No animal 'lives' on the continent: it's too cold and there is no food chain to support animal life. All birds that breed on Antarctica's beaches are sea birds, and include penguins, terns, skua and albatross.
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.
Emperor penguins are sea birds, and are part of the natural food chain in the sea. They breed on Antarctica's beaches, because there are no land predators there. However, their chicks are prey to other breeding animals, such as the Skua and seals.
