Large populations are found at South Georgia, Falkland Islands, and Iles Kerguelen although their breeding distribution is circumpolar. An orange bill and a white stroke behind its eye distinguish the black and white gentoos from the smaller adelie and chinstrap species. Long stiff tail feathers stick out behind as they walk, often cocked up in the water, no other penguin has such a prominent tail. They breed in winter at the more northerly sub-Antarctic islands, laying two eggs as early as July. Can dive over 300' though most prey dives are shallower. Most dives last only half a minute.
