Population justification: The global population size has not been quantified, but the species is described as fairly common to common throughout much of its range (del Hoyo et al. 2003).

Trend justification: This species is able to thrive in some edge and secondary habitats (del Hoyo et al. 2003), thus its population is suspected to be at least stable.
