The Wanering Albatross (Diomedea exulans), is a large seabird from the family Diomedeidae which has a circumpolar range in the Southern Ocean. It was the first species of albatross to be described, and was long considered the same species as the Tristan Albatross and the Antipodean Albatross (in fact a few authors still consider them all subspecies of the same species). Together with the Amsterdam Albatross it forms the Wandering Albatross species complex. The Wandering is the largest member of the genus Diomedea (the great albatrosses), and is one of the best known and studied species of bird in the world.
