The gentoo penguin is a medium-large penguin of the Antarctic Peninsula and sub-Antarctic islands. It is one of the few Antarctic penguins that is increasing in number, as a warming climate opens new breeding sites.
Interesting facts
- Gentoos have a white stripe over each eye and a bright orange bill.
- Males offer pebbles to females as part of courtship.
- Gentoo populations are increasing and spreading south on the Antarctic Peninsula.
- Recent research suggests gentoos may be four separate species in different regions.
- The Falkland Islands hold a large share of the world’s gentoos.
- Gentoos may make hundreds of dives a day when feeding.
Behaviour
Gentoos usually feed close to their colonies and return each day. They are less migratory than other Antarctic penguins.
Breeding and young
Pairs build nests of stones, moss and grass and lay two eggs. Both parents incubate them for about five weeks, and chicks fledge after about three months.
Threats and conservation
Human disturbance, oil pollution, bird flu and changes in food supply.
