Taxonomy: Sitta canadensis Linnaeus, 1766, Canada.
A member of a species group that contains also S. whiteheadi, S. ledanti, S. krueperi, S. villosa and S. yunnanensis, and all sometimes thought to form a superspecies. Present species formerly treated as conspecific with S. whiteheadi and S. villosa; close relationship with these two supported by recent data on mitochondrial DNA, which indicate that all three form a sister-clade to S. krueperi and S. ledanti (no S. yunnanensis material was available for analysis), with a genetic distance of approximately 10% betwe..
