The Amsterdam albatross or Amsterdam Island albatross, (Diomedea amsterdamensis), is a large albatross which breeds only on Amsterdam Island in the southern Indian Ocean. It was only described in 1983, and was thought by some researchers to be a sub-species of the wandering albatross, D. exulans. BirdLife International and the IOC recognize it as a species, James Clements does not, and the SACC has a proposal on the table to split the species.
The Amsterdam albatross is a great albatross that breeds in brown, rather than in the more usual white, plumage. The adult bird has chocolate brown upper parts and is white on its face mask, throat, lower breast, and belly. It has a broad brown breast band along with brown undertail coverts. Its pink bill has a dark tip and dark cutting edges, and finally, its underwings are white except for the dark tip and the dark leading edge.
