probably west China.
Taxon harmani here considered a distinct species on account of mid-grey upperparts and underparts (except for white throat, neck-sides and mid-belly and whitish-grey rump), with white belly patch vs pale grey in morphologically closest form dolani (2); neck greyish-black, causing white throat and narrow white collar to stand out sharply (3); white belly patch vs none (1); slightly smaller size (on small sample, NHMUK, where mean wing 286 vs 310; at least 1). Intergrades among races reported, suggesting that several may be of dubious validity; drouynii found to exhibit individual variation at one site#R. Four subspecies currently recognized.
