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 Spiny Digger Wasp

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 Spiny Digger Wasp

<em>Oxybelus uniglumis</em>, commonly known as the common spiny digger wasp, is a small solitary wasp in the family Crabronidae, widespread across Europe, North Africa, and parts of western Asia. This species typically inhabits sunny, open areas with sandy or loose soil, including sand dunes, sandy heathlands, path edges, and sparsely vegetated ground where females excavate burrows for nesting. Its geographic range extends from the British Isles and Scandinavia across continental Europe to the Mediterranean, with additional populations recorded across North Africa and into central Asia. Classified as Least Concern on the IUCN Red List, <em>Oxybelus uniglumis</em> is among the more commonly encountered digger wasps in European sandy habitats. The species is a specialised predator of flies, particularly small dipterans from families such as Muscidae and Calliphoridae, which are paralysed and carried back to the burrow impaled on the female's sting to provision larval cells. This behaviour of impaling prey on the sting for transport is a distinctive characteristic of the genus Oxybelus. Biological traits such as average lifespan in years, precise body length measurements, and body weight remain poorly documented for this species. Adults are typically active from late spring through late summer.
