Population justification: In Liberia, the population has been estimated at a minimum of 20,000 pairs (Gatter 1997) and thus, the total population has been placed in the range 20,000-49,999 individuals. However, the number given for Liberia may be a significant overestimate (J. Lindsell in litt. 2012), on one hand because the species may be absent from apparently suitable forest, on the other hand because the overall population may have experienced serious declines over the past three generations (14 years). New data are therefore required to refine this population estimate.
Trend justification: The population is suspected to be declining in line with high rates of forest clearance within the species's range. A population decline was evident in the Gola Forest in Sierra Leone by 1988-1989 (Allport et al. 1989). The species was seen twice during extensive surveys in 2007 (F. Dowsett-Lemaire and R. J. Dowsett per E. Klop in litt. 2007) and not since, while it was still seen frequently in the 1970s (J. Lindsell in litt. 2007, 2012). Reasons for the apparent decline in the Gola Forest are unknown, as there are no obvious changes in forest structure (J. Lindsell in litt. 2012).
