Two species
of rabbits are native to Washington and two others have been introduced
to the area (Table 1). Washington is also home to three species
of hares: the snowshoe hare and two others, called “jackrabbits.”
Rabbits differ
from hares in that female rabbits give birth to blind, hairless
young that require considerable attention for their first two weeks
of life. Hares are born fully furred with their eyes open, and can
hop about within hours of their birth.
This handout
is primarily about rabbits; however, information on how to prevent
problems with jackrabbits is provided under “Preventing
Conflicts.”
Facts
about Rabbits
Food and
Feeding Habits
- From spring
to fall, rabbits and hares eat grass, clover, wild flowers,
weeds, and farm and garden crops. In winter, their diet shifts
to buds, twigs, bark, conifer needles, and practically any green
plant.
- In dry
interior areas, Nuttall's cottontails climb sloping tree trunks
to access green, dew-laden vegetation.
- Rabbits
and hares re-ingest their droppings to further digest the material,
a process called coprophagy. After returning to their shelters,
they pass soft pellets containing undigested vegetation, and
then eat these at a more leisurely pace, later passing hard
pellets.

rabbits live in groups in large, complex burrow systems called
“warrens.”

Nest
Sites and Shelter
- Females
of most rabbit species create a shallow, bowl like nest called
a “form,” and line it with leaves, grass, and fur
plucked from their bellies.
- Female
domestic rabbits (and our rare Pygmy rabbits) excavate burrows
for their shelter and den site.
- Where soil
conditions and food supplies permit, domestic rabbits live in
groups in large, complex burrow systems called “warrens”
(Fig. 2).
- Nests
and dens are located in or near brushy fencerows or field edges,
brush piles, gullies containing shrubs, and landscaped areas
with suitable cover.
Reproduction
- The breeding
season for rabbits begins in mid February and can continue through
late summer. Famous for their reproductive abilities, rabbits
have a 30-day gestation (pregnancy) period, and have several
litters containing four to eight young each year.
- For about
two weeks, the mother rabbit stays away from the nest so as
not to show predators the location of the young, returning only
at dusk and dawn to nurse and lick her young clean.
- At two
weeks of age the young rabbits begin to eat vegetation; at four
to five weeks old they are feeding alongside their mother.
- The number
of rabbits in a given area will increase and decrease in a cycle
connected with predator populations and food availability.
Mortality
and Longevity
- Adult
rabbits are preyed on by large hawks and owls, domestic dogs,
coyotes, foxes, and bobcats. Vehicles also kill many rabbits.
- The young
are eaten by mink, skunks, long-tailed weasels, gopher snakes,
and domestic cats; young in nests are vulnerable to weed-wackers,
lawn mowers, hay mowers, and other agricultural equipment.
- Rabbits
may live two or more years in the wild, but when predators are
numerous and weather conditions are extreme, they seldom live
more than a year.

