Grey Eagle-buzzard
Abstract
We reviewed and summarized the literature concerning the natural history of the Grey Eagle-buzzard Geranoaetus melanoleucus. We supplement this information with our own field records from three sites along Chile. They are the Chinchilla National Reserve (300 km north of Santiago), San Carlos de Apoquindo (20 km east of Santiago), and Torres del Paine National Park (350 km north of Punta Arenas). We covered in detail the following topics: distribution and taxonomy, color and field identification, morphometry and weight, life history and reproduction, habitat use, diet, activity, flight modes and hunting behaviour, aggression, vocalizations, abundance, mortality, and other topics. With this review we update the current knowledge of the biology of the Grey Eagle-buzzard, and render more accessible the information documented in journals and books of local circulation to the interested scientific community.
