Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
Northern Cardinal
Woodland edges, thickets, gardens, and suburban areas. Prefers dense shrubby habitats for nesting.

Northern Cardinal
Loud, clear whistled phrases: 'cheer-cheer-cheer' and 'birdy-birdy-birdy'. Both male and female sing; female song is softer. Alarm is a sharp metallic 'chink'.

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。
Northern Cardinal
The northern cardinal is the state bird of seven US states, more than any other species. Unlike many songbirds, both males and females sing, often in duets. Cardinals do not migrate and their brilliant red plumage against winter snow makes them a favorite among backyard birdwatchers.
