albatross ăl´bətrôs [key], common name for sea birds of the order of tube-nosed swimmers (Procellariiformes), which includes petrels, shearwaters, and fulmars. The wandering albatross, Diomedea exulans, made famous by Coleridge's Rime of the Ancient Mariner, has a wingspread of from 10 to 12 ft (305–366 cm), although the wings are only about 9 in. (22.5 cm) wide. Because of their tapering wing design they excel at gliding and flying. Albatrosses eat mainly fish, floating carrion, and refuse. Most albatrosses are found in the South Pacific region, e.g., the wandering and the sooty species; a few, the black-footed (D. nigripes), the short-tailed, and the Laysan (D. immutabilis) albatrosses, regularly frequent the N Pacific.

Albatrosses have unique courtship behavior. They groan, scrape their bills, and dance about awkwardly, before pairing and mating occurs. They are colonial breeders, the female laying her single white egg in crude nests on the ground. Both sexes incubate the egg; incubation takes from two to three months. Albatrosses have few natural enemies, with the exception of humans. They were slaughtered for their feathers and wings in the 19th cent., and used in millinery and as swansdown pillow stuffings.

Albatrosses are classified in the phylum Chordata, subphylum Vertebrata, class Aves, order Procellariiformes, family Diomedeidae.
