The Turkestan House Sparrow used to be classed as a subspecies of the Indian House Sparrow, which itself
used to be classed as a separate genus, Passer indicus. Both the Indian (Passer domesticus indicus),
and the Turkestan (P. d. bactrianus) are now usually considered among the 12 subspecies of House Sparrow.
The male has the grey crown of the House Sparrow but is brighter chestnut with bright white cheeks (not grey) and an extended black bib.

It breeds in southern Kazakhstan, northern Iran and Afghanistan and winters in northern India.
The Turkestan and Indian House Sparrows are rural birds with the Tree Sparrow taking the urban niche in their regions.

Female is like the nominal House Sparrow
This may be a hybrid Common and Turkestan with grey speckled ears?
All photos above were taken by Alexandra Makhnina at an oasis in Kazakhstan where Turkestan Sparrows
were present with Common House Sparrows and the Central Asian subspecies of Spanish Sparrow. Hybrids occur.
