Population justification: The global population size has not been quantified, but this species is described as 'uncommon' (Stotz et al. 1996).
Trend justification: Slow to moderate declines are likely to be occurring, owing to rapid and on-going habitat destruction and degradation throughout this species's range. However, precise data on the magnitude of these declines are lacking.
