Population justification: The total population size is unknown. The species is known by just a few scattered records in this inaccessible and poorly known area, but it appears to be genuinely rather scarce and localised and is seemingly absent from extensive areas of seemingly suitable habitat (Madge 2020). Using a line transect method, a population of 18-33 individuals was estimated in a 7.4 km2 study site (Ju and Golok 2013). Considering also an estimated c. 137,000 km2 of highly suitable habitat (and a further c. 200,000 km2 of medium suitability) (Li et al. 2023), the population probably numbers at least in the high tens of thousands.

Trend justification: Populations are thought to have stabilised through targeted conservation action including establishing a community-conserved area for the species and working with local herdsmen. Grazing has been restricted in critical habitat during nesting season, which has resulted in increased bunting numbers (Ju and Golok 2013). Additionally, climate change is not projected to cause a significant change in area of habitat: climate modelling showed that the area of habitat with high suitability is likely to increase marginally between now and 2050 (Li et al. 2023). In the absence of evidence for declines in the last ten years, the global population trend is suspected to be stable.
