The Chatham Albatross (Thalassarche eremita) is a medium-sized black-and-white New Zealand. It is sometimes treated as a subspecies of the Shy Albatross T. cauta.
The islet on which this albatross breeds has undergone a significant decline in habitat condition, the bird is therefore listed on the IUCN Red List as Critically Endangered. The current population is estimated at 11000.
