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。

large flying fox

世界最大のコウモリ種で、翼開長は最大1.5メートルに達し、東南アジアからフィリピン・インドネシアにかけての熱帯林に生息する。その名に反して果実と花蜜のみを食べ、熱帯林の樹木にとって不可欠な花粉媒介者・種子散布者となっている。数千頭もの巨大なコロニーでねぐらを作る。食用のための狩猟と生息地破壊により絶滅危惧種に指定されている。
