Pygargue à tête blanche

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.

Alouette hausse-col

The most widely distributed lark species, common horned larks — also called shore larks in Europe — inhabit bare, open ground from Arctic tundra and alpine fellfield to coastal beaches and prairie across North America, Europe, Asia, and North Africa. Named for the small black feather tufts on the male's head. They are among the first birds to arrive at breeding grounds in early spring while snow still covers the tundra. They forage on seeds and insects on the ground year-round.
