Population justification: The global population size has not been quantified, but the species is described as variously scarce to common in different parts of its range (del Hoyo et al. 2005).

Trend justification: The population is suspected to be in decline owing to on-going habitat loss and degradation (del Hoyo et al. 2005). The likely rate of decline is suspected to fall in the band of 1-15% over three generations (Global Forest Watch 2020; Tchoumbou et al. 2020).
