The eleven subspecies from the cinereous tit had been the moment lumped with The nice tit but modern genetic and bioacoustic studies now independent that group as a distinct species The good tit was previously handled as starting from Britain to Japan and south on the islands of Indonesia, with 36 explained subspecies ascribed to 4 principal species groups. The major group had 13 subspecies across Europe, temperate Asia and north Africa, the small team's 9 subspecies occurred from southeast Russia and Japan into northern southeast Asia and also the 11 subspecies within the cinereus team were being observed from Iran across south Asia to Indonesia.
