Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

黑雞鵟

Habitat

Typically found in various aerial, terrestrial, and aquatic environments.

Range

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。

黑雞鵟

The common black hawk (<em>Buteogallus anthracinus</em>) is a medium-sized raptor of the family Accipitridae, classified as Least Concern on the IUCN Red List. It inhabits aerial, terrestrial, and aquatic environments across its range, which includes Colombia, Ecuador, Venezuela, and, notably, Norway, suggesting occasional vagrant or introduced occurrences outside its core Neotropical distribution. <em>Buteogallus anthracinus</em> is typically associated with riparian forests, mangroves, and wetland edges, where it hunts crabs, fish, frogs, and other aquatic prey along stream banks and shorelines. The bird is predominantly black with a broad white tail band, making it distinctive in the field. It often perches conspicuously on exposed branches near water, scanning for prey below. The species typically nests in tall trees near water, constructing large stick nests used across multiple breeding seasons. Biological traits of this species remain poorly documented in the scientific literature.
