Taxonomy uncertain. Race severtzovi (with kobdensis and diabolicus) has been treated as a separate species based on differences in plumage, breeding habitat and apparently vocalizations#R#R; however, taxa appear simply to be pale forms, with more intense white spotting on crown and breast and in whitish outer vane to outermost rectrix; moreover, molecular analysis has not confirmed the split#R and limited recordings suggest no difference in calls. Birds from WC Himalayas (Chitral E to Nepal and adjacent S Tibetan Plateau) proposed as race eblis (described from Puga, in E Kashmir), purportedly larger and slightly darker red than those further W in Himalayas, but differences may be clinal; further research required, including study of variation of diabolicus and birds from NW India. Four subspecies recognized.
