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。

淺灰食籽雀

灰色食籽鸟是一种具有锥形喙和灰褐色羽毛的小型、不显眼的食籽鸟，栖息于从哥伦比亚和委内瑞拉到特立尼达和圭亚那的南美洲北部开放草地、热带稀树草原和稻田。雄鸟呈中等灰色，翅膀较深；雌鸟呈棕色条纹。高度群居，在草籽上形成大型觅食群。与许多草地食籽鸟一样，灰色食籽鸟在生态上了解甚少，面临原生草地农业转化带来的持续压力。
