Chatham Island albatrossThalassarche eremita
The Chatham albatross is endemic to New Zealand, with approximately 4,500 pairs breeding annually on the Pyramid (a small island that is part of the Chatham islands archipelago). Previously considered as Critically Endangered on the IUCN red list, its status was changed to Vulnerable in 2010 because its population appears to be stable. The Chatham albatross has a much darker head and brighter yellow bill than the Salvin's albatross. However, at sea some misidentifications may occur.
