Distribution

Breeds in east-central China (south-eastern Gansu, south-western Shaanxi, northern Sichuan and northern Yunnan). A recent paper describes then as possibly more numerous than previously recognized, finding them on the southern slopes of the Qinling Mountains
Non-breeding grounds uncertain. Has been recorded in winter in northern Thailand and southern China.
A restricted-range species with only few recent records. Most probably declining due logging and conversion of forest to farmland.
