The Antipodean albatross (Diomedea antipodensis) (Māori: Toroa)[4] is a large seabird in the albatross family. Antipodean albatrosses are smaller than snowy albatrosses, and breed in predominantly brown plumage, but are otherwise difficult to distinguish from young snowy albatrosses (snowy albatrosses grow lighter in color with age, while the Antipodean stays darker).
Etymology
Diomedea antipodensis breaks into Diomedea referring to Diomedes, whose companions turned to birds, and antipodensis, the Latin form of the Antipodes Islands, where they are found.[5]
Taxonomy
The Antipodean albatross belongs to the
Subspecies
There are two sub-species; however there was a study in 1998 that suggested splitting this species,[9] though this was not accepted in a 2004 study.[10]

Diomedea antipodensis gibsoni | breeds on the Auckland Islands[2] |
Description

Behaviour
They feed predominantly on cephalopod and to a lesser extent fish[2] (unlike other albatross species they are not recorded eating any crustaceans), and have been recorded visiting the spawning grounds of the giant cuttlefish off New South Wales. They nest on ridges, slopes, or plateaus, and will build their nest in the open or within patchy vegetation, such as tussock grassland.[2]
Conservation
The
Pigs and feral cats are hurting the population on Auckland Island and longline fishing is still impacting them. Recent studies have shown that a rise in Tasman Sea temperature may be impacting gibsoni.[2]
Banding has been an ongoing process, and will continue with satellite tracking of the species. Cattle and sheep have been eradicated from Campbell Island, and all the islands are nature preserves and recently became World Heritage Sites. Cats and pigs need to be removed from the Auckland Islands, the fisheries need to be worked with and the ocean temperature fluctuations need to be studied to help this species survive.[2]
