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。

仓鸮

仓鸮（Tyto alba）是地球上分布最广泛的猫头鹰种类，除南极洲外遍布各大洲，栖息于从热带雨林到温带农田的几乎所有生境类型。其心形脸盘可将声音汇集至非对称排列的耳部，使其能在完全黑暗中仅凭声音定位猎物。它们将猎物整个吞下，再将不可消化的骨骼和毛发压缩成食丸吐出，是农业中珍贵的鼠类防治帮手。
