Population justification: The species's habitat is now limited, and recent surveys suggest that the population size could be very small. A total of just 26 pairs/family groups has been estimated at Pic de Fon (Demey 2009), while surveys of East Nimba, Liberia in 2011 located only 5 pairs/small family groups, suggesting the subpopulation there may be significantly lower than 250 mature individuals (Dowsett-Lemaire and Phalan 2013, B. Phalan in litt. 2017). Therefore, the global population size is tentatively placed in the range 1,000-2,500 mature individuals, with <250 mature individuals per subpopulation; although further survey effort may mean that this requires revision.

Trend justification: The species's population is suspected to be declining in line with high levels of forest clearance across its range. The likely rate of decline, however, has not been estimated.
