Population justification: The population has been estimated to number 50-230 individuals (Riley 2002, Collar et al. 2013, R. Martin in litt. 2016), equating to 33-153 mature individuals, rounded here to 30-150 mature individuals.
Trend justification: Small scale clearance at the edges of remaining forest continues, and clearings have also been created and maintained on the ridge in a few places for using mist nets to catch bats for food (R. Martin in litt. 2016). Therefore, the population is likely in decline.
