Habitat & Geographic Range

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.

Uhu

Habitat

Found across multiple habitat types including tropical and subtropical dry broadleaf forests, flooded grasslands and savannas, and montane grasslands and shrublands, among 4 distinct biome types within the Neotropic biogeographic realm.

Range

Found across Europe (9 countries) and South America (Ecuador). Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

Uhu

The world's largest owl species by height and weight, Eurasian eagle-owls have wingspans up to 1.9 meters and inhabit rocky landscapes, forest edges, and cliffs from Europe across Asia to China. Silent nocturnal hunters with powerful talons, they prey on rabbits, hares, foxes, and even other raptors. Their deep, resonant hooting carries over great distances. Relatively stable in population, though persecuted historically.
