紅石燕

美洲崖燕（Petrochelidon pyrrhonota）在IUCN红色名录中被评估为无危（LC），在北美洲广泛繁殖，以集群在悬崖面和建筑物上筑泥质壶状巢为独特行为。该物种是著名的长距离迁徙鸟类，每年往返于北美繁殖地和南美洲越冬地之间。其高超的飞行技巧和集群繁殖策略是对开阔生境的完美适应。

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。
