Distribution: Indomalayan/Palearctic. Breeds in southern SIBERIA AND MONGOLIA east to northeastern CHINA and possibly NORTH KOREA south to central CHINA and southeastern TIBET; winters to northern INDIA (Kashmir to Sikkim), eastern CHINA and KOREA. more....

Subspecies: Monotypic.

Taxonomy: Forms a superspecies with B. rufinus, or perhaps best regarded as a race of that species. According to Vaurie (1965), the breeding ranges of the two forms overlap in Central Asia and Mongolia, and possible hybrids between them have been reported from the border area of Kazakstan and China (Haataja 2006) and Malaysia (Soon 2008).

Movements: Partial migrant (Bildstein and Zalles 2005).

Habitat and Habits: Breeds in steppe and desert areas generally (Brazil 2009), in forest-steppe and open hilly areas with rocky outcrops in Russia (Flint 1984), in semi-deserts, deserts, foothills and mountains in Kazakhstan (Wassink and Oreel 2007), and in fields and open areas in Tibet (Lang et al. 2007). ex. extended link: more....

Food and Feeding Behavior: Feeds on rodents, including voles, susliks, gerbils, and pikas, and occasionally small birds. In Mongolia, where most of the population breeds, the principal prey is the Brandt's Vole (Lasiopodomys brandtii), and breeding success is highly dependent on vole density (Gombobaatar et al. 2005). Sundev et al. (2009) found that nestling growth, clutch size, and fledging success are significantly correlated with vole density.

Breeding: Builds a rather small stick nest placed on a rocky cliff, stony talus slope, under bush, or even in a pile of rocks. The nest is lined with wool, rags, and dry manure. Clutch size is 3-4 white eggs with yellowish-brown spots. The incubation period is about 30 days, and the nestling period is about 45 days. more....

Conservation: Categorized globally as a species of "Least Concern" by BirdLife International.
