First report of the nesting of the Chilean Hawk (Accipiter chilensis) in Argentina

Abstract

We describe the first documented nest of the Chilean Hawk (Accipiter chilensis) in Argentina, and give details on the nesting behaviour of parents and nestlings during the fledging stage of the nesting cycle. The nest was found in a coihue (Nothofagus dombeyi) forest in the Nahuel Huapi National Park, Río Negro Province, Argentina. The nest structure was a platform of sticks built 25.3 m in the canopy of a coihue tree. On three visits to the nest between January and February 2004, we observed adults bringing avian prey items to the nestlings in the nest.
