Population justification: No data on population size, however the species is generally regarded as common, and a five-figure population is suspected based on wide distribution (Ferguson-Lees & Christie 2001).

Trend justification: The population is suspected to be increasing locally as ongoing cutting of rain forest in West Africa is creating new areas of suitable habitat (Ferguson-Lees and Christie 2001). Between 1969-1973 and 2000-2004 the species was reported to have declined outside protected areas in Burkina Faso, Mali and Niger but numbers were stable or increasing within protected areas (Thiollay 2007). The trend outside protected areas was stable in Cameroon. The species has reportedly become much less common on fetish markets in West Africa, which may indicate a decline in some areas (Nikolaus 2011). Overall, the population is suspected to be stable.
