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.

Petit-duc de Colombie

<em>Megascops colombianus</em>, commonly known as the Colombian screech-owl, is a small nocturnal raptor native to the Andean foothills of Colombia and Ecuador. This species inhabits tropical and subtropical montane forests, where it occupies a range of elevations typically between 1,000 and 2,000 metres above sea level. The Colombian screech-owl is assessed as Near Threatened by the IUCN, reflecting ongoing habitat loss driven by agricultural expansion and deforestation within its restricted range. Like other members of the genus <em>Megascops</em>, this owl is presumed to be an insectivore and opportunistic predator of small vertebrates, hunting under cover of darkness using acute hearing and silent flight. Its cryptic plumage provides effective camouflage against tree bark, making individuals difficult to detect. The species is poorly known, with limited published data on its breeding biology, population size, and precise ecological requirements. Research indicates that ongoing forest fragmentation in the Colombian Andes represents the primary threat to long-term population viability. Biological traits of this species remain poorly documented in the scientific literature.
