Habitat & Geographic Range

Baleia jubarte

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.

Cocha Antshrike

Habitat

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

Range

Distributed across Colombia, Ecuador, and Norway. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Baleia jubarte

Entre as baleias grandes mais acrobáticas, as baleias-jubarte são famosas por seus cantos complexos e evocativos entoados pelos machos durante a temporada reprodutiva, podendo durar horas e evoluir ao longo do tempo. Atingindo 16 metros e 30 toneladas, realizam as migrações mais longas de qualquer mamífero. Encontradas em todos os oceanos, alimentam-se de krill e peixes pequenos usando a técnica cooperativa de rede de bolhas.

Cocha Antshrike

The cocha antshrike (Thamnophilus praecox) is a poorly known, range-restricted bird in the family Thamnophilidae—the antbirds—endemic to a narrow strip of floodplain forest along the lower Napo River drainage in northeastern Ecuador and immediately adjacent northern Peru. The species is strongly associated with dense, shrubby vegetation in seasonally or permanently flooded várzea and igapó forests, particularly thickets of Gynerium sugarcane and other tall grasses and shrubs at the forest-water interface in oxbow lakes and riverine backwaters—habitats reflected in its name, 'cocha' being a Quechua word for lagoon or lake. Males display the typical antshrike pattern of bold black and white barring on the wings and mantle, with a black crown and white underparts; females are rufous-brown above with streaked underparts, providing camouflage in dense vegetation. The cocha antshrike feeds by gleaning insects and other arthropods from low vegetation within its flooded forest thickets, foraging in pairs or small groups year-round within apparently stable territories. Its highly specialized and fragmented habitat makes the species particularly vulnerable to deforestation, petroleum extraction activities, and hydrological alteration of Amazonian floodplain systems. Classified as Near Threatened by the IUCN, the cocha antshrike faces ongoing threats from habitat loss within its extremely restricted range, and comprehensive population surveys remain a research priority.
