Crescent-shaped Half Moon Island, lies on the eastern side of the Livingston Island, South Shetlands. Here you can see Weddell and Elephant seals, as well as Gentoo penguins along the shore and a large Chinstrap penguin colony (with approximately 3,300 breeding pairs) further up the hill. It is a home to breeding Antarctic terns, skuas, blue-eyed shags, kelp gulls, and Wilson's storm-petrels. Also there is the Argentine Cámara Station located on the south-west side of the island.
