Size Comparison
Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
Barn Swallow
Open farmland, meadows, and areas near water. Nests almost exclusively in human-made structures such as barns, bridges, and eaves.
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.
Barn Swallow
A rapid, twittering song: a long stream of 'vit-vit-vit' and rolling chirps. Also gives a sharp 'vit' flight call. Song can last many minutes without pause. Musical and liquid.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.
Barn Swallow
Breeds across the Northern Hemisphere in North America, Europe, and Asia. Winters in South America, Africa, and South Asia.

Metallic blue-black upperparts, rufous forehead and throat, and pale buff to rufous underparts. Deeply forked tail with elongated outer streamers.
Short, wide, flat black bill adapted for catching insects in flight
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。
Barn Swallow
The barn swallow is the most widespread swallow species in the world and has one of the longest migrations of any passerine. Its arrival signals spring across the Northern Hemisphere, inspiring cultural references from ancient Greece to modern poetry. Barn swallows have become almost entirely dependent on human structures for nesting.
