

Aspergillosis is caused by a fungal mold that grows on damp feed or soil in or around the feeder. Birds inhale the fungal spores and the disease spreads through their lungs and air sacs, causing bronchitis and pneumonia.

Avian Pox is a viral disease that causes wartlike growths on birds' faces, legs, wings and feet. The virus is spread by direct contact with infected birds, ingestion of food and water contaminated by sick birds, or contact with contaminated surfaces such as at feeders, birdbaths, and perches. Insects, especially mosquitoes, also carry the disease from one bird to another.

Trichomaniasis is caused by small parasites that can affect a wide variety of animals. The mourning dove and band-tailed pigeon seem to be particularly susceptible. The disease causes sores in their mouths and throats, and results in death from starvation or dehydration.

If evidence of any disease is seen, immediately remove feeders and/or clean them with a bactericide, like a ten percent chlorine or bleach solution (one part bleach to ten parts warm water). Soak feeders and all parts for at least 10 minutes. Scrub, thoroughly rinse, and dry completely before re-using.

Whether you see disease or not, it's good prevention to clean feeders this way every time you re-fill them. Avoid using wood feeders because they're difficult to keep clean. Make sure feeders allow rainwater to drain easily.

One of the best ways to avoid disease problems during the wet months is to remove or minimize use of feeders and maximize use of food-producing plants in your yard.

Other ways to minimize chances of a disease outbreak at feeders include:

  • Use only tube feeders - Platform feeders that have more flat surfaces collect more droppings, fungus, and other dirt that may spread disease.
  • Give birds space - Spread feeders over a greater space. Crowding is a key factor in spreading disease because birds have more direct contact, jostle each other, and are stressed and thus more vulnerable. Use smaller feeders that allow only a couple of birds to feed at a time.
  • Clean up wastes - Regularly rake the area underneath feeders to remove droppings and old, moldy seed. Mount feeders over a surface that can be swept easily. Move feeders around periodically to keep droppings from collecting.
  • Use good feed - If any feed smells or looks musty or moldy, don't use it. Disinfect storage containers and scoops used with spoiled feed before replacing with fresh, clean, dry feed.
  • Avoid seed mixes - Most birds will scatter mixes, especially those with mostly milo or millet, for more preferred seed and the waste on the ground can become wet and moldy.

It's possible, although uncommon, for people to become sick from the salmonella bacteria through direct contact with infected birds, bird droppings, or through pet cats that catch sick birds.

When you handle bird feeders, bird baths, or sick or dead birds, wear gloves and wash your hands thoroughly afterwards.

Don’t Feed Coyotes

Coyotes, which live throughout the state in both rural and urban areas, breed in late winter and by early spring are feeding pups. You may see coyotes almost anywhere in Washington, including in suburban and even urban areas.

Enjoy watching them, but don’t feed coyotes, either intentionally or by allowing them access to food such as garbage and pet food.

Earlier this year, WDFW officials had to euthanize a coyote that had become aggressive toward people in Seattle’s Discovery Park and the nearby Magnolia neighborhood. The animal’s bold behavior indicated it had learned to associate humans with food.

Normally, coyotes avoid people but they may become habituated to humans—and abnormally bold—if they are intentionally fed or find food near human residences. While most people don’t directly feed coyotes, many unwittingly leave food that draws these opportunistic omnivores.

Unsecured garbage or compost piles can be a food source for coyotes or for smaller animals that are prey for coyotes. Secure garbage and compost bins with tight fitting covers. Don’t let spilled seed pile up under bird feeders. Don’t leave pet food outside.

Protect cats and small dogs by keeping them indoors, especially from dusk to dawn. Coyote conflicts with off-leash dogs can increase in early spring when coyotes are more territorial, and may have their pups in tow.

Although coyote sightings and attacks on pets occur periodically throughout the state, attacks on humans are extremely rare. Only two such attacks have been documented in Washington–in 2006 a coyote bit two young children in Bellevue and was later euthanized.
