Size Comparison
Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
Red-crowned Crane
Freshwater marshes, bogs, and wet grasslands for breeding. Winters in coastal mudflats, estuaries, and rice paddies.
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.
Red-crowned Crane
Spectacular unison 'bugling' call: a clear, resonant, far-carrying trumpet 'kru-ru-ru' given by paired birds simultaneously. Among the most majestic bird calls in Asia.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.
Red-crowned Crane
Eastern Asia — breeds in northeastern China, southeastern Russia, and Hokkaido, Japan. Winters in Korea and eastern China.

Sturdy, pointed, black bill with a grey band near the tip
Red-crowned Crane
White body plumage with black secondary flight feathers and throat. Bare red crown patch. Black face and neck. One of the most elegant crane species.
Long, straight, olive-green 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.
Red-crowned Crane
The red-crowned crane is one of the rarest crane species and a potent symbol of longevity and fidelity in East Asian culture. Their elaborate unison call and dancing displays have inspired art and folklore for millennia. The resident population on Hokkaido, Japan, recovered from about 33 birds in 1952 to over 1,800 today.
