The management of wild populations of birds of prey as a tool for their conservation is becoming increasingly widespread (Ivanovski 2000, Negro et al. 2007, Björklund et al. 2013). Specifically, the manipulation of nests and/or nestlings has proved to be a useful way for enhancing reproductive success of several raptor species (Dunstan and Borth 1970, Bohm 1977, Ivanovski 2000, Kuniy et al. 2015). This has been possible, in part, because some raptor species tolerate some level of human intervention/disturbance during the breeding season (Bird et al. 1985). For species of conservation concern, these interventions may become critical for increasing their populations in the wild (Negro et al. 2007).
The Chaco Eagle (Buteogallus coronatus) is one of the rarest and most threatened raptors in the Neotropical region (Sarasola et al. 2018, 2021), and...
