family Sittidae. Long regarded as a subspecies of the white-cheeked
nuthatch (Sitta leucopsis), it nevertheless differs significantly in
morphology and vocalizations. It is a medium-sized nuthatch, measuring
about 13 cm (5.1 in) in length. Its upper body is a dark gray-blue.
The cheeks and throat are a white buff-orange, turning to a rich
cinnamon on the underparts. The bird is endemic to areas in southeastern
Tibet and west central China, inhabiting coniferous mountain forests.
The species was first described in 1891 from a specimen collected in
China's Haidong Prefecture. The name commemorates the Russian explorer
Nikolaï Prjevalski, who discovered the species in 1884. Little is known
about its ecology. It was awarded the rank of full species in 2005,
separating it from the white-cheeked nuthatch. As of 2014, S.
przewalskii does not have a full threat-status evaluation by BirdLife
International or the IUCN. A 2014 phylogenetic study found the species
to be at the base of the nuthatch evolutionary tree, dispelling a
hypothesis that S. przewalskii could belong to the same species as S.
carolinensis.
