This poorly-known species qualifies as Vulnerable because it is thought to have a small population, which is inferred to be in decline as a result of on-going habitat loss and degradation.

Erithacus obscurus Collar and Andrew (1988)
12.5-14.5 cm. Small, skulking robin. Male has black throat and breast and white rest of underparts, dull dark blue upperparts, white basal two-thirds to outer tail feathers and dark legs and feet. Similar spp. Male Siberian Blue Robin L. cyane has white throat and breast. Female has buffish underparts, white undertail-coverts, more buff-coloured tail and paler pinkish legs. Voice Song rather shrill phrases whr'ri-whr'ri and chu'ti-chu'ti alternated with purring trills, hdrriiii-ju'ju and uu ji'uu. Also soft, subdued tup contact notes.
Its habitat requirements and altitudinal range are poorly known. In Gansu, there are historical records from bamboo thickets on the tops of ridges dividing valleys at 3,050-3,350 m. More recent records in Sichuan are from temperate zone forest. Almost all of the individuals found during the 2011 survey in Shaanxi were on mountain slopes at 2,400-2,500 m in large, dense expanses of bamboo in open coniferous and mixed coniferous-broadleaved forest (Davies 2011, P. Alström in litt. 2012). Outside the breeding season, it has been recorded at 400 m in Thailand.
The main threat is likely to be the loss and fragmentation of forest. Forest cover has declined rapidly in Sichuan since the late 1960s, through exploitation for timber and clearance for cultivation and pasture, and substantial areas of temperate forest have been lost. Nong Bong Khai, Thailand, supported significant areas of secondary forest when the species was collected there, but the area has since been completely deforested for intensive agriculture and tourism. At the elevations and in the steep terrain where this species was found in the Qinling Mountains during the 2011 survey, there is said to be extremely little conversion of forest to agriculture, and although logging is a potential problem, very large areas are protected in this region (P. Alström in litt. 2012).
Conservation Actions Underway
CMS Appendix II. It is legally protected in Thailand. In China, a number of protected areas established for giant panda Ailuropoda melanoleuca contain suitable habitat, but the species's distribution and abundance in these areas is poorly known. It has been recorded from Jiuzhaigou and Baihe nature reserves (Sichuan) and Taibai Shan National Nature Reserve (Shaanxi). The survey in 2011 recorded seven males each in Foping and Changqing national nature reserves (Davies 2011). Conservation Actions Proposed
Survey protected areas in or near to its known range, research its population status and attempt to determine its wintering grounds. Research its habitat requirements. Strengthen protection and link, where possible, protected areas where it occurs and where new populations are discovered. Support recommendations to control logging and fire, and restore damaged giant panda habitat where this would benefit this species and other endemic temperate forest bird species. List it as a protected species in China.
