Size Comparison
Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
European Robin
Woodlands, hedgerows, parks, and gardens across Europe. Remarkably tame around humans, especially in Britain.
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.
European Robin
Exquisite, melancholic melody of thin whistled phrases, rising and falling softly. Rich, warbling song year-round; both sexes sing. Alarm call is a sharp 'tic-tic-tic'.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.
European Robin
Europe, western Asia, and parts of North Africa. Northern populations migrate south in winter; western European populations are largely resident.
