The Rufous-tailed Rock Thrush is common, in places rare breeding migrant. It is typical mountain bird. It inhabits the mountains when the rock, the clay precipices or the open places alternate with the bushes or tree groups on 500-600 till 2500-3500 m (in West Tien Shan); but in the sub-alpine and the alpine belts its number is very low. On migration it visits the steppes and desert plains with the broken lay of the ground. It appears in early-mid April singly or in small groups, in highlands in early-mid May only. Last migrants recorded in Kolshengel (Southern Trans-Balkhash area) on mid-May. It breeds in separate pairs not close one to another. The female builds nest in the cavity or in the rock cracks, between the stones, or on ground under stone; nest is built from the moss, the dry grass and rootlets and is lined with same but thinner materials. Clutch of 4-6 (usually 5) blue eggs founds on mid-May - mid-June. Both parents feed juveniles fledged in mid-June - late July. It eats the different insects and in autumn also the berries and fruits. The autumn migration is in August, latest birds recorded in mid-September.
