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.

Höckerschwan

The most commonly encountered swan globally and one of the largest flying birds, mute swans weigh up to 15 kg and inhabit lakes, rivers, and coastal bays across Europe and Asia, with widespread introduced populations in North America and Australia.
