Size Comparison
Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
Eurasian Wren
Dense undergrowth in woodlands, gardens, hedgerows, and rocky areas. Prefers tangled vegetation close to the ground.
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.
Eurasian Wren
Extraordinarily loud for its tiny size: a rapid, powerful stream of trills, buzzes, and churring phrases. One of Europe's loudest songs by volume relative to body weight.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.
Eurasian Wren
Eurasia from Iceland and western Europe to Japan. The only wren species found outside the Americas.

Eurasian Wren
Warm rufous-brown upperparts with fine dark barring. Pale buffy underparts with barred flanks. Short, often cocked tail.
Thin, slightly curved, dark brown bill
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。
Eurasian Wren
ヨーロッパ最小クラスの鳥の一つで、体の大きさに不釣り合いな大きな声で鳴く。民話では鳥の王様とされる。
