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.

Schwarzschnabel-Sturmtaucher

A medium-sized seabird of the North Atlantic and North Pacific, Manx shearwaters are renowned for their extraordinary navigation abilities. They travel up to 1 million kilometers over a lifetime, migrating annually between breeding colonies on North Atlantic islands and wintering grounds off South America. Their stiff-winged shearing flight just above wave surfaces is characteristic. One individual lived for over 55 years, one of the longest-lived wild birds recorded.
