About These Birds

Atlantic Puffin

「海のピエロ」とも呼ばれるニシツノメドリは、北海の崖に穴を掘って営巣する魅力的な海鳥。口蓋に後ろ向きの棘があるため、一度に12匹もの魚を横向きにくわえて運ぶことができる。気候変動と乱獲による餌不足が脅威となり、個体数が減少している。

Great Auk

Great Auk was the Northern Hemisphere's giant flightless auk, 75–85 cm, hunted to extinction in 1844. The last pair was killed on Eldey Island, Iceland. Black above, white below with a white oval eye patch; vestigial wings. Spent most of its life at sea; bred colonially on Atlantic islands and rocks.
