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