Validity of subspecies andersoni questionable, as its purported characters (shade of plumage, extent of breastband) are to large extent due to wear, fading and specimen preparation. Intergrades said to occur where it overlaps with nominate in southern China (northern and south-eastern Yunnan).
The following 2 subspecies are recognised:
andersoni (Swinhoe, 1870) - Central and southern China (south-eastern Gansu, Sichuan and northern Yunnan east to southern Jiangsu, Zhejiang, Jiangxi and Fujian, south to northern Guangdong).
