Population justification: Although the population size of this species remains uncalculated, it has been suggested that it could be widespread in high altitude reserves of the Sichuan arc (B. Anderson in litt. 2016). The species has recently been discovered in areas outside of its previously known range (Rheindt 2004). Data from citizen science platforms have further expanded known occurrences of this species (eBird 2019). While previously estimated to have a population size of about 700 mature individuals, it is likely that this number is in fact much higher.

Trend justification: The population trend is unknown, but there do not appear to be imminent threats with the potential to be driving ongoing declines in the species.
