Habitat & Geographic Range

Schleiertangare

Habitat

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

Range

Distributed across Colombia, Ecuador, Norway, and Venezuela.

Blauwal

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

Schleiertangare

A medium-sized tanager with a distinctive black face mask contrasting with grey-white body plumage, black-faced tanagers inhabit forest edges, secondary woodland, cerrado, and open scrub across a broad range from Colombia and Venezuela south through the Guianas and Brazil. They are adaptable birds tolerant of disturbed and degraded habitats, foraging on fruit, berries, and insects in pairs and small groups. Listed as Least Concern and among the more common tanagers in disturbed habitats across northern South America.

Blauwal

The largest animal ever known to have lived on Earth, blue whales can reach 33 meters and 200 tonnes — their hearts alone weigh as much as a small car. Found in all oceans, they migrate between polar feeding grounds and tropical breeding areas. Filter feeders consuming up to 4 tonnes of krill daily. Endangered, with global populations estimated at 10,000–25,000 after near-extinction from 20th-century whaling.
