Sichuan treecreeper

Description

The Sichuan treecreeper (Certhia tianquanensis) is a rare species of bird in the treecreeper family,Certhiidae.It was described as new to science (initially as a subspecies of the common treecreeper C.familiaris) in 1995 from 14 specimens taken at four sites in the mountains of western Sichuan,China.In 2002,it was realized that these birds constituted a distinct species,and subsequent research suggests it is closest to the Nepal treecreeper (C.nipalensis).
