Hab. Kansu, the Upper Chuanche, and southern Koko-nor mountains.
It inhabits woods both deciduous and conifer in the moun¬tains, bushes in the alpine districts, and juniper thickets in the lower alpine region, occurring up to an altitude of 12,000 feet. In spring and autumn it is seldom seen in pairs but in flocks of three to ten individuals. Fledged young were seen in July and family parties in August. In habits it resembling Turdus gouldi, and is an equally good songster ; its song resembles that of the Song Thrush. Its call note resembles the syllables tschok, tschok, tschok. Two nests taken by Prjevalsky in the Southern Koko-nor Mountains on the 26th of May, contained 8 and 4 fresh eggs, and were placed in rocks under a protruding stone, one about seven and the other about four¬teen feet above the dry bed of a stream, and placed where they were easily seen. One was built entirely of grass-bents and the other of grass-bents lined with hair, and feathers of Perdix sifanica. The eggs resembled those of the Fieldfare but several were so closely spotted that the ground colour was scarcely visible. In size they varied from 33 by 23 to 31.6 by 22.25 millimetres (1.30 by 0.91 to 1.23 by 0.88 inch). Both male and female took their share in incubating.
