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.

Blaugrüner Zärtling

Entoloma querquedula is an agaric fungus in the family Entolomataceae, assessed as Near Threatened (NT). It is found in nutrient-poor, unfertilised grassland and mire habitats that have declined due to agricultural intensification and drainage. Its near-threatened status reflects sensitivity to grassland management changes.
