Population justification: Data from transect surveys in most forest patches within the majority of the species's known range were used to estimate the population at 2,469 individuals (with a 95% confidence interval of 1,401-4,365), which can be considered a maximum estimate of the world population. The confidence intervals for this estimate are taken for the species's population range. roughly equating to 930-2,900 mature individuals.

Trend justification: The population is suspected to have declined during a c.66% reduction in its range since the 1970s (Manu et al. 2005), probably owing to widespread forest clearance (Peach 2005). Forest within its range remains under pressure from humans (Peach 2005; A.U. Ezealor in litt. 2007; W. Cresswell in litt. 2007), thus it is still suspected to be declining, although the likely rate of population decline has not been estimated.
