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.

Colibri à petit bec

A tiny, jewel-like high-Andean hummingbird, male purple-backed thornbills display glittering violet-purple back and rump feathers with a distinctively short bill adapted for short-tubed flowers. Found in open páramo grasslands and cloud forest edges at elevations of 2,500–4,500 meters in Venezuela, Colombia, Ecuador, and Peru. Despite their small size, they are aggressive territory defenders at flower patches. Their tiny size and high-altitude specialization make them one of the most cold-adapted hummingbirds.
