Size Comparison
Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
Common Ostrich
Open arid and semi-arid habitats including savannas, Sahel, and dry woodlands across Africa.
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.
Common Ostrich
Male produces a surprisingly deep, resonant booming roar — remarkably lion-like. Also gives whistling and hissing sounds. Females and chicks emit softer grunts and squeaks.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.

Sub-Saharan Africa. Formerly also found in the Middle East and parts of Asia. Farmed worldwide.

Males have black body plumage with white wing and tail feathers. Females and immatures are grey-brown. Bare skin on the neck and thighs varies from pink to blue.
Broad, flat bill adapted for an omnivorous diet
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.
Common Ostrich
The common ostrich is the world's largest living bird, standing up to 2.7 meters tall and weighing up to 145 kg. Despite being flightless, it is the fastest bird on land, sprinting at speeds up to 70 km/h. Ostrich eggs are the largest of any living bird, weighing about 1.4 kg each.
