Size Comparison
Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
Red-crowned Crane
Freshwater marshes, bogs, and wet grasslands for breeding. Winters in coastal mudflats, estuaries, and rice paddies.
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.
Red-crowned Crane
Spectacular unison 'bugling' call: a clear, resonant, far-carrying trumpet 'kru-ru-ru' given by paired birds simultaneously. Among the most majestic bird calls in Asia.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.
Red-crowned Crane
Eastern Asia — breeds in northeastern China, southeastern Russia, and Hokkaido, Japan. Winters in Korea and eastern China.

About These Birds
African Penguin
아프리카펭귄은 아프리카 대륙에 고유한 유일한 펭귄 종으로, 당나귀 울음소리 같은 울음 때문에 자카스펭귄이라고도 불린다. 남아프리카와 나미비아의 해안과 섬에 서식한다. 현재 멸종 위기종으로, 어업과 서식지 훼손으로 인해 지난 세기 동안 개체수가 급격히 감소했다.
Red-crowned Crane
The red-crowned crane is one of the rarest crane species and a potent symbol of longevity and fidelity in East Asian culture. Their elaborate unison call and dancing displays have inspired art and folklore for millennia. The resident population on Hokkaido, Japan, recovered from about 33 birds in 1952 to over 1,800 today.
