It is found in the mountains of eastern Turkey, Armenia, Azerbaijan and throughout the Alborz Mountains of Northern Iran. It breeds at altitudes from 1,800–3,000 m (5,900–9,800 ft) on bare stony ground with some alpine scrub. It nests in a bare ground scrape and lays 6–9 greenish eggs, which are incubated only by the female. Its diet consists of seeds and vegetable matter. It forms small flocks when not breeding.

Description

This snowcock ranges from 56 to 63 cm (22 to 25 in) in length, 95 to 105 cm (37 to 41 in) in wingspan and 1.8 to 2.9 kg (4.0 to 6.4 lb) in weight.[2] Its plumage is patterned with grey, brown, white and black, but this snowcock looks pale gray from any distance. The breast is pale gray, the throat and a white patch on the side of the neck are white, and the nape is dark gray.

In flight, this wary bird shows white flight feathers and undertail. Male and female plumages are similar, but juveniles are slightly smaller and duller in appearance. There are three races differing in plumage saturation, becoming paler from west to east.

The Caspian snowcock has a desolate whistling song, vaguely like a Eurasian curlew, sooo-looo-leeee. It differs from Caucasian snowcock in that it does not have the drop in pitch at the end of the song shown by that species. The calls include loud cackles and bubbled buck-buck-buck-buck-burrrrrr.
