Size Comparison
Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
Demoiselle Crane
Dry grasslands, savannas, and semi-desert. Nests on the ground in open country, often near water. Winters in agricultural fields.
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.
Demoiselle Crane
A high-pitched, bugling 'karr-r-r' in flight. Also gives softer clucking and purring contact calls. Migrating flocks produce a continuous musical babbling audible from great distance.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.
Demoiselle Crane
Central Eurasia from the Black Sea to Mongolia and northeastern China. Winters in India and sub-Saharan Africa.

About These Birds
African Penguin
南アフリカ西部沿岸とその島嶼に生息するペンギン（体長60〜70cm）。黒い背中と白い腹に黒い縦縞、眼上部のピンクの皮膚が特徴的。Spheniscus demersus（アフリカペンギン）はロバのような「ブレイヤー」という鳴き声から「ジャッカスペンギン」とも呼ばれる。過去1世紀で個体数が97%以上減少し、絶滅危惧種に指定されている。Spheniscidae科。
Demoiselle Crane
The demoiselle crane is the smallest crane species but undertakes one of the most grueling migrations, crossing the Himalayas at altitudes over 8,000 meters to reach wintering grounds in India. Named for its elegant appearance by Marie Antoinette, it is the second most abundant crane species in the world.
