Breeding information

Breeding season: ca. Dec - Feb Eggs: 2 Incubation period: 34 -36 days Fledging age: ca. 30 days

Gentoo Penguin chicks leave their nests at about 30 days of age. They then form "creches" or rookeries, before they go out to sea at an age of ca. 80-100 days.

Nest building: Female & male Incubation: Female & male Dependent care: Female & male

Male and female Gentoo Penguins incubate alternatingly, each bird staying on the nest one day at a time, while the other leaves in search of food.
