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。
ヘビクイワシ
The secretary bird is the only raptor that hunts primarily on foot, striding through grasslands on crane-like legs up to 1.2 meters tall. Its name may derive from the crest feathers resembling quill pens tucked behind a secretary's ear. The species is classified as Endangered due to habitat loss and decline across much of its range.
