恺木纹霸鹟

桤木纹霸鹟（Empidonax alnorum）在IUCN红色名录中被评估为无危（LC），繁殖于北美洲北部的桤木和柳树丛中，冬季迁徙至南美洲越冬。该物种与柳纹霸鹟（E. traillii）外形极为相似，主要通过鸣叫声加以区分，是鸟类学研究中鉴别难度较高的物种之一。种群数量目前保持稳定。

gray wolf

灰狼是分布最广的野生犬科动物，分布范围从北美横跨欧亚大陆，栖息于冻原、森林和草原等多种生境。高度社会化的动物，以由占优势的繁殖对领导的家族群体生活。作为关键捕食者，狼调节猎物种群并深刻影响生态系统结构，黄石公园的重引入项目对此有充分证明。曾遭到严重迫害，但目前许多地区的种群正在恢复。
