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.

Chowchilla

Habitat

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

Range

Found in Norway.

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.

Chowchilla

The chowchilla (Orthonyx spaldingii) is a large, ground-dwelling bird in the family Orthonychidae, endemic to the rainforests of northeastern Queensland, Australia. It inhabits the dense leaf litter of tropical upland forests, particularly in the Wet Tropics region including the Atherton Tablelands. The species is closely related to the southern logrunner but is notably larger and restricted to a higher elevation range. Chowchillas forage by vigorously raking through leaf litter with their feet, exposing insects, worms, and other invertebrates beneath. Their stiff tail feathers serve as a prop during this foraging behavior, a distinctive adaptation shared with logrunners. The species is sexually dimorphic: males display a striking white throat and breast, while females have a rufous-orange throat. Chowchillas are highly territorial and maintain year-round home ranges in pairs. Their loud, rollicking chorus calls are among the most distinctive sounds of the Queensland rainforest and are often heard at dawn. Nests are domed structures of moss and leaf material, typically constructed at the base of a tree or among dense vegetation. The species is considered stable within its restricted range and benefits from the protection afforded by the Wet Tropics World Heritage Area, though habitat loss outside protected zones remains a concern.
