灰背舞雀

灰盐鸟是一种中大型健壮的鸟类，上体灰色，下体近白，具有被黑色髭纹镶边的醒目白喉，栖息于从墨西哥经中美洲至玻利维亚和阿根廷的广大分布区内的林缘、庭园和次生林地。适应性极强，在热带拉丁美洲各地的城郊公园和庭园中均能茁壮生长。它们发出丰富多变的悦耳鸣声，是受干扰的新热带景观中较为常见的大型鸣禽之一。

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。
