Subspecies
Until recently present genus normally subsumed into a broad Parus, and many authors still prefer that treatment. Genus normally treated as feminine, but no evidence in original description or elsewhere justifies this, so genus is masculine by default. Forms a superspecies with Boreal Chickadee (Poecile hudsonicus) and Chestnut-backed Chickadee (Poecile rufescens), and all have sometimes been treated as conspecific. Regularly hybridizes with Willow Tit (Poecile montanus). Subspecies intergrade, and boundaries between them poorly defined. The ranges listed are provisional.
The following 4 subspecies are recognised:
lapponicus (Lundahl, 1848) - Fennoscandia (except south) and northern European Russia.
cinctus (Boddaert, 1783) - North-eastern European Russia and Siberia east to Bering Sea and Kamchatka, south to L Baikal and north-central Mongolia.
sayanus Sushkin, 1904 - Southern Siberia (Altai east to southern Baikal area) and north-western Mongolia.
lathami (Stephens, 1817) - North-western USA (western and northern Alaska) and north-western Canada.
