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.

Keulige Schließmundschnecke

Clausilia pumila, the clublike door snail, is a land snail in the family Clausiliidae, a group readily recognized by their sinistral (left-handed) coiling and elongated, spindle-shaped shells. C. pumila has a smooth, glossy shell approximately 12–18 mm in height, tapering to a slender apex, with fine growth lines and a distinctive clausilium—a small, spring-loaded plate inside the aperture that closes when the snail retreats. This clausilium gives the family its common name of door snails. The species is distributed across central and eastern Europe, from Germany and the Czech Republic eastward through Poland and neighboring countries, inhabiting moist deciduous forests, especially beech and mixed woodland with rich ground flora. It is typically found on limestone or calcareous substrates, living under bark, in leaf litter, on mossy rocks and rotting logs, and occasionally on living tree bark. Like other clausiliids, it is a microphytophage, rasping algae, fungi, and decaying plant material from surfaces. C. pumila is classified as Least Concern, being locally common across its range where suitable humid forest habitats persist.
