Gentoo Penguin
Bright bill, white eye-patch, and rocket swims — the fastest penguin in Antarctic waters.
Least Concern
Pygoscelis papua
Overview
Gentoo penguins nest on subantarctic islands and the Antarctic Peninsula, building pebble scrapes in colonies and commuting to krill-rich seas. A white blaze behind each eye and an orange-red bill make them easy to pick from other brush-tailed penguins.
For Antarctica collectors, a gentoo card is a rare polar prize — colourful, athletic, and tied to icy breeding beaches.

Field notes
Field scale for the Gentoo Penguin: height 70-90 cm; weight 4.5-8.5 kg. Typical lifespan: Around 15-20 years in the wild.
When you are scanning habitat, prioritise subantarctic coast, ice-free nesting beach, and krill-rich shelf waters. Those settings are where a clean look and a usable photo are most likely.
Quick ID anchor: Black-and-white brush-tailed penguin with a bright orange-red bill and white eye-to-crown patches. Confirm with behaviour and habitat before you log the discovery.
Diet
Primarily Antarctic krill and other crustaceans, plus fish and cephalopods when available.
Chase prey in short, high-speed underwater pursuits near the colony.
Behaviour
Breed in dense colonies; partners recognize calls and nest sites among hundreds of neighbours.
Build and defend pebble nests; steal stones from rivals when unwatched.
How to identify
Black-and-white brush-tailed penguin with a bright orange-red bill and white eye-to-crown patches.
Longer tail and more upright stance than Adélie or chinstrap penguins.
Interesting facts
- 01
Among the fastest underwater penguins, often exceeding 30 km/h.
- 02
White triangular patches run from each eye to the crown.
- 03
Nest scrapes are lined with carefully collected pebbles.
- 04
Main prey includes krill, fish, and small squid.
- 05
Parents share incubation of usually two eggs.
- 06
Colonies can number thousands of breeding pairs.
Conservation status
Gentoo penguins are Least Concern globally, though local colonies can shift with ice, food, and human disturbance. Monitoring on the Antarctic Peninsula tracks climate-linked changes.
