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.

Cloud-forest Pygmy-Owl

Habitat

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

Range

Distributed across Colombia, Ecuador, and Norway. Currently classified as Vulnerable 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.

Cloud-forest Pygmy-Owl

Cloud forest pygmy owls are small raptors in the genus Glaucidium (family Strigidae) inhabiting the montane cloud forests of Central and South America and Southeast Asia. These diminutive owls, typically 15–20 cm in length, are adapted to the cool, misty conditions of cloud forest zones at elevations from 1,500 to above 3,000 meters. Despite their small size, they are active and aggressive diurnal and crepuscular predators, hunting birds, lizards, large insects, and small mammals in the dense undergrowth and canopy of cloud forest. Many Glaucidium species possess distinctive false eye-spots on the back of the head — ocelli — that may deter attacks from behind by larger predators. Several cloud forest pygmy owl species have restricted ranges limited to individual Andean mountain ranges or Central American highland massifs, making them vulnerable to deforestation. The destruction and fragmentation of Andean and Central American cloud forests for coffee cultivation, timber extraction, and agricultural expansion have reduced suitable habitat for several Glaucidium species that depend on structurally complex, mature cloud forest.
