Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
Emperor Penguin
Antarctic pack ice and surrounding Southern Ocean. The only penguin species that breeds during the Antarctic winter.
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.
Emperor Penguin
Loud, resonant trumpeting calls used for individual recognition in dense colonies. Each bird's call is unique in frequency. Also gives softer contact 'braying' notes.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.
Emperor Penguin
Antarctic continent and surrounding sea ice. Breeding colonies are found along the entire Antarctic coastline.

Sturdy, pointed, black bill with a grey band near the tip
Emperor Penguin
Black head, chin, and dorsal side with white belly. Bright yellow-orange ear patches fade to pale yellow on the upper breast.
Long, slightly decurved bill — black with orange or pink mandible stripe
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.
Emperor Penguin
The emperor penguin is the tallest and heaviest of all penguin species. They breed in the harshest conditions on Earth, enduring Antarctic winter temperatures of -60 C and wind speeds of 200 km/h. Males incubate the single egg on their feet under a brood pouch for about 65 days while fasting.
