Population justification: The global population size has not been quantified, but the species is reported to be common to locally common (del Hoyo et al. 2002).

Trend justification: The population is suspected to be in decline owing to competition with other barbet species, woodpeckers and honeyguides and brood parasitism by honey guides (del Hoyo et al. 2002).
