Brown skuas are masters of piracy, they often feed by stealing partially digested fish from the the beaks of other birds. Their victims are typically terns or penguins, though other fish-eating species are also pursued until they disgorge their catches. The fact that skuas are swift and agile fliers (and that they sometimes gang up on a single victim) aid in their success rate.

In addition to fish, skuas also eat other birds, small mammals, eggs and carrion. They are the primary predators of the eggs of the [[Antarctic tern]].
