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.

Cinereous Bulbul

Habitat

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

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.

Cinereous Bulbul

The cinereous bulbul (Hemixos cinereus) is a medium-sized songbird in the family Pycnonotidae, found across Southeast Asia, including Thailand, Malaysia, Sumatra, and Borneo. It inhabits montane and hill forest, typically at elevations between 600 and 2,000 meters, where it forages for fruits, berries, and insects in the forest canopy and sub-canopy. The species is characterized by its gray-brown plumage, slightly crested head, whitish throat, and pale underparts that distinguish it from related bulbuls. It is often encountered in small groups or mixed-species foraging flocks in upland forest. The cinereous bulbul is classified as Least Concern by the IUCN, with stable populations across a moderately large range in the highland forests of the Malay Peninsula and the large islands of Sundaland. Its montane forest habitat makes it less susceptible to lowland deforestation than many related species, though continued conversion of hill forest for plantation agriculture at mid-elevations could affect populations. The genus Hemixos includes only a few species found across South and Southeast Asia, all associated with montane forest habitats. The cinereous bulbul is occasionally observed by birdwatchers visiting highland sites such as Fraser's Hill in Malaysia and Doi Inthanon in Thailand.
