Sakers occupy stick nests in trees, about 15 to 20 meters above the ground, in parklands and open forests at the edge of the tree line. No one has ever observed a saker falcon building its own stick nest; they generally occupy abandoned nests of other bird species, and sometimes even drive owners from an occupied nest. In the more rugged areas of their range, sakers have been known to use nests on cliff ledges, about 8 to 50 meters above the base.
