Population justification: The global population size has not been quantified, but this species was described as 'fairly common', prior to being split (Stotz et al. 1996). This species tolerates converted habitats (del Hoyo et al. 2004) and its population is therefore suspected to be stable.
Trend justification: This species tolerates converted habitats (del Hoyo et al. 2004) and its population is therefore suspected to be stable.
