Raptors play a key role as top-down modulators in the ecosystem. Larger eagles and owls can have important effects on mesopredator populations through intraguild predation, as well as through competition for resources. In addition, these larger predators are often perceived as dangerous for domestic animals and game species, and are therefore frequently persecuted in the context of conflict with humans. Identifying potential conflicts is therefore critical in order to prevent them and to design conservation measures to solve them. The Black-and-chestnut Eagle (Spizaetus isidori) is a large eagle that inhabits subtropical or tropical montane cloud forests of the Andes slopes up to 3000 masl. Throughout its range, this species occupies relatively narrow habitats from northwestern Venezuela and northeastern Colombia extending through the center of Ecuador, Peru, and Boliviato northwestern Argentina.
