About These Birds
Atlantic Puffin
대서양퍼핀은 '바다의 광대'라 불리는 매력적인 바닷새로, 북부 해식애의 굴에 둥지를 틉니다. 입천장의 뒤를 향한 가시 덕분에 한 번에 12마리의 물고기를 부리에 횡으로 물 수 있습니다. 기후 변화와 남획이 먹이 공급을 위협하면서 개체수가 감소하고 있습니다.
Cassin's Auklet
Cassin's Auklet, 21–23 cm, is a small, almost entirely dark grey auklet breeding in burrows on rocky North Pacific islands from Baja California to the Aleutians. Feeds almost exclusively on zooplankton — euphausiids and copepods — at night. Highly colonial; winters near shore.
