Dull, short-billed treecreeper with a white throat, brown upperparts, and brown-suffused pale underparts. Restricted to mature montane coniferous stands, especially fir. Like other treecreepers, scrambles quickly up trunks and along branches with its tail held flat against the bark. Very similar to Hodgson’s Treecreeper, but Sichuan averages darker on the face and belly, with a different song: a long tinkling series of descending high notes. Call is high-pitched and sputtery, like a sped-up version of the song.
