Population justification: The population in Cambodia was estimated at 294 displaying males or c. 600 individuals in 2009 (Gray et al. 2009a), but recently an extensive survey has reported a total of only 432 individuals (95% CI 312-550) (C. Packman in litt. 2013, Packman et al. 2014). 75-96 individuals remain in Nepal (Baral et al. 2013). No recent total population estimates are known from India, but >100 males were recorded in the country in recent surveys, with the population in D'Ering Wildlife Sanctuary potentially holding 50-60 territorial males (A. Rahmani in litt. 2016). Given these estimates, the total global population for this species is tentatively placed in the range 250-999 mature individuals. This equates to 375-1,499 individuals in total, rounded here to 350-1,500 individuals.
Trend justification: A very rapid decline in the global population is estimated to have occurred over the last three generations, based on figures from Cambodia. Current and projected rates of decline in the Cambodian population alone equate to a decline in the global population exceeding 80% in three generations (T. Gray in litt. 2006).
