Abstract

The interactive behaviors among birds are usually related to foraging and competition for resources. In some cases, birds can develop aggressive behaviors, such as mobbing behavior to reduce predation risk. This behavior is more common in smaller birds, thus this short communication describes this antagonistic conduct between two raptors. Seven displays of mobbing by the Yellow-headed Caracara over the Southern Caracara were recorded in the reproductive period of 2012. In this case, this aggressive behavior could be held as a preventive action against predation of nests and newborn chicks.
