Population justification: The global population size has not been quantified, but the species is reported to be widespread and locally common but patchily distributed (del Hoyo et al. 2001).

Trend justification: It is an adaptable species, which tolerates logging and forest degradation and enters the transition forest/savanna zone, occurring in cocoa and coffee plantations with mature forest trees, and is not easily hunted (H. Rainey in litt. 2012, J. Lindsell in litt. 2013, F. Dowsett-Lemaire in litt. 2013). Nevertheless it is still suspected to be experiencing some declines.
