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.

Percefleur de Lafresnaye

A medium-sized flowerpiercer with glossy, iridescent blue-black plumage that catches light with a deep metallic sheen, glossy flowerpiercers use their specialized hooked bill to pierce flower bases and rob nectar without effecting pollination — a form of nectar theft that has evolved independently multiple times in birds. Found in humid Andean cloud forest and forest edges from Colombia to Bolivia at elevations of 1,500–3,500 meters. Common in forest edges and gardens with abundant tubular-flowered plants.
