Population justification: The global population size has not been quantified: it was estimated to number 9,604 individuals in Gola Forest in 1989. The forest covers less than 5% of the species's range, and so the population can be preliminarily estimated to number at least 190,000 individuals. Given the considerable uncertainty associated with this estimate, it is best placed in the band 100,000-499,999 individuals.
Trend justification: Given ongoing habitat destruction and fragmentation (del Hoyo et al. 2007), which continues to increase in at least part of its range (Arcilla et al. 2015), this species is likely to be in decline but measures of decline across its range are not currently available.
