Simla–Almora district, Himalayas.
Hitherto treated as conspecific with G. glandarius and G. leucotis; differs from latter in characters given under that species (see below). Differs from former in its plain crown (no black streaks with white, or all black) (3); blue-and-black barred area of middle of secondaries vs white (3); pinkish-tinged buffy-rufous underparts without heavy tinge of grey (2); and whining call with repeated short notes at a pace higher than in either G. glandarius or G. leucotis (3)#R; but see latter species for note on race oatesi. Other forms have been described, most referable to intermediate populations, and best treated as synonyms: thus, insularis included in taivanus; persaturatus and azureitinctus in interstinctus; and rufescens, rubrosus and minhoensis in sinensis. Six subspecies recognized.
