Size Comparison
Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
House Sparrow
Closely associated with human habitation. Found in cities, towns, farms, and any built environment. Rarely found far from people.
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.
House Sparrow
Monotonous series of chirping 'cheep' and 'chirrup' notes. Male gives 'chilp' song repeatedly. Flocks produce constant chirping chatter. No melodic song; purely functional calls.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.
House Sparrow
Native to Europe, Asia, and North Africa. Introduced to every continent except Antarctica, making it the most widely distributed wild bird.

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。
House Sparrow
家麻雀是全球分布最广的鸟类之一，与人类关系极为密切。雄鸟头顶灰色，喉部黑色，翅具栗色。广泛分布于城市、农村和郊区，以谷物、种子和昆虫为食。因人类扩张而随之传播至世界各地，但近年来在某些地区种群下降明显。
