About Thalassarche chlororhynchos (Gmelin, 1789)
The Atlantic yellow-nosed albatross (Thalassarche chlororhynchos) has an average length of 81 cm (32 in). It is a typical black-and-white mollymawk with a grey head and a large eye patch; its nape and hindneck are white. Its bill is black, with a yellow culminicorn and a pink tip. It has a blackish grey saddle, tail, and upperwing, while its underparts are predominantly white. A narrow black margin appears on its underwing and primaries. Juvenile Atlantic yellow-nosed albatrosses are similar to adults, but have a white head and a black bill. This species can be told apart from the Indian yellow-nosed albatross by its darker head. Compared to other mollymawks, it can be distinguished by its smaller size (with particularly narrow wings) and the thin black edging on the underwing. The grey-headed albatross shares a similar grey head, but has more extensive, less well-defined black markings around the edge of the underwing. Salvin's albatross also has a grey head, but has much broader wings, a pale bill, and even narrower black borders to the underwing. Atlantic yellow-nosed albatrosses nest on islands in the mid-Atlantic, including the Tristan da Cunha archipelago (Inaccessible Island, Middle Island, Nightingale Island, Stoltenhoff Island) and Gough Island. When at sea, their range spans the south Atlantic from South America to Africa, between 15°S and 45°S.
