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。

Craveri's Murrelet

Craveri's Murrelet, 21–23 cm, breeds on Gulf of California islands, dispersing into the Pacific after breeding. Darkest Synthliboramphus murrelet; less white on face than Scripps's. Near Threatened; small population threatened by introduced predators on nesting islands and bycatch in gill nets.
