The South Polar skua of Antarctica is known as the world's most southerly bird. They generally lay two eggs which hatch in late December - late January after an incubation period of 24 to 34 days.
Around McMurdo Station, there are banded skua documented to have survived more than 25 years.
The average life span of the skua is roughly 11 years, but can be longer in the right environment. Most skuas, however, don't live until the 11 year mark because of their violent, aggressive lifestyles.
Skua find the Antarctic beaches -- where they breed -- to be a natural habitat for them.
The skua bird is sometimes called a scavenger.

Antarctic skua breed on Antarctica's beaches and otherwise live elsewhere. Skua chicks, like all bird chicks, are subject to being preyed upon by any raptor interested in feeding its young.
