Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.

Lawns, parks, gardens, farmland, and forest edges. One of the most familiar birds in suburban North America.
Song & Call Comparison
African Penguin
A loud, donkey-like braying 'waaah-waaah' — hence its nickname 'jackass penguin'. Also gives softer grunts and contact calls at the colony. Highly vocal on breeding beaches.
American Robin
A clear, caroling song of 2-3 note phrases: 'cheerily, cheer-up, cheerio'. Sings from dawn perches. Sharp 'tut-tut-tut' alarm call and thin 'seeee' flight note.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.
American Robin
North America from Alaska and Canada to Mexico. Northern populations migrate south in winter; southern populations are largely resident.

About These Birds
African Penguin
The African penguin is the only penguin species native to the African continent, also called the jackass penguin for its donkey-like braying call. Their population has plummeted over 95% since pre-industrial times due to egg collection, oil spills, and competition with commercial fisheries for sardine and anchovy stocks.
American Robin
The American robin is widely regarded as a harbinger of spring across North America. Despite its name, it is a true thrush unrelated to the European robin. American robins produce two to three broods per year and are among the earliest birds to sing in the morning chorus.
