Population justification: The global population size has not been quantified, but this species is described as 'uncommon and patchily distributed' (Stotz et al. 1996).

Trend justification: Population declines are suspected, particularly in Peru, where the species has become rare and local owing to habitat loss and degradation. The overall decline is suspected to be slow.
