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 à flancs blancs

A medium-sized flowerpiercer of humid Andean cloud forest and forest edges from Colombia south to Bolivia, white-sided flowerpiercers have distinctive white flank patches contrasting with dark grey-blue plumage. Like all flowerpiercers, they use their sharply hooked and slightly upturned bill to pierce the base of tubular flowers and steal nectar without pollinating — earning them the reputation as nectar thieves. Found at elevations of 1,500–3,500 meters, they are commonly encountered in Andean gardens and forest edges.
