Reproduction
The nesting period lasts from April to June. Nest suits in abandoned burrows of rodents, such as gophers. In the depths of the burrow, the female builds a nest of stalks, grass, fluff, hair and feathers. The male accompanies the female during the transportation of the material and guard. In the clutch there are from 4 to 7 pale blue, sometimes with reddish spots eggs of 22.8 × 17 mm. Hatching lasts 14 days. Two broods occur annually. Both parent birds are involved in feeding the chicks. Nestlings leave the burrow only when they are fully prepared to fly, however they can make short sorties to the surface and at a small age. At the slightest danger, they quickly hide back into the hole, since they very deftly run and jump, not having learned to fly yet. It is easiest to find a hole with a brood in the steppe by ear, following a characteristic squeaky shout issued by chicks waiting for their parents.
