Subspecies

Parus montanus (Sibley and Monroe 1990, 1993) was split by Eck and Martens (2006) into Willow Tit (Poecile montanus) and Sichuan Tit (Parus weigoldicus) based on morphological and vocal evidence, but this treatment is not followed by the BirdLife Taxonomic Working Group owing to considerable overlap in morphological characters between weigoldicus and parapatric subspecies affinis of Willow Tit (Poecile montanus) and because the song-type of weigoldicus is part of the montanus repertoire. 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.
Considered by some authors as a subspecies of Willow Tit (Poecile montanus).
