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 Awl-fly

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

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 Awl-fly

<em>Xylophagus ater</em>, commonly known as the Common Awl Fly, is a dipteran insect in the family Xylophagidae. This species is assessed as Least Concern on the IUCN Red List and is distributed across parts of northern and western Europe, with records from Belgium, Denmark, Norway, and Sweden. The larvae of Common Awl Flies are typically found in decaying wood and moist, rotting logs, where they develop as predators of other wood-inhabiting invertebrate larvae. This saproxylic association makes the species dependent on the availability of large-diameter deadwood in forest habitats. Adults are slender, dark flies resembling small robber flies, and they are typically encountered in woodland environments near their larval habitats. As saproxylic insects, Common Awl Flies play an important role in forest nutrient cycling by contributing to the decomposition of dead wood. Their presence in a habitat often indicates a relatively undisturbed forest ecosystem with sufficient deadwood resources. Biological traits of this species remain poorly documented in the scientific literature.
