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。

藍鯨

蓝鲸是地球上已知存在过的最大动物，体长可达33米，体重达200吨，其心脏单独就重达一辆小型轿车的重量。分布于各大洋，在极地觅食地和热带繁殖地之间进行迁徙。它们是滤食性动物，每日可消耗多达4吨磷虾。蓝鲸被列为濒危物种，20世纪捕鲸活动使其濒临灭绝，目前全球种群估计约为1万至2.5万头。
