Habitat & Geographic Range

American Bald Eagle

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and flooded grasslands and savannas, among 10 distinct biome types spanning the Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Europe (8 countries), North America (United States), and South America (Ecuador).

Common Dwarf Bonneted Bat

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Range

Found in Venezuela.

American Bald Eagle

The national bird of the United States and a symbol of American conservation success, bald eagles have a wingspan of up to 2.4 meters and inhabit forests and wetlands near open water across North America. Powerful aerial predators and scavengers, they specialize in fish but also take waterfowl and carrion. Nearly extinct by the 1960s due to DDT poisoning and hunting, the bald eagle recovered dramatically following pesticide bans and the Endangered Species Act.

Common Dwarf Bonneted Bat

<em>Eumops bonariensis</em>, the common dwarf bonneted bat, is a small molossid bat classified as Least Concern on the IUCN Red List, suggesting its populations are currently not under significant threat. The species has been recorded in Venezuela and is associated with diverse terrestrial and aquatic habitats, reflecting the broad ecological tolerance typical of many molossid bats. <em>Eumops bonariensis</em> belongs to the free-tailed bat family Molossidae and is characterized by its distinctive bonnet-shaped ears that extend over the forehead. Like other members of its genus, this species is adapted for fast, high-altitude flight and typically forages for flying insects in open airspace above forest canopies, wetlands, and urban areas. Molossid bats are known for their echolocation calls, which they use to detect and pursue prey during nocturnal foraging bouts. The species typically roosts in tree cavities, rock crevices, or man-made structures, forming small to moderate-sized colonies. Its insectivorous habits make it an important regulator of insect populations in tropical and subtropical ecosystems. Biological traits of this species remain poorly documented in the scientific literature.
