Barn Owl

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.

Leatherback Sea Turtle

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 5 distinct biome types spanning the Australasia and Indomalayan and Neotropic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Costa Rica, Indonesia, Malaysia, and Trinidad and Tobago. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Barn Owl

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.

Leatherback Sea Turtle

The leatherback is the largest living turtle and the fourth-heaviest reptile. Unlike other turtles, it has a soft, leathery shell.
