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 Purple & Gold

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 Purple & Gold

The Common Purple and Gold, <em>Pyrausta purpuralis</em>, is a small moth in the family Crambidae, subfamily Pyraustinae, found across northern and western Europe including Belgium, Denmark, Norway, and Sweden. It is a distinctively patterned species with rich purple-crimson forewings marked by bright golden-yellow spots and patches, making it one of the more visually striking micro-moths of the European fauna. The species typically inhabits calcareous grasslands, chalk downs, coastal cliffs, and heathlands where its larval host plants, particularly species of wild thyme (<em>Thymus</em>) and marjoram (<em>Origanum</em>), are abundant. The caterpillars typically feed on the leaves and stems of these aromatic herbs in sheltered, sun-exposed sites. Adults fly in one or two generations per year, typically from late spring through summer, and are diurnal, often seen nectaring on flowers in warm sunshine. <em>Pyrausta purpuralis</em> is assessed as Least Concern on the IUCN Red List given its distribution across suitable habitats in Europe. Biological traits such as average lifespan, body size, and specific dietary preferences remain poorly documented for this species.
