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。
Guadalupe Murrelet
Guadalupe Murrelet, 22–24 cm, breeds only on Guadalupe Island off Baja California. Very similar to Scripps's Murrelet but with more extensive white on the face. Critically Endangered; fewer than 1,000 individuals; nesting habitat threatened by feral cats and goats (now being controlled). Piscivore.
