The Kelp Gull is a species that occurs on most subantarctic islands and on the northern tip of the Antarctic Peninsula. However, migrants can be found on several parts of Antarctica.
In most parts of the world, large gulls pose a real ID-challenge, often only tried by real experts. This is not the case on Antarctica as there is only one large gull present (except for some real rarities that I’ve never seen there). They breed in or near penguin colonies where they try to steal eggs, grab a chick or scavenge on dead adult penguins, but their main food appears to be limpets.
