Subspecies
Often treated as conspecific with Long-tailed Tit (Aegithalos caudatus), but plumage is distinctive, and there are no reports of regular intergradation or hybridization with that species in north-eastern China (apparent "intergrades" recorded as migrants in coastal Hebei, but origin and status of these unknown).
The following 2 subspecies are recognised:
vinaceus (Verreaux, J, 1871) - Central and north-eastern China from eastern Qinghai and central Gansu east to central and south-eastern Nei Mongol, southern Liaoning, northern Hebei and Shandong, and, in west, south to mountains of central Sichuan and north-western Yunnan.
glaucogularis (Moore, F, 1855) - East-central China in Yangtze valley from Hubei (possibly also lowlands of Sichuan), parts of southern Shaanxi and Henan east to Jiangsu and northern Zhejiang.
