Black-chested Buzzard-Eagle Geranoaetus melanoleucus
Version: 1.0 — Published February 8, 2013
Behavior
Introduction
Black-chested Buzzard-Eagles forage in soaring flight.
Territoriality
Black-chested Buzzard-Eagle generally is aggressive towards other species and conspecifics, with aggressive encounters taking up nearly 2% of the eagle’s time (Jaksic and Jimenez, 1989). Both male and female individuals will actively guard the nest from approaching birds during the breeding season (Salvador Jr. et al 2008).
Sexual Behavior
No concrete information of the mating system of this species. While the buzzard eagles make pairs during the breeding season, it is unknown how strict this relationship is and if it exists outside of the breeding season (Jimenez and Jaksic 1989). Jimenez and Jaksic believe that these pairs do not dissolve when the breeding season ends.
No information on extra-pair copulations.
Social and interspecific behavior
Black-chested Buzzard-Eagle usually is solitary. This species may have pair bonds that outlast the breeding season, but individuals are often solitary when not in pairs or with offspring (Jimenez and Jaksic 1989).
Nesting eagles often are pestered by American Kestrels Falco sparverius (Salvador Jr. et al 2008). Variable (Geranoaetus polyosoma) and Harris's (Parabuteo unicinctus) hawks show aggression towards Black-chested Buzzard-Eagles outside of the breeding season (Jaksic and Jimenez 1986).
