This medium-sized, black-and-white albatross (2) has only recently been considered a distinct species and separate from the shy albatross (Thalassarche cauta) (3). Adults have a pale grey head, throat and upper mantle, paler on the crown, and a dark grey to black back, upperwing and tail. In contrast, the rump and underparts are snowy-white except for a narrow dark border to the underwing and a distinctive black ‘thumbmark' at the base of the underwing's leading edge. The legs, feet and beak are an inconspicuous pale grey, with a pale yellow upper ridge to the upper bill and a dark spot at the tip of the lower bill (2).
