An adult Brown Skua (Catharacta antarctica) on South Georgia Island in the Southern Ocean This skua is often referred to as Antarctic Skua (or vice versa); the taxonomy of Skuas is still a matter of dispute. Other names (probably owing to the high level of hybridization in this species) include Southern Great Skua, Southern Skua or Subantarctic Skua.
