The Grey Falcon Falco hypoleucos: A Summary of Information

Abstract

Historical and recent literature data on the Grey Falcon Falco hypoleucos are assembled and supplemented by field observations. Data on field characters, physique, diet, hunting behaviour, displays and breeding biology are reviewed and compared with other Falco species. It is concluded that in physique and feeding ecology, including its ability to take many fast-flying birds, the Grey Falcon has much in common with the Barbary Falcon Falco pelegrinoides and other desert falcons such as the Lanner Falcon Falco biarmicus. In breeding biology, including the lack of hard evidence on its alleged nest-building habit, the Grey Falcon resembles the larger falcons.
