Population justification: The global population size has not been quantified, but the species is described as locally common in south-west Cameroon (del Hoyo et al. 2006).

Trend justification: The population is suspected to be in decline following reports of widespread deforestation on Bioko since 1990 (del Hoyo et al. 2006).
