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。

紅領綠鸚鵡

亚历山大鹦鹉（Psittacula krameri）是世界上分布最广、最具入侵性的鹦鹉之一，原产于撒哈拉以南非洲和南亚，但从逃逸笼鸟发展出来，已在包括欧洲、北美、日本和澳大利亚在内的35个以上国家建立了大型野化种群。雄鸟具有独特的粉红和黑色颈环。适应力强、繁殖力高，在伦敦、阿姆斯特丹、布鲁塞尔等城市中野化种群急剧增加，形成庞大的栖息群落，并与本土洞巢鸟类展开竞争。
