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).

Coastal Leaf-Cutter Bee

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, and Luxembourg. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

Coastal Leaf-Cutter Bee

Megachile maritima, the coastal leaf-cutter bee, is a solitary bee in the family Megachilidae that constructs nests from leaf pieces cut from plants using its mandibles, a behaviour characteristic of the entire genus. The species is native to western and northern Europe, with confirmed populations in Belgium, Denmark, and Luxembourg, inhabiting coastal sand dunes, sandy grassland, and inland sandy heathland where it nests in the ground in loose, well-drained sandy soil. Female Megachile maritima cut semicircular pieces from the leaves of various plants, particularly vetches, clovers, and other legumes, to line the individual brood cells she constructs within the nest burrow. Each cell is provisioned with a pollen and nectar paste before a single egg is laid and the cell sealed with additional leaf pieces. Males emerge first and patrol vegetation in search of females. The species is classified as Vulnerable by the IUCN, reflecting substantial population declines associated with the loss of open sandy habitats through coastal development, vegetation succession and scrub encroachment on dunes, reduction of foraging plant diversity through agricultural intensification, and general declines in wild bee populations across northwestern Europe driven by pesticide use and habitat loss.
