Population justification: In Myanmar, on the basis of previously reported population densities and extent of suitable habitat, the population was estimated in 2004 to be 5,152-8,586 pairs, equating to 10,300-17,100 mature individuals, or roughly 15,000-26,000 individuals in total. More recently it has become evident that the species has suffered very rapid declines and the population in 2019 is much lower, and is now believed to be fewer than 2,500 mature individuals and may be even fewer, although there has not been an attempt to update the population estimate using the same methodology (C. Zöckler in litt. 2015, Lay Win et al. 2015, T. D. W. Aung in litt. 2016). As such, the population is currently placed in the band 1,000-2,500 mature individuals.

Trend justification: A very rapid decline has been estimated over the past three generations from a repeat survey of almost all presence sites, owing to very high rates of deforestation. This population decline is expected to become extremely rapid over the next ten years on the basis of the expected rate of deforestation in Myanmar, following uncertainty over the future status of the protected areas that are the last refuge for the population.
