Endangered
Atlantic yellow-nosed albatross
Thalassarche chlororhynchos
The Atlantic yellow-nosed albatross is a large seabird in the albatross family Diomedeidae.
Appearance
The Atlantic yellow-nosed albatross averages 81 cm (32 in) in length. It is a typical black and white mollymawk with a grey head and large eye patch, and its nape and hindneck are white. Its bill is black with a yellow culminicorn and a pink tip.
Published measurements include mass about 2.06.
Range and habitat
Atlantic yellow-nosed albatrosses nest on islands in the mid-Atlantic, among them Tristan da Cunha (Inaccessible Island, Middle Island, Nightingale Island, Stoltenhoff Island) and Gough Island. At sea they range across the south Atlantic from South America to Africa between 15°S and 45°S.
Gough Island has 5,300 breeding pairs, between 16,000 and 30,000 breeding pairs on Tristan da Cunha Island, 4,500 on Nightingale Island, between 100 and 200 pairs on Middle Island, and 500 pairs on Stoltenhoff Island, and 1,100 on Inaccessible Island. Efforts to help conserve this bird are underway, with counting of the birds on Gough Island.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Breeding
Like all mollymawks they build pedestal nests of mud, peat, feathers, and vegetation to lay their one egg in.
In crisis
The IUCN list this species as endangered, with an occurrence range of 16,800,000 km2 (6,500,000 sq mi) and a breeding range of 80 km2 (31 sq mi). A 2001 population estimate breaks down the population and shows some trends. This population estimate was done in 1983, however and is outdated.
The largest threat is from longline fishing, as harvesting of chicks and adults has been outlawed. The Tristan da Cunha population is being remotely tracked and counted, and the South East Atlantic Fisheries Commission has passed a resolution that all fishing vessels use a tori line and drop lines at night.
