Synonyms: Diomedea epomophora epomophora; Diomedea epomorpha; Diomedea epomorpha epomorpha

Wikipedia Abstract

The southern royal albatross (Diomedea epomophora) is a large seabird from the albatross family. At an average wingspan of above 3 m (9.8 ft), it is one of the two largest species of albatross, together with the wandering albatross. Recent studies indicate that the southern royal albatross may, on average, be somewhat larger than the wandering albatross in mass and wingspan, although other sources indicate roughly similar size for the two species.
