Population justification: In Liberia, the population is estimated to number c.6,000 pairs, roughly equivalent to 18,000 individuals. Conservatively, this is taken to constitute 25-49% of the species's range, so a very preliminary estimate of the overall population size is 36,000-72,000 individuals. It is precautionarily placed in the band 20,000-49,999 individuals.
Trend justification: The population is suspected to be in decline owing to extensive clearance and degradation of forest across its range.
