横斑鹦哥

横纹小鹦鹉（Bolborhynchus lineola）是新大陆鹦鹉中体型最小的种类之一，栖息于从墨西哥南部至厄瓜多尔西部的中南美洲海拔1200至3000米的湿润山地森林。其绿色底色上特有的黑色横纹羽毛提供了出色的林冠伪装。常结成小群觅食种子和浆果，尤其偏爱竹林。相较于其他鹦鹉较为安静低调，野外研究甚少，部分鸟类爱好者有饲养记录。

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。
