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.

Tangara à cape bleue

A brilliantly colored Andean tanager with deep purplish-blue mantle and chestnut flanks contrasting with black face and wings, purplish-mantled tanagers inhabit humid cloud forest and forest edges at elevations of 1,000–2,200 meters in Colombia and Ecuador. Males display strikingly iridescent purple mantle plumage that shimmers in canopy light. They inhabit forest interior and edge in pairs and small groups, foraging on fruit and insects. Listed as Vulnerable due to significant deforestation of Colombian and Ecuadorian cloud forest.
