Typically found in open habitats of desert, grasslands, meadows and agricultural fields, it is most often seen sitting on top of a tall telephone pole or an isolated tree. This large falcon hunts mainly for small mammals and small to medium-sized birds, but it will also take reptiles and large grasshoppers. It forages by flying over the prey and stooping down on them and also by diving from its high isolated perch. The nest is located on a high cliff ledge or rock crevice over open habitat.
The four-digit banding code is PRFA.
