Taxonomic note
The BirdLife Taxonomic Working Group is aware that phylogenetic analyses have been published which have proposed generic rearrangements which may affect this species, but prefers to wait until work by other taxonomists reveals how these changes affect the entire groups involved.Parus major (Sibley and Monroe 1990, 1993) was split by Pä ckert et al. (2005) into P. major, P. minor and P. cinereus who also transferred P. bokharensis (Sibley and Monroe 1990, 1993) into P. major. The BirdLife Taxonomic Working Group supports the authors treatment of bokharensis because morphological, vocal and genetic differences are small, but the treatment of minor and cinereus as species is not followed owing to the authors own reservations about recognising cinereus as distinct from minor because of the minor morphological, vocal and genetic differences and due to uncertainty over taxonomic relationships in the westernmost Himalayan region which allows the possibility that major and bokharensis are connected to cinereus and cinereus to minor. Owing to this uncertainty it is not felt there is sufficient evidence to treat any of these taxa as distinct from major at the species level.
