Skua find the Antarctic beaches -- where they breed -- to be a natural habitat for them.
The skua bird is sometimes called a scavenger.

i believe they live in Antarctica where it is cold
The skua is considered a scavenger bird and they can be aggressive.
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.

The scientific or taxonomic name would be Catharacta antarctica.
These days, Skua have learned to hang around scientific station garbage areas where discarded food from humans is generally plentiful. Skua can live for 25 years, so their habit of feeding in these ways can be learned and practiced. Skua also feed on breeding penguin colonies -- capturing eggs and unprotected checks to feed their own young. Unprotected sea mammal pups are also targets for Skua.
Penguins breed on Antarctica's beaches because there are no natural land predators there. Except for other breeding birds, such as skua, which can attack penguin checks and kill them in order to feed their own young.
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.
Skua are well adapted to survive in Antarctica, with their layer of fat next to their skin. As well, their webbed feet toes end in talons, so they can feed on other birds, especially eggs and chicks. They have also discovered the research station garbage dumps and have learned how to feed from them. Some tagged skua have been known to live for 25 years in Antarctica, or more.
