Population justification: The global population size has not been quantified, but this species was described as 'fairly common but patchily distributed', prior to being split (Stotz et al. 1996).

Trend justification: This species spreads into areas following deforestation (del Hoyo et al. 2004), and is therefore suspected to be increasing overall.
