Population justification: The population was previously estimated to number 2,500-9,999 mature individuals based on an assessment of recent records and surveys by BirdLife International (2001). However, recent evidence implies that the population could be smaller than this. The population in Yunnan, which accounts for the majority of records, has been estimated at 800-2,000 mature individuals, with only 6-50 mature individuals in the largest subpopulation (Han Lianxian in litt. 2012, 2013). The global population is therefore placed in the band for 1,000-2,499 mature individuals, roughly equivalent to 1,500-3,800 individuals in total.
Trend justification: A moderate and on-going population decline is suspected to be occurring, owing to on-going habitat loss and degradation across the species's range.
