Population justification: This species's global population size has not been quantified, but it is described as 'uncommon' (Stotz et al. 1996). It is preliminarily placed in the band for 10,000-19,999 mature individuals on the basis that it may be approaching as few as 10,000 mature individuals.

Trend justification: The population is suspected to be in rapid decline owing to on-going deforestation, driven mainly by agricultural expansion, as well as timber extraction and mining (M. Sanchez in litt. 2013).
