Taxonomic CommentsThis species formerly was included in the genus Parus. It was transferred to Poecile by AOU (1997). The masculine ending of hudsonicus was feminized to hudsonica to agree with feminine Poecile (AOU 2000), however, reversing an earlier determination, David and Gosselin (2008) have shown that Poecile is in fact masculine, necessitating changing the gender to hudsonicus.
This species may constitute a superspecies with P. cincta and P. rufescens (AOU 1998). It exhibits little mtDNA genetic differentiation throughout the previously glaciated continental distribution; Newfoundland-Nova Scotia populations have distinct mtDNA haplotypes that differ from continental haplotypes by single restriction site changes (Gill et al. 1993). Phylogenetic analyses indicate that North American chickadees comprise two clades, hudsonica-rufescens-sclateri versus carolinensis-atricapilla-gambeli (Gill et al. 1993).
