Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.

Wooded lakes, rivers, and ponds surrounded by dense forest. Unlike most ducks, regularly perches in trees and nests in tree cavities.
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.
Mandarin Duck
Male gives a low whistled 'hib' or 'weep'. Female utters a soft quacking 'kek'. Generally quiet and secretive. No loud territorial song; vocalizations subtle and brief.
Geographic Range & Migration

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。
Mandarin Duck
The mandarin duck is widely considered the most beautiful duck in the world. In East Asian culture, mandarin ducks symbolize love and fidelity because they form strong pair bonds. Unlike most ducks, mandarins nest in tree holes up to 9 meters above the ground, and day-old ducklings must leap to the ground.
