Synonyms: Diomedea chrysostoma; Diomedea chrysostoma chrysostoma

Wikipedia Abstract

The grey-headed albatross (Thalassarche chrysostoma) also known as the grey-headed mollymawk, is a large seabird from the albatross family. It has a circumpolar distribution, nesting on isolated islands in the Southern Ocean and feeding at high latitudes, further south than any of the other mollymawks. Its name derives from its ashy-grey head, throat and upper neck.
