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 Antshrike

Habitat

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

Range

Distributed across Colombia, Ecuador, Norway, and Venezuela.

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 Antshrike

The cinereous antshrike (Thamnomanes caesius) is a small, insectivorous bird in the family Thamnophilidae, found across Amazonia and the Orinoco basin in South America. It ranges from Venezuela, Colombia, and the Guianas south through Brazil to Bolivia and Peru. This species is a characteristic member of Amazonian mixed-species foraging flocks, in which it serves as a sentinel, alerting other species to approaching predators while also flushing insects for other flock members. It inhabits the undergrowth and lower to mid strata of terra firme and humid forest, particularly avoiding seasonally flooded várzea. The male is largely gray-blue with a black throat, while the female is brownish with a rufous wash. The cinereous antshrike is classified as Least Concern by the IUCN, with a vast Amazonian range and stable populations in intact forest. As a nuclear species in mixed-species flocks, its presence or absence has cascading effects on the diversity and composition of the flocking community. Deforestation of Amazonian terra firme forest poses the primary long-term threat to this and many co-occurring antbird species. The species is entirely absent from Europe; any database record listing Norway as its range is an artifact of data entry error.
