Biology

Common, in places rare breeding migrant. Inhabits the flood plain forests, patches of pine forests in steppes, the grove of asiatic poplar at Zhelturanga (Ile valley), the clay ravines in deserts, the steep banks of lakes and rivers in open or hilly county in foothills. Arrives in end of April – mid-May singly or in small loose flocks of 15-30 birds, which observed at Chokpak pass in early morning. Latest migrants recorded in end of May. Breeds by separate pairs at distance at least 50-200 m apart. Nests is located in natural tree holes (willow, asiatic poplar) or in burrows depth 0.25-1.25 m excavated by birds; nest is used during several years. At the burrow’s end there is the nest chamber without any lining. Clutch of 3-7 eggs is laid in mid-May – June. Both parents excavate burrow, incubate the clutch for 18-19 days and then feed juveniles which fledge in July, at age 26-28 days old. During post-breeding dispersions birds occur in mountains much higher than breeding places, and gather on poles and wires along the roads in open country. Autumn migration begins in August; odd birds linger to the end of September – early October, latest bird recorded near Merke 29 October 2000.
