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

Trend justification: The population is suspected to be in decline owing to fires, over-grazing by cattle, slash-and burn agriculture and selective logging (del Hoyo et al. 2004).
