The only albatross to occur regularly off
the Pacific coast of North America, the Black-footed Albatross
nests on undisturbed sandy shores of remote beaches in the
Hawaiian Islands and a few sites in the Japanese islands and
then wanders widely from the Aleutians south throughout the
northern and central Pacific. Its movements during the nonbreeding
season reflect food distribution and wind. For nesting it
prefers sandy habitat close to the beach. It feeds on fish,
fish eggs, squid, and crustaceans.A long-lived species, it
lays one egg a year.With about 280,000 individuals, its largest
colony is on Laysan Island, with 14,000 to 21,000 pairs.
Oil pollution, drift nets, and longlines
are threats to the bird, the latter particularly since the
bird often scavenges behind ships. This may account for the
fact that counts of nesting birds declined by 19% between
1995 and 2000, since longline fisheries were killing an estimated
4,500 of the species a year. Driftnet fisheries have been
stopped as have long-line fisheries for swordfish in Hawaii
because of their depredations on birds and other non-target
species. New devices on longlines seem to be reducing seabird
deaths as a result of the fishing industry.
