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。

elk

アカシカとも呼ばれるエルク（Cervus elaphus）は、枝角を持つ雄が最大240kgに達するシカ科最大種の一つです。ヨーロッパ、アジア、北アメリカの温帯林や草原に分布し、歴史的には個体群が別の亜種として区別されていました。雄は毎年枝角を落として再生させ、秋の繁殖期には激しい鳴き声競争を繰り広げます。分布域全体にわたって重要なジビエ動物であり、保全対象種です。
