Size Comparison
Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
White-tailed Eagle
Coastlines, large lakes, and rivers with mature trees or cliffs for nesting. Requires large undisturbed areas.
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.
White-tailed Eagle
High-pitched, yelping 'klee-klee' and deep barking 'ra-ra-ra'. Less vocal than Bald Eagle but similar chattering quality. Gives gull-like wailing near nest in breeding season.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.
White-tailed Eagle
Northern Europe and Asia from Greenland and Scandinavia to Japan. Reintroduced to Scotland and Ireland.

Very large, heavy, pale yellow bill
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.
White-tailed Eagle
The white-tailed eagle is Europe's largest eagle and the fourth-largest eagle in the world. Once extinct in Britain, it has been successfully reintroduced to Scotland and Ireland through conservation programs. These powerful raptors can live over 25 years and form lifelong pair bonds.
