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.

Eisbär

Habitat

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.

Range

Found in Norway. 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.

Eisbär

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
