Population justification: The population size is preliminarily estimated to fall into the band 10,000-19,999 individuals. This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals. The eastern population extends into western Côte d'Ivoire (Goin Débé and Cavally Forest Reserves), covering an area of at least 18,000 km2, where it is locally common; the population has been estimated to lie in the region of 20,000-50,000 birds. However, this estimate is considered optimistic (H. Rainey in litt. 2007). and extrapolated data for the total population must be treated with caution as the species appears to be very rare and localised in the western part of its range (J. Lindsell in litt. 2007).
Trend justification: The total population is suspected to be declining very rapidly in line with severe habitat loss and degradation.
