Population justification: The total population has been estimated at between 21,000 and 166,000 individuals, with a likely figure of 37,000 individuals (Tøttrup et al. 2004). Assuming two-thirds of the individuals are mature, this equates roughly to 24,700 (14,000- 110,700) mature individuals.

Trend justification: The species's population is believed to be declining very slowly due to ongoing habitat loss and degradation (A. Tøttrup in litt. 2006; N. Burgess in litt. 2006). Between 2008-2019, 4.7% of forest was lost from this species's range (Global Forest Watch 2020), which equates roughly to a loss of 4.3% over three generations. As this species appears intolerant of habitat degradation, it is suspected that the population is declining at a similar rate. The overall rate of past decline is placed in the band 1-9% to account for uncertainty. Between 2016-2019, 3.4% of forest was loss from this species's range (Global Forest Watch 2020), which equates roughly to a loss of 8.3% over three generations. The overall rate of future decline is placed in the 1-15% band to account for uncertainties.