areas, weed and tall-grass patches, and orchards throughout
eastern Washington. (From
Christensen and Larrison, Mammals of the Pacific Northwest:
A Pictorial Introduction.) |
Native
Rabbits
The
Nuttall's cottontail (Sylvilagus nuttallii, Fig.
3) averages 14 inches in length, is gray or brownish-gray, and
has a relatively short, inconspicuous white tail. It is found
in sagebrush areas, weed and tall-grass patches, and orchards
throughout eastern Washington.
The Pygmy
rabbit (Sylvilagus idahoensis) is the smallest rabbit
in North America, measuring only 11 inches in length. It is slate-gray
with a buff-colored tail and is found in the dense sagebrush and
rabbitbrush areas of south-central Washington (where fewer than
50 of these rabbits exist)
Introduced
Rabbits
The Eastern cottontail (Sylvilagus
floridanus) was introduced to several areas in Washington
as a game animal beginning in the 1930s. It averages 17 inches
in length and is light brown in color; the white underside of
its 2-inch tail is readily visible when the rabbit runs. It is
commonly seen along roads, brushy fencerows, and blackberry thickets
in and around areas where it has been introduced.
The domestic
rabbit (Oryctolagus cuniculus) is another introduced
species. Also known as the European rabbit or Belgian hare, this
single species is the ancestor of all domestic rabbits (about
80 varieties!). The domestic rabbit is considerably larger than
other Washington rabbits, measuring 20 to 30 inches in length.
It has black, white, brown, or multicolored fur, and is most frequently
seen in the San Juan Islands where it was first introduced in
1900, although it is spreading into other areas where it has been
released.
Viewing
Rabbits
Rabbits and
hares are most active at dawn and dusk. Because their eyes shine
yellow or red in a flashlight beam, they are easily seen at night.
Rabbits do not hibernate.
During the
day, rabbits rest under overhanging limbs, brambles, brush piles,
old farm implements, and junk. In extreme cold or heat, they may
seek greater protection by burrowing into snowdrifts or using
another mammal's unoccupied burrow.
Rabbits' survival
depends on their sitting still for long periods, a trait they've
likely developed to avoid being seen by predators who watch for
movement. Indeed, the most common way to find a rabbit's or hare's
resting site is by accidentally scaring the animal from it.
Rabbits establish
safe "bolt areas," then move out in a radius from those safety
points to forage, always keeping bolt areas nearby. Animals on
the move are highly stressed because they are insecure until they
know the safe places they can bolt to.
| Releasing
Unwanted Pet Rabbits |
Every
few years the population of domesticated rabbits explodes
in many city parks and "wild" areas around urban centers due
to released or abandoned pet rabbits breeding.
Pet bunnies
are purchased at Easter and other times and later released
when people lose interest in them, move, feel the animal is
too messy, or when it is no longer cute and cuddly. Unfortunately,
domestic rabbits are not prepared to "live off the land."
Because
the release often happens in or close to residential areas,
these rabbits quickly begin feeding in gardens and flowerbeds,
causing conflicts with property owners. Disoriented rabbits
crossing roads in search of their own territories cause traffic
distractions and accidents. Biologists are concerned that
domestic rabbits can introduce diseases into wild rabbit populations
or mate with wild rabbits, undermining the vigor of wild populations.
Domestic
animals should never be abandoned to fend for themselves.
If you have a pet rabbit and no longer want it, take it to
an animal adoption center or find a home for it by advertising
or putting up signs in local pet shops and animal clinics. |
Trails
Rabbits commonly feed and travel along human paths,
rural roads, and roadsides.
Heavily used
rabbit trails look like 4-to 5-inch wide paths in grass, dirt,
decaying vegetation, and snow. In tall grass, trails are more
tunnellike. Tall blackberry thickets are a favorite shelter, and
nicely pruned little tunnels can be seen leading into these thickets

Figure
5. Signs of rabbits and hares include the clean-cut, angled
clipping-off of flower heads, buds, and young stems, and gnawing
on the stems of woody plants, blackberry canes and other brambles,
and on fallen twigs and branches.
(Drawing
by Jenifer Rees.) |
Tracks
Rabbit tracks show four toes on each print, with
the hind tracks being about two and a half times as long as the
front. The claws occasionally register, and on hard ground this
may be the only sign of a passing rabbit or hare.
Droppings
Rabbit droppings are easy to identify in any season
and are found in groups of five to ten scattered on the ground
in feeding areas (Fig. 4). Droppings are generally spherical,
sometimes slightly oblong or irregular, but never acorn- or capsule-shaped
like those of deer and elk. Rabbit droppings are about 3/8 inch
in diameter, and are composed of light brown, sawdust-like material.
Feeding
Areas
Look for the clean-cut, angled clipping-off of
flower heads, buds, and young stems up to ¼ inch in diameter
(Fig. 5). Evidence of gnawing can be found on the stems of woody
plants, blackberry canes and other brambles, and on fallen twigs
and branches.
A rabbit's
feeding area can also be located by looking for grass, clover,
plantain, and other weeds kept cropped to within an inch or two
of the ground.
In areas covered
with snow, young plants may be clipped off at snow height, and
the smooth, thin bark of trees and shrubs may be completely girdled.
Twig clipping
by rabbits and hares is sometimes confused with deer browsing.
Deer damage can be identified easily: It occurs above 2 feet and,
because deer have no upper front teeth and must twist and pull
when browsing, they leave a ragged break. Rabbits clip twigs off
cleanly, as if with a knife.

in many different ways. In areas with an abundance of trees,"half-cuts"
can create instant cover. (From:
Link, Landscaping for Wildlife in the Pacific Northwest.

Dust Baths
Rabbits and hares roll in dust baths to help rid
themselves of external parasites. These are small areas of sand
or dry soil, about a foot (30 cm) in diameter, that have been
cleared of vegetation, possibly through the animals' scratching
or through repeated use.
Calls
The large feet of the snowshoe hare make a good
sound thump, and often when a family group is together, one will
be lookout and thump a warning when something suspicious approaches.
A rabbit or hare captured by a predator emits a loud, high-pitched
scream.
Preventing
Conflicts
A rabbit's
appetite can get it into trouble with gardeners, landscapers,
orchardists, and foresters throughout the year. The following
are suggestions for preventing conflicts. For best results, use
control methods at the first sign of damage. Once rabbits and
hares are used to feeding in an area, all control tactics become
less effective.

