Abstract We investigated one active and three aban-doned Adélie penguin (Pygoscelis adeliae) colonies in northern Marguerite Bay, Antarctic Peninsula, during austral summer 2000. Extinct colonies were located by ground survey on small islands and recognized by con-centrations of nest pebbles. The c...
