Breeding Distribution and Status of Marine Birds in the Aleutian Islands, Alaska
U.S. Fish and Wildlife Service Kailua, Hawaii
U.S. Fish and Wildlife Service Adak, Alaska
Seabird population estimates are generally lacking for the 1,800-km-long Aleutian Islands. Only the locations of the larger colonies are known, and for these there are only imprecise estimates of colony sizes and often even of species composition. Changes in the status of several species and populations resulting from geologic and marine actions and from human intrusions are evident. Accounts are given for 25 species of marine birds breeding in these islands.
The 1,800-km-long chain of islands known as the Aleutians provides nesting habitat for various species of marine birds, including three species of Procellariiformes and three of cormorants (_Phalacrocorax_ spp.), one species of gull _(Larus glaucescens)_, both kittiwake species (_Rissa_ spp.), two species of terns (_Sterna_ spp.), and at least 13 species of alcids.
