Size Comparison
Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
Black Swan
Lakes, rivers, swamps, and coastal waters across Australia. Also found in ornamental lakes in parks.
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.
Black Swan
Gives a musical bugling 'boo-boo-boo' in flight and softer honking on water. Less vocal than Mute Swan; produces a baying call when alarmed. Wings whistle softly in flight.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.
Black Swan
Australia, primarily in the southeast and southwest. Introduced populations in New Zealand, Japan, and western Europe.

About These Birds
African Penguin
非洲企鹅（学名Spheniscus demersus）是非洲大陆唯一原生的企鹅物种，又称公驴企鹅，因发出类似驴叫的叫声而得名。体重2-3千克，体长60-70厘米。濒危物种（IUCN红色名录），种群数量持续下降，主要受过度捕捞、石油污染和气候变化威胁。繁殖于南非和纳米比亚沿海岛屿。
Black Swan
The black swan was once considered impossible by Europeans who believed all swans were white, making it a famous philosophical example of inductive reasoning failure. It is the state emblem of Western Australia. Black swans form lifelong pair bonds and both parents share in incubation and care of cygnets.
