Subspecies
No subspecies.
A member of a species group that contains also Algerian Nuthatch (Sitta ledanti), Krueper's Nuthatch (Sitta krueperi), Snowy-browed Nuthatch (Sitta villosa), Yunnan Nuthatch (Sitta yunnanensis) and Red-breasted Nuthatch (Sitta canadensis), and all sometimes thought to form a superspecies. Formerly treated as conspecific with Snowy-browed Nuthatch (Sitta villosa) and Red-breasted Nuthatch (Sitta canadensis). Cclose relationship with these two supported by recent data on mitochondrial DNA, which indicate also a more distant relationship to Krueper's Nuthatch (Sitta krueperi) and Algerian Nuthatch (Sitta ledanti) (no Yunnan Nuthatch (Sitta yunnanensis) material was available for analysis). Earlier taxonomic separation of present species from Red-breasted Nuthatch (Sitta canadensis) based on studies of vocalizations, together with those of breeding biology and behaviour. A nesting pair of nuthatches resembling present species and Snowy-browed Nuthatch (Sitta villosa) found at 2000 m in Altai Mts of extreme southern Siberia (at Aktru, south of Karay) in 2006. This could represent a remarkable range extension of either species, or an as yet undescribed species, but requires verification.