Figure 7. A fence provides the most longterm and effective
way to protect plantings from rabbit and hare damage.
(Drawing
by Jenifer Rees.)
|
Fences:
Fences provide the most long-term and effective
way to protect plantings from rabbit damage. For rabbits, a 2-foot
tall fence, constructed with 1-inch mesh chicken wire and supported
by sturdy stakes or posts every 4 to 6 feet will exclude the animals
from an enclosed area. Larger hares (jackrabbits) ordinarily will
not jump a 2-foot fence unless chased by dogs or otherwise frightened.
Increasing the above-ground height to 3 feet will prevent them
from jumping a fence. Where deep snow is common, fences will need
to be higher, or adjusted to exclude animals during winter.
Rabbits and
hares are more likely to go under a fence than over it. To prevent
this, place the bottom of the fence 6 inches underground, stake
the bottom of the fence flush to the ground, or line the bottom
of the fence with rock, bricks, fence posts, or similar items.
Anther option is to create a 1-foot wide wire apron on top of
the ground on the animal side of the fence. Be sure to secure
the apron firmly with stakes (Fig. 7).
Electric netting
(a type of electric fence) is also suitable for rabbit exclusionl.
It is designed for ease of installation and frequent repositioning.
Electric netting is intended for temporary use at any one site,
making it ideal for seasonal gardens. Daily inspections will be
necessary during the first three weeks after installation. If
maintenance is poor, rabbits can do considerable damage to electric
netting fences by chewing through the wires. This could result
in sections becoming inoperative, which may be difficult to detect.
Note: Before purchasing the product, ask the representative
about the effects of electric netting on frogs, toads, and baby
rabbits. (See "Preventing
Conflicts" in Deer
for information on electric fences.)
The lower
2 to 3 feet of an existing fence or gate can be covered with 1-inch
wire mesh to exclude rabbits. Attach the protective wire to the
fence at enough points to prevent sagging, and follow the above
recommendations to prevent rabbits and hares from pushing through
from underneath. Use tight-fitting gates and keep them closed
as much as possible (Fig. 7).
Inspect the
fence regularly to make sure animals have not dug or pushed their
way under it, or worked their way over it. Once a rabbit gets
into a fenced area, it may not be able to get out without being
directed to a gate or other opening.

Figure
8. A cylinder of chicken wire, hardware cloth, or drainage
pipe can protect young trees from rabbit damage. Tree prunings
can be left as a decoy food source during the winter, as rabbits
much prefer twigs and buds to tree bark.
(Drawing
by Jenifer Rees.) |
Other barriers:
In some cases, protecting individual plants may
be more practical than excluding from an entire area. Newly planted
vegetables can be protected using commercially sold cloches or
1-gallon plastic milk containers that have the bottom cut out.
Placed over the seedlings, they provide protection from animals
as well as late frosts.
One-inch
mesh chicken wire can be cut and formed into cylinders and placed
around plants needing protection (Fig. 8). Bury the bottom of
the cylinders 3 inches below the soil line and brace them away
from the plants so animals cannot press against the cylinder and
nibble through the mesh. Inspect these barriers regularly to keep
the area inside the barriers clean of leaves, weeds, and other
debris, which can hide damage caused by mice and voles.
Individual
plants can also be protected with a variety of commercially available
protectors, including nylon mesh and plastic tubes; aluminum foil
has been double-wrapped around small trees with effective results.
Scare devices
and repellents:
If fencing and other barriers are impractical or
undesirable, or if damage is so slight that fencing is not cost-effective,
scare devices can provide temporary control. Visual scare tactics
include mylar tape and mylar party balloons located above areas
of potential damage, and pinwheels and other devices located at
ground level. However, urban and suburban rabbits are often unafraid
of such devices and other rabbits quickly get used to them. Ultrasonic
units, which rely on sound waves to repel rabbits, have not been
proven effective. A dog can help keep rabbits away, especially
if it is outside and awake at night.
Plants may
also be protected with commercially available or homemade taste
repellents that render the treated plant inedible. Research has
shown that repellents with putrescent whole-egg solids can reduce
browsing by rabbits.
Apply repellents
before damage occurs and reapply frequently, especially after
a rain, heavy dew, sprinkler irrigation, or when new growth occurs.
In all cases, follow the label directions for the repellent you
are using. Many repellents cannot be used on plants or plant parts
to be eaten by humans. (For recipes and detailed information on
repellents, see "Preventing
Conflicts" in Deer.)
Other nonlethal
control methods:
Encouraging natural predators of rabbits and hares—or
at least not interfering with them—may aid in reducing plant
damage. It is common to provide perches for owls and hawks in
some commercial areas to control rabbits, hares, and small rodents
(see "Maintaining
Hawk Habitat" in Hawks).
Another form
of control is to remove brush piles, weed patches, rock piles,
and other debris where rabbits live and hide. Before doing this,
consider the potential impact on other desirable wildlife species.
Plant rabbit-resistant
plants:
Protecting vulnerable plants from rabbit damage
within a fence, and landscaping with rabbit resistant plants elsewhere
makes an effective combination. A walk or drive through the neighborhood
can give you an idea of what plants are less palatable to these
animals. Note: When preferred foods become scarce,
there are few species that rabbits will not eat.
Rabbits sometimes
will browse the plants listed and sometimes will avoid plants
not listed.

