Size Comparison
Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
Emu
Open grasslands, savanna woodlands, scrublands, and semi-arid plains across Australia. Avoids dense forest and true desert.
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.
Emu
Deep, resonant booming grunt 'e-moo', often repeated 3 times. Females give a deep drumming call produced by an inflatable throat pouch. Generally low-pitched and far-carrying.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.
Emu
Throughout mainland Australia. Absent from Tasmania, where the Tasmanian emu was driven to extinction by 1850.

Sturdy, pointed, black bill with a grey band near the tip
Emu
Shaggy grey-brown plumage with double-shafted feathers giving a loose, hair-like appearance. Bare blue skin on the face and neck.
Broad, flat, dark grey 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.
Emu
The emu is the second-tallest living bird and the largest bird native to Australia. It is the only bird with calf muscles, enabling powerful running at up to 50 km/h. In the famous Emu War of 1932, the Australian military was deployed against crop-raiding emus — and the emus arguably won.
