Habitat & Geographic Range
Batará Cinéreo
Typically found in various aerial, terrestrial, and aquatic environments.
Distributed across Colombia, Ecuador, Norway, and Venezuela.
Oso Polar
Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.
Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.
Batará Cinéreo
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.
Oso Polar
El mayor carnivoro terrestre de la Tierra, el oso polar puede superar los 700 kg y se encuentra en el hielo marino del Artico, desde Canada hasta Rusia. Es un mamifero marino altamente especializado que depende del hielo marino para cazar focas anilladas y barbadas. Excelente nadador capaz de cubrir grandes distancias en agua abierta. Clasificado como Vulnerable, sus poblaciones soportan una presion severa por la rapida perdida de hielo marino artico debida al cambio climatico.
