Black-footed albatross

The black-footed albatross (''Phoebastria nigripes'') is a large seabird of the albatross family Diomedeidae from the North Pacific. All but 2.5% of the population is found among the Northwestern Hawaiian Islands. It is one of three species of albatross that range in the northern hemisphere, nesting on isolated tropical islands. Unlike many albatrosses, it is dark plumaged.
==Taxonomy==
Black-footed albatrosses are a type of albatross that belong to Diomedeidae family and come from the Procellariiformes order, along with shearwaters, fulmars, storm petrels, and diving petrels. They share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns. Although the nostrils on the albatross are on the sides of the bill. The bills of Procellariiformes are also unique in that they are split into between seven and nine horny plates. Finally, they produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. This is used both against predators and as an energy rich food source for chicks and for the adults during their long flights.〔Double, M. C. (2003)〕 They also have a salt gland that is situated above the nasal passage that helps desalinate their bodies, to compensate for the high amount of ocean water that they imbibe. It excretes a high saline solution from their nose.〔Ehrlich, Paul R. (1988)〕
The specific epithet of ''nigripes'' is derived from two Latin words, ''niger'' meaning "black", and ''pes'' meaning "foot".〔Gotch, A. F. (1995)〕
