The Antarctic Skua is an excellent flier and very acrobatic. They have a reputation for being very aggressive and often feed by scaring other birds in leaving their food or even regurgitating what they have already eaten. They will even attack another bird that is up to three times heavier than themselves. At other times they also eat fish, offal, and carrion. In the Southern oceans and Antarctica, some skua will readily scavenge the carcasses of penguins and pinnipeds, sometimes taking live penguin chicks.
