Population justification: The global population size has not been quantified, but this species is described as 'fairly common' (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.
