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.

Streaked Saltator

Habitat

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

Range

Distributed across Colombia, Ecuador, Norway, and Venezuela.

blue whale

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.

Streaked Saltator

A medium-sized saltator of Pacific coastal lowlands in Colombia, Ecuador, and Panama, streaked saltators are named for the heavy brown and white streaking across their breast and flanks. They inhabit forest edges, thickets, and secondary woodland, foraging on seeds and fruit in pairs and small groups. Listed as Least Concern but with a restricted range in Pacific lowland habitats increasingly threatened by agricultural expansion and deforestation. They produce characteristic rich whistled notes typical of saltators.
