Amsterdam albatross  (Diomedea amsterdamensis)

The Amsterdam albatross is an extremely large albatross that breeds only on Amsterdam Island in the southern Indian Ocean (4). When first described in the early 1980s it was believed by some to be a subspecies of the wandering albatross (Diomedea exulans) (5). This ‘great albatross' (Diomedea) breeds in a brown plumage, rather than the more usual white (4). Adults have almost entirely chocolate-brown upper parts, a white face and throat, a broad brown breast-band, a white lower breast and belly, and brown undertail-coverts. The underwing is white, with a dark tip (6).
