The scientists estimated the 2011 tsunami flooded 26 to 52 percent of the Black-footed albatross
nests concentrated on the coast of islands and that across the four islands more than 275,000 Black-footed and Laysan albatross and Bonin petrel nests were flooded.
The Laysan Albatross, Black-footed Albatross
, and the Short-tailed Albatross can be found on the island.
Albatross takes (Laysan albatross, Phoebastria immutabilis; black-footed albatross
, Phoebastria nigripes; and short-tailed albatross combined) declined from 1,051 birds per year during 1993-2000 to 185 birds per year during 2002-06 (Fig.
Levels of the metal's toxic organic form, methylmercury, have been increasing in the black-footed albatross
for more than a century, research has shown.
Present status and epidemiological investigation of Carios (Ornithodoros) capensis in the colony of the black-footed albatross
Diomedea nigripes on Tori-shima, Izu Islands, Japan [in Japanese].
University of California, Santa Cruz ecologist Myra Finkelstein and colleagues measured concentrations of DDT in blood samples taken from the Laysan albatross and the endangered black-footed albatross
, both of which live in open oceanic areas.
One species in particular, the black-footed albatross
, has recently joined the list of species that may become extinct in the near future because so many are being killed by longliners.
High levels of PCBs have even been found in the eggs and tissue of the black-footed albatross
on the isolated Midway Atoll in the South Pacific.
The atoll's three tiny islands have been eerily devoid of their roughly one million Laysan and black-footed albatross
residents since early August, when the last of the seabirds took off at the end of their eight-month breeding season.
The Oregon Coast will be the first birding trail in the country to offer pelagic sites, accessible only by boat to view seagoing birds such as the black-footed albatross
, sooty shearwater and fork-tailed storm-petrel - "birds you'll never see standing on the mainland," Grafe said.
Available estimates for total albatross mortality in North Pacific pelagic longline fisheries, along with population modeling experiments on the Black-footed Albatross
, highlight the concern that mortality in longline fisheries threatens the existence of Black-footed Albatrosses
and may pose a significant threat to the other North Pacific albatross species.
