.

Geographical variation in main part of range rather moderate, and probably clinal, palest populations occurring in far N areas. Isolated S population castaneiceps more distinctive, and may represent a separate species, having darker crown and nape (rufous-chestnut vs rufous) (1), rather more extensive black on lores, sometimes extending above eye in short supercilium (ns[1]), whitish vs metallic royal-blue moustachial patch (2), greatly reduced blue on (and more attenuated) black rear ear-coverts (2), but apparently no mensural or vocal differences. Four subspecies currently recognized.
