白头海雕

白头海雕是美国国鸟，也是美国生态保护史上的成功案例，曾因滴滴涕（DDT）的广泛使用而濒临灭绝，经保护措施的实施后种群数量已显著恢复。该物种在IUCN红色名录中被评估为无危（LC），以白色头颈和尾羽与深棕色体羽形成的鲜明对比为主要识别特征。它们主要以鱼类为食，也会捕食哺乳动物和腐肉。

Monarch

作为世界上最令人叹为观止的迁徙昆虫之一，帝王蝶（Danaus plexippus）在北美北部繁殖地和墨西哥山地森林越冬地之间进行多代往返迁徙，距离长达 4,800 千米。鲜艳的橙黑翅膀警告捕食者：其毒性来自幼虫期取食的乳草。由于繁殖地丧失、农药和气候变化，越冬种群自 1990 年代以来已减少 80% 以上，被列为濒危物种。
