Habitat & Geographic Range

Schleiereule

Habitat

Typically found in diverse ecosystems where prey species are available.

Range

Widely distributed across Africa (Seychelles), Europe (6 countries), North America (United States), and South America (Colombia, Ecuador, Venezuela). Population trends indicate a declining trajectory in parts of its 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.

Schleiereule

The most widespread owl species on Earth, barn owls are found on every continent except Antarctica and in almost every habitat type from tropical forests to temperate farmland. Characterized by their heart-shaped facial disc that funnels sound to asymmetrically placed ears, enabling them to locate prey in total darkness by sound alone. They swallow prey whole and regurgitate compressed pellets of indigestible bone and fur, making them valuable rodent control agents for agriculture.

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.
