Size Comparison
Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
Downy Woodpecker
Deciduous and mixed forests, orchards, parks, and suburban areas. The most common woodpecker at feeders in North America.
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.
Downy Woodpecker
A sharp 'pik' or 'peek' contact call. Drums on resonant branches with a rapid, light tattoo — softer than larger woodpeckers. Also gives a high descending whinny 'keeer-keeer'.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.
Downy Woodpecker
North America from Alaska and Canada south through the United States, excluding the arid Southwest.

How to Tell Them Apart
African Penguin
Black upperparts and white underparts with a distinctive black horseshoe-shaped band across the breast. Pink patches of bare skin above the eyes help with thermoregulation.
Sturdy, pointed, black bill with a grey band near the tip
Downy Woodpecker
Black and white plumage with a broad white stripe down the back. Black wings with white spots. Males have a small red patch on the nape.
Short, chisel-shaped, dark bill — noticeably shorter than the similar hairy woodpecker
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.
Downy Woodpecker
솜털딱따구리는 북아메리카에서 가장 작고 가장 널리 분포하는 딱따구리이다. 소형 체구 덕분에 더 큰 딱따구리가 접근할 수 없는 가는 나뭇가지와 잡초 줄기에서 먹이를 찾을 수 있다. 솜털딱따구리는 겨울에 혼종 무리에 합류하여 여러 종이 함께 포식자를 감시하는 이점을 얻는다.
