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.
Eastern Bluebird
A rich, melodious warbled 'chur-wi, tur-a-lee' song. Both sexes sing. Call is a soft, musical 'turee'. Song is gentle and flute-like, suggesting a small thrush. Given from exposed perch.

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.
Eastern Bluebird
동부파랑새는 북미에서 행복의 상징으로 사랑받는 새이다. 한때 농약과 집 짓기 경쟁으로 급감했지만, 둥지 박스 설치 운동 덕분에 개체군이 크게 회복되었다. 수컷은 짙은 파란 윗면과 녹슨 붉은 가슴을 자랑한다.
