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.

Buchen-Helmling

Mycena fagetorum is a small, delicate agaric fungus in the family Mycenaceae, assessed as Near Threatened (NT). It grows on decaying beech (Fagus) litter and woody debris in mature beech woodland habitats. Its near-threatened status reflects dependence on undisturbed beech forest ecosystems that have declined through logging and land conversion.
