Short-Tailed Albatross fledgling; USFWS
(Washington, D.C., June 24, 2011) A Short-tailed Albatross chick has successfully fledged on an island in the Hawaiian archipelago, marking the first time this endangered species has ever been known to breed successfully outside of Japan.
The hatchling broke through its shell in January on Eastern Island, one of three small, flat, coral islands that comprise Midway Atoll National Wildlife Refuge over 1,300 miles northwest of Honolulu. The parents of the Midway chick first paired up on the refuge four years ago. During that 2007-8 breeding season, they were observed spending only a little time together, but the following season, their time together increased. By the third season, they arrived at the Eastern Island breeding colony together and built a nest, but did not lay eggs. This breeding season, one of the pair was observed incubating a freshly laid egg on
After the egg hatched in January, the parents spent the next five months bringing squid and flying fish to their chick every one to three days. In doing so, they logged tens of thousands of miles, likely soaring between Midway and the nutrient-rich feeding grounds some 1,000 miles to the northwest. While the parents were both away on one foraging trip, the chick was swept off its nest by the tsunami resulting from the catastrophic Japanese earthquake of 11 March. It survived the ordeal, and in May, after months of steady feeding and growth, had lost most of its downy look and begun stretching and exercising its wings.
Anticipating its fledging, the chick was banded by FWS biologists on June 8. It has now left the island and is most likely headed in a northwesterly direction to the rich and productive waters near Hokkaido, Japan. On average, Short-tailed Albatrosses begin breeding at 6 years of age, but often begin prospecting at nesting sites several years earlier. So, it is our hope that this bird return in 4-6 years, and it could begin breeding by about 2017, provided it finds a mate.
The endangered Short-tailed Albatross was once the most abundant of the North Pacific albatross species, numbering more than a million birds. It was decimated by feather hunting at the turn of the 20th Century, and by the late 1940s was thought to be extinct. In the early 1950s, ten pairs were discovered breeding on Torishima. The population has now reached 3,000 individuals, with some birds on the Senkaku Islands, but most still on Torishima.
Conservationists fear an eruption of the active volcano on Torishima could spell disaster. Starting in 2008, an international team led by Japan’s Yamashina Institute began translocating Short-tailed Albatross chicks to Mukojima Island to create a new “insurance” population.
Outside the breeding season, the Short-tailed Albatross ranges along the coasts of eastern Russia, Korea, China, Taiwan, and Alaska and the Hawaiian Islands, and occasionally off the Pacific Coast of North America.
Besides the potential volcano threat on Torishima, the bird is vulnerable to rats and other predators, but the biggest recent mortality threat is bycatch in longline fisheries. Thousands of miles of fishing lines, carrying hundreds of millions of hooks, are set by longliners throughout the world’s oceans each year. Albatrosses, petrels, shearwaters, and fulmars are killed when they become attracted to the bait attached to the hooks, and either swallow the hooks or become snagged and pulled under the sea to drown as the lines are set.
ABC has campaigned to end seabird deaths from longlining in U.S. fisheries since the mid-90s. Thanks to publications such as ABC’s report: Sudden Death on the High Seas – Longline Fishing, a Global Catastrophe for Seabirds and subsequent advocacy efforts by ABC and others, the North American fleets have begun to use bycatch avoidance techniques, and seabird deaths in Hawai’i and Alaska are down by up to 85%. However, a stark reminder of the threat resurfaced when two Short-tailed Albatrosses were killed by longliners in Alaskan waters last September.
