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.
Arctic Tern
북극제비갈매기는 모든 동물 중 가장 긴 이동 기록을 보유하고 있어, 매년 북극에서 남극까지 약 7만 km를 왕복합니다. 약 30년의 수명 동안 달을 세 번 왕복하는 거리를 날아다닙니다. 지구상 어떤 생물보다 많은 일광을 경험하는 놀라운 새입니다.
