Harpy eagles are the Americas largest raptors, facing deforestation, persecution, and slow reproduction making population recovery difficult.
Slow reproduction means loss of breeding adults has long-term population impacts. Adults shot near nests leave dependent chicks to starve. Persecution involves shooting, trapping, and poisoning. Captive individuals require enormous territories equivalent to their wild range; captivity causes pacing and stereotypic behaviors. Nest tree felling during logging causes egg and chick mortality.
