Abstract

During the summer of 2002, I observed a direct aggressive contact between a White-throated Hawk and a Red-backed Hawk in central-south Chile. Each of the hawks in flight grappled its talons with the other, and pushed its feet against its opponent, rotating briefly downward in cartwheels. Afterwards, the birds broke free of each others talons. No injury or loss of aerodynamic control was apparent. This type of antagonistic display, utilized presumably as territorial defense, would be the first reported for Falconiforms in Chile.
