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.

Chocolate Boobook

Habitat

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

Range

Found in Norway. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

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.

Chocolate Boobook

The Chocolate Boobook (Ninox randi) is a small to medium-sized owl in the family Strigidae, belonging to the diverse Australasian genus Ninox — the hawk-owls — which ranges from South Asia through Southeast Asia to Australia and the Pacific. This species is endemic to the Philippine archipelago, where it is found on the islands of Mindanao, Basilan, Leyte, Samar, and several adjacent smaller islands. As its name suggests, it is distinguished by its rich, warm brown plumage overall, with spotted or streaked underparts. The chocolate boobook inhabits lowland and foothill forest, including primary and mature secondary growth, where it forages nocturnally for large invertebrates, small vertebrates, and possibly small birds. Like other Ninox owls, it produces characteristic hooting or barking calls audible at night in its forest habitat. The IUCN classifies the Chocolate Boobook as Near Threatened, reflecting ongoing deforestation and habitat degradation across the Philippine lowlands, where forest has been extensively cleared for agriculture and logging over the past century. The Philippines is a global biodiversity hotspot with high endemism and severe ongoing habitat loss, making many forest-dependent species including this owl vulnerable to further population decline if conservation measures are not strengthened.
