ハクトウワシ

アメリカの国鳥であり保全の成功を象徴するハクトウワシは翼開長が最大2.4 mに達し、北米全域の水辺近くの森林や湿地に生息する。強力な空中捕食者兼腐肉食者で魚を主食とするが、水鳥や腐肉も捕食する。DDT汚染と狩猟によって1960年代にほぼ絶滅に瀕したが、農薬の使用禁止と絶滅危惧種法の施行により劇的に回復した。

Clouded Leopard

最大26kgまで成長する中型の野生ネコであるウンピョウは、ヒマラヤ東部から東南アジアを経てボルネオに至る熱帯・亜熱帯の森林に生息します。独特の雲状の被毛模様から名付けられたこの種は、野生ネコの中で頭骨サイズに対して最も長い犬歯を持ち、木を頭から下に降りることができる優れた登攀者です。森林伐採により危急（VU）種とされていますが、総個体数は十分に把握されていません。
