Closest relatives uncertain, although song rather similar to those of C. discolor and C. manipurensis. Despite this species’ occurrence in two disjunct populations, geographical variation is clinal across whole range, W birds being palest with longer bill and E birds darker and shorter-billed (cline is apparently reversed at extreme E parts of range), and molecular variation is low#R. Pronounced local individual variation tends to mask geographical variation; proposed races infima (described from W Nepal) and limes (Gilgit, Pakistan) included in nominate. Four subspecies recognized.

Subspecies and Distribution
  • C. h. taeniura Severtsov, 1873 – mountains of C Asia in E Uzbekistan, Kyrgyzstan, extreme SE Turkmenistan, Tajikistan and N Afghanistan. Probably extreme S Kazakhstan#R and extreme W Xinjiang#R (China).
  • C. h. himalayana Vigors, 1832 – E Afghanistan (S of Hindu Kush, from Nuristan S to Kandahar), N Pakistan (S at least to C Baluchistan, also in Murree Hills) and E in Himalayas (also N of main range, in upper Indus and associated valleys) to W Nepal.
  • C. h. yunnanensis Sharpe, 1902 – S China (from SW Gansu and S Shaanxi S to SE Xizang and NW & W Yunnan, also SW Guizhou) and N & NE Myanmar.
