Sichuan Treecreepers

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) 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 recent results (Tietze et al., 2006) suggest it is closest to the Nepal Treecreeper.

This species is believed to be a relict species breeding in open old-growth stands of the conifer Faber’s Fir (Abies fabri) at high altitude (2,500-2,830 m), although it is thought to undertake localised altitudinal migrations in the winter (dropping down to at least 1,600 m).

It is known from five sites: Labahe Natural Reserve, Tianquin County; Dayi County; Shuanghe town, Ebian County; Wawu Shan, Hongya County, and Wujipung, Wolong Biosphere Reserve. Within this small area, the species is thought to be patchily distributed because it seems to be confined to old stands of the Faber’s Fir.

The species forages for invertebrates in the upper storey of large trees by creeping along branches and trunks.

Intensive logging of primary coniferous forests in the last century, even at high altitudes in the mountains of western China, has seriously reduced the potential range of this species.

The Wawu Shan table mountain has steep slopes which are inaccessible to lumberjacks in the absence of extensive road construction, but it is not yet formally protected, and there are plans to open up the regions for tourism by building a cable railway.

The estimated population is estimated to be less than 1000 individuals, occurring over a range of 19,690 km².
