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

Trend justification: A slow population decline is suspected to be occurring, owing to on-going habitat loss and degradation throughout the range, although data on the magnitude of this change are lacking.