list of rabbit resistant (or close to it) plants (Table 2) is

Live Trapping Rabbits
Trapping and
moving wild rabbits several miles away has appeal as a method
of resolving conflicts because it is perceived as giving the "problem
animal" a second chance in a new home.
Unfortunately,
the reality of the situation is quite different. The animals typically
become disoriented, which results in them getting hit by a car
or eaten by a predator. If they remain in the new area, they may
cause similar problems there, or transmit diseases to other animals
in the area. If a place "in the wild" is perfect for rabbits,
they are probably already there. It isn't fair to the animals
already living there to release another competitor into their
home range to the detriment of both of them.
In many cases,
moving rabbits will not solve the original problem because others
will replace them and cause similar conflicts. Hence, it is often
more effective to use the above recommendations for making the
site less attractive to rabbits, than to constantly trap them.
Trapping also
may not be legal in some cities; check with local authorities.
Transporting animals without the proper permit is also unlawful
in most cases (see "Legal Status").
If you cannot
resolve a conflict by other means—such as removing the attractant,
installing a barrier, applying a scare tactic—a final alternative
is to trap the rabbit. Trapping is the last option because it
presents many problems for both the animals and the trapper.
Single- or double-door type wire live traps that are 9 inches
high, 9 inches wide, and 26 inches long are effective at catching
rabbits. To capture hares (jackrabbits) in open terrain, use a
double-door trap with weighted doors to prevent escape. It is
best to use a larger trap than used on rabbits.
For bait,
use fresh vegetables in summer; apples, carrots, or bread in winter.
Place the trap near cover where rabbits feed or rest, or where
they gain entry under a fence. Place some bait just outside the
trap and spray the inside with apple juice to increase effectiveness.
For detailed
additional information on trapping rabbits, see Trapping
Wildlife.
Lethal
Control
Lethal control
may become necessary when all efforts to dissuade problem rabbits
fail. Shooting has traditionally been the primary form of controlling
rabbits and is effective in eliminating small, isolated groups
of animals. For safety considerations, shooting is generally limited
to rural situations and is considered too hazardous in more populated
areas, even if legal.
Public Health Concerns
Rabbits, hares,
voles, muskrats, nutrias, and beavers are some of the species
that can be infected with the bacterial disease tularemia (see
"Public Health Concerns"
in Beavers). Tularemia
can be acquired through ingesting undercooked rabbit meat or handling
a dead or sick animal. Anyone handling a rabbit or hare should
wear rubber gloves and wash his or her hands well when finished.
Legal
Status
Because legal
status, trapping restrictions, and other information about rabbits
change, contact your local wildlife
office for updates.
The Nuttall's
cottontail rabbit, Eastern cottontail rabbit, and snowshoe hare
are classified as game animals. A hunting license and open season
are required to hunt them.
A property
owner or the owner's immediate family, employee, or tenant may
kill or trap the above species on that property if they are damaging
crops or domestic animals (RCW
77.36.030). In such cases, no permit is necessary for the
use of live (cage) traps. However, a special trapping permit is
required from the Department of Fish and Wildlife for the use
of all other types of traps.
The domestic
rabbit is unclassified and may be trapped or killed year-round
and no permit is necessary; however, the above restrictions on
trapping devices still apply (RCW
77.15.192).
