First a little information, before I post a very odd story:
Skuas (pronounced /ˈskjuəz/) are seabirds in the family Stercorariidae.
Skuas are related to gulls, waders, auks and skimmers.
You can find Skuas in both the polar regions, though they are different subspecies.
The Brown Skua (Catharacta antarctica) 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. The New Zealand Māori call it Hākoakoa. It breeds circumpolar in the sub-Antarctic and Antarctic zones. It feeds on fish (often stolen from other birds), small mammals, scraps, chicks, eggs and carrion.
The bird in this story looks to me as a Brown Skua, though I may be corrected, so I left the topicname general.
However, have a read in this animal behaviour story
