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。

桂胸蜂虎

The cinnamon-chested bee-eater (Merops oreobates) is a colorful, aerial insectivore in the family Meropidae, endemic to the highlands of East Africa. It is found in Uganda, Kenya, Tanzania, Rwanda, Burundi, and eastern DRC, typically at elevations between 1,500 and 3,000 meters in montane forest edge, woodland clearings, and cultivated areas with tall trees. Like all bee-eaters, it is a masterful aerial hunter, catching bees, wasps, and other flying insects in fast pursuit flights from open perches. The plumage is brilliant—green upperparts, a bright blue rump and undertail, a distinctive cinnamon-rufous chest, and a black gorget separating the throat from the breast. The species is classified as Least Concern by the IUCN, with stable populations across the East African highlands. It often nests colonially, digging burrows into earthen banks or flat ground. The cinnamon-chested bee-eater is absent from Europe; Norwegian database records are data entry errors. This bee-eater is a popular species with birdwatchers visiting the East African highlands, often observed conspicuously from perches at forest edges. Conservation of highland forest and woodland habitats, and the retention of earthen banks for nesting, are beneficial for this species.
