Habitat & Geographic Range

Buckelwal

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 (5 countries), and South America (Colombia, Ecuador, Venezuela). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Cloud-forest Screech-Owl

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.

Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

Cloud-forest Screech-Owl

The cloud forest screech-owl (Megascops marshalli) is a small owl in the family Strigidae endemic to the eastern slopes of the Andes in Peru and Bolivia, inhabiting cloud forest and humid montane woodland between approximately 900 and 2,200 meters elevation. Described scientifically in 1981, it belongs to the diverse Megascops screech-owl assemblage of the Americas. The species has brown, streaked cryptic plumage and small ear tufts typical of screech-owls, with a characteristic song used for territory advertisement in cloud forest habitats. It is nocturnal and insectivorous, feeding on large insects, small lizards, and other invertebrates caught in the forest understory. The cloud forest screech-owl has a restricted range on the humid eastern Andean slopes, where increasing deforestation for agriculture and coca cultivation reduces suitable habitat. Its population status is considered Least Concern given the continuing extent of Andean cloud forest in its range, though forest clearance on the eastern Andean slopes remains a long-term threat to this and many other narrowly endemic cloud forest bird species.
