Habitat & Geographic Range

Weißkopf-Seeadler

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).

Zweizahn-Winkelspanner

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

Weißkopf-Seeadler

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.

Zweizahn-Winkelspanner

The cloaked carpet (Euphyia unangulata) is a geometrid moth in the family Geometridae found across temperate Europe and parts of western Asia. The adult wingspan typically measures 22–28 mm, with forewings displaying the characteristic carpet moth pattern of transverse bands and cross-lines in shades of grey, brown, and white, providing effective camouflage against tree bark and lichen-covered surfaces. The species inhabits deciduous woodland, scrubby hedgerows, and woodland margins where its larval foodplants, including chickweed (Stellaria species) and related low-growing herbaceous plants, are abundant. Adults fly in one or two generations per year depending on latitude, typically on the wing from late spring through late summer. Larvae feed through summer and autumn, pupating in soil or leaf litter. Like many geometrid moths, the cloaked carpet has experienced population declines across parts of its European range, attributed to loss of diverse woodland understory, reduction in traditional coppicing practices, and changes in land management that reduce the availability of shaded, moist microhabitats where foodplants thrive.
