Population justification: The population is estimated to number 2,500-9,999 mature individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.
Trend justification: The species is suspected to be declining at a moderate rate, owing to on-going forest conversion driven by a slowly expanding human population within its range. However, significant measures have been taken to safeguard forests in Arunachal Pradesh and Bhutan, lending hope that suitable habitat can be conserved.
