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。

灰短腳鵯

The cinereous bulbul (Hemixos cinereus) is a medium-sized songbird in the family Pycnonotidae, found across Southeast Asia, including Thailand, Malaysia, Sumatra, and Borneo. It inhabits montane and hill forest, typically at elevations between 600 and 2,000 meters, where it forages for fruits, berries, and insects in the forest canopy and sub-canopy. The species is characterized by its gray-brown plumage, slightly crested head, whitish throat, and pale underparts that distinguish it from related bulbuls. It is often encountered in small groups or mixed-species foraging flocks in upland forest. The cinereous bulbul is classified as Least Concern by the IUCN, with stable populations across a moderately large range in the highland forests of the Malay Peninsula and the large islands of Sundaland. Its montane forest habitat makes it less susceptible to lowland deforestation than many related species, though continued conversion of hill forest for plantation agriculture at mid-elevations could affect populations. The genus Hemixos includes only a few species found across South and Southeast Asia, all associated with montane forest habitats. The cinereous bulbul is occasionally observed by birdwatchers visiting highland sites such as Fraser's Hill in Malaysia and Doi Inthanon in Thailand.
