橡树啄木鸟

橡实啄木鸟（Melanerpes formicivorus）是北美洲西部橡树林中的标志性鸟类，在IUCN红色名录中被评估为无危（LC）。该物种以集体储存橡实的独特行为著称，会将成千上万颗橡实塞入树皮缝隙中作为越冬食物储备。其社会性群居行为和协作繁殖体系在鸟类学研究中颇受关注。

koala

澳大利亚东部和东南部的标志性有袋类动物，体重最大可达15千克，为了节省低热量桉树叶食物所提供的能量，每天最多睡眠22小时。高度特化，能够处理会致大多数其他哺乳动物死亡的有毒桉树成分，拥有专门适应解毒功能的肠道微生物群。因衣原体病、栖息地开发和气候变化导致种群锐减，2022年被列为濒危物种。
