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。

plains zebra

最も個体数の多い野生の馬科動物であるサバンナシマウマ（Equus quagga）は、東アフリカと南アフリカの草原およびサバンナに小さな家族グループから大規模な集団まで様々な形で生息する。個体ごとに独特の白黒の縞模様は、捕食者を混乱させ、吸血昆虫を防ぎ、個体識別を助けると考えられている。シマウマはライオン、ハイエナ、ワニの主要な餌となり、サバンナの食物網を支える。
