The short-tailed albatross is a rare visitor to Washington waters. It breeds on islands off Japan and in Hawaii. Its population is currently around 7300 individuals and growing. The main population is vulnerable due to about 85 percent of nesting pairs concentrated on a single island. Fishing vessels and fishing tactics are also threats.

Description and Range

Physical description

The short-tailed albatross is the largest pelagic seabird in the North Pacific Ocean, with a wingspan of 7 to 7.5 feet. These birds have a noticeably large pink bill. Adults have a pale-yellowish head, and are mostly white. Juveniles in their first year have dark brown plumage; subadults have dark plumage on top of their head, neck and back but their underside is white with brown mottling.  

Ecology and life history

The short-tailed albatross first breeds at 5 to 9 years of age. Pairs mate for life, and lifespan is about 45 years.

They are ocean surface feeders, relying primarily on squid, flying fish, fish eggs, and crustaceans. They also follow fishing vessels for bait lines and processing scraps.

Geographic range

During breeding, adults forage primarily in the upwelling zones off northern Japan. During northern summers, mostly adult birds follow trade winds to the edges of the continental shelves from China north to the Aleutian Islands and Bering Strait. Immature birds (less than three years) largely occur at the eastern Pacific continental shelf from the Alaskan gulf south to southern California.

The 2018-2019 estimate is 1,011 breeding pairs amongst all locales, while the total population is estimate to be 7,365.

Recolonization efforts began in the late 1970s, and the population is now growing at an average rate of 8.9 percent per year. However, short-tailed albatross are still vulnerable because the main breeding colony, which supports about 84 percent of nesting pairs, is located on an unstable volcanic island.

This species was known to have occurred offshore of Washington and British Columbia, where they were considered common in the mid-19th to early 20th century.

Climate vulnerability

Sensitivity to climate change

Low-
Moderate

Although short-tailed albatross are unlikely to have physiological sensitivity to climate change and their breeding habitat is also unlikely to be affected by climate change, their sensitivity will be increased by potential shifts in prey availability. Given that albatross primarily forage in areas with strong upwelling and high oceanic productivity along the continental shelf, potential shifts in ocean circulation could limit the availability of prey (e.g., squid, crustaceans, flying fish). Additionally, potential northward shifts of primary prey species like squid could result in a northward shift in albatross populations.

Conservation

This species is identified as a Species of Greatest Conservation Need (SGCN) under the State Wildlife Action Plan (SWAP). SGCN-classified species include both those with and without legal protection status under the Federal or State Endangered Species programs, as well as game species with low populations. The WDFW SWAP is part of a nationwide effort by all 50 states and five U.S. territories to develop conservation action plans for fish, wildlife and their natural habitats—identifying opportunities for species' recovery before they are imperiled and more limited.
This species is identified as a Priority Species under WDFW's Priority Habitat and Species Program. Priority species require protective measures for their survival due to their population status, sensitivity to habitat alteration, and/or recreational, commercial, or tribal importance. The PHS program is the agency's main means of sharing fish and wildlife information with local governments, landowners, and others who use it to protect priority habitats for land use planning.

Once thought to be the most abundant albatross species in the North Pacific, this species was hunted to near-extinction by 1949. Exact populations were not known, but between 1885 and 1903 it is estimated that more than five million birds were harvested from one island colony alone (Torishima, Japan). The short-tailed albatross is designated as a “National Monument” in Japan, and regulations now prohibit harvest of this species.  

Conservation Threats and Actions Needed

  • Habitat loss or degradation
    • Threat: Natural volcanic disturbance on main breeding island could decimate recovering populations. Eroding soils at site cause nest failure.
    • Action Needed: Use land acquisitions, conservation easements and landowner agreements to protect significant colonies; reintroduce on former breeding sites; translocation of chicks.
    • Threat: Chronic pelagic pollution: plastic debris, chemical and petroleum contaminants and toxic metals.
    • Action Needed: Monitor and conduct research of short/long-term effects on chicks and adults.
  • Overharvesting of biological resources
    • Threat: Bycatch from commercial longline fisheries; wire/cable strikes from trawlers.
    • Action Needed: Enforce North Pacific protective fishing equipment regulations. Increase on-board vessel observer efforts.
