Abstract
Siblicide was observed in the Black Chested Buzzard Eagle. Aggression between nest mates was seen in three out of five nests in study. Two nestlings from two of these nests died within the first ten days of hatching (one was found dead at the base of the nesting cliff). A third nest also suffered early brood reduction probably due to this phenomenon. In the study area the species seems to behave as a facultative cainist.
