Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
Blue Jay
Deciduous and mixed forests, parks, and suburban areas. Highly adaptable to human-modified landscapes.
Song & Call Comparison

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.
Blue Jay
A harsh, ringing 'jaay-jaay-jaay'. Also mimics Red-tailed Hawk and other species convincingly. Gives soft, liquid 'bell' calls and gurgling whispers in flocks.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.
Blue Jay
Eastern and central North America from southern Canada to the Gulf Coast. Some populations migrate irregularly.

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.
Blue Jay
어치는 화려한 깃털과 큰 울음소리로 알려진 까마귀과의 대담하고 지능적인 구성원입니다. 가을마다 수천 개의 도토리를 저장하기 때문에 참나무 나무의 중요한 산포자입니다. 복잡한 사회 행동으로 먹이통에서 다른 새들을 겁주기 위해 매의 울음소리를 흉내 내기도 합니다.
