黑白食籽雀

黑白食籽雀（Sporophila luctuosa）是一种小型、花纹鲜明的食籽雀，雄鸟具有醒目的黑白羽色——纯黑的上体和翅膀与白色的下体形成强烈对比——栖息于从哥伦比亚至玻利维亚安第斯山脉的草地、林缘和种植园遮阴处等开放和半开放生境。是花纹最鲜明的Sporophila食籽雀之一。雌鸟为朴素的棕色和黄褐色。以草籽为食，雄鸟因其花纹和鸣声有时被作为笼鸟饲养。

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。
