Antarctic Skua

The Brown Skua , also known as the Antarctic Skua, Southern Great Skua, Southern Skua, or Hākoakoa , is a seabird that breeds in the sub-Antarctic and Antarctic zones and moves further north when not breeding. Its taxonomy is highly complex and a matter of dispute, with some splitting it into two or three species: Falkland Skua , Tristan Skua , and Subantarctic Skua . To further confuse, it hybridizes with both the South Polar and Chilean Skuas, and the entire group have been considered subspecies of the Great Skua, a species otherwise restricted to the Northern Hemisphere. It feeds on fish , small mammals, scraps, chicks, eggs and carrion.

The Antarctic Skua is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.

Antarctic skuas breed on most of the southern islands and may be distributed as far north as the subtropics, while South Polar skuas occur primarily on the Antarctic continent, although sightings have been recorded as far north as Greenland and the Aleutian Islands. South Polar skuas are often seen following ships at sea. In winter after the breeding season, both skua species migrate northward spending most of their time at sea. More

The Antarctic skua (Catharacta maccormicki) is the size of a largish gull. They nest all around continental antarctica and breed into the deep south. They are excellent fliers and have occasionally been sighted deep in the interior hundreds of miles from anything other than ice. More

Above is the Antarctic Skua, which is an aggressive bird that hunts it's prey. They are known for raiding colonies and attacking baby penguins, earning their nickname, 'raptor of the south'. On the left is Antarctica's wild side; a giant petrel eating a baby penguin. While the petrel was eating several other penguins gathered around and would chase the petrel away, but he would always return. The giant petrel is the largest of the almost 100 different species of petrels. More
