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。

帝企鹅

帝企鹅是世界上体型最大的企鹅，身高可达1.2米，体重达45千克，栖息于南极大陆极端恶劣的环境中。它们在隆冬的黑暗中、零下60°C以下的严寒里繁殖，雄鸟将唯一的蛋置于脚背上，藏于育卵囊下孵化长达65天，而雌鸟则在此期间出海觅食。数千只帝企鹅组成的群体通过循环交换位置、使个体轮流经过温暖的核心区域这一抱团取暖行为，堪称合作生存的典范。
