Migrates singly, the latest birds observed at Chokpak Pass in early May, in Kyzylkum desert one bird shot in May 26. Breeds in separate pairs, at least 750 m, usually several kilometers apart. Nest is built on ground under the bush or grass tussock; from the dry twigs and is lined with grass. The birds of subspecies F.c.pallidus nest in old Crows nests in bushes, trees at 3-6 m above ground. Living in mountains birds of subspecies F.c.lymani nest mostly in the old Crows or Magpies nests, in trees and bushes, often at 10-15 m above the ground.
