Habitat & Geographic Range

blue whale

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. 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.

Colorful Puffleg

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 5 distinct biome types spanning the Neotropic and Oceanian realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Colombia and Norway. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

blue whale

The largest animal ever known to have lived on Earth, blue whales can reach 33 meters and 200 tonnes — their hearts alone weigh as much as a small car. Found in all oceans, they migrate between polar feeding grounds and tropical breeding areas. Filter feeders consuming up to 4 tonnes of krill daily. Endangered, with global populations estimated at 10,000–25,000 after near-extinction from 20th-century whaling.

Colorful Puffleg

<em>Eriocnemis mirabilis</em>, the colorful puffleg, is a hummingbird in the family Trochilidae assessed as Critically Endangered by the IUCN. It is one of the most threatened hummingbirds in the world, known from an extremely restricted range centred on the Pacific slope of the western Andes in Colombia, with additional records attributed to Norway likely reflecting data artefacts or taxonomic uncertainties. The species inhabits tropical and subtropical moist broadleaf forests and related cloud forest biome types between approximately 1,800 and 2,200 metres elevation. Male colorful pufflegs are distinguished by brilliant iridescent plumage and distinctive white leg puffs, features typical of the genus <em>Eriocnemis</em>. The Critically Endangered status reflects ongoing destruction of cloud forest within its tiny known range, which may encompass fewer than 100 square kilometres of suitable habitat. As a nectarivore and incidental insectivore, this hummingbird depends on intact forest for flowering plant resources and arthropod prey. Conservation of the remaining forest patches in its restricted Colombian range is considered critical for the survival of this species. Biological traits of this species remain poorly documented in the scientific literature.
