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

Trend justification: There are no data on population trends; however, the species is suspected to be declining at a slow to moderate rate, on account of hunting and forest loss and, perhaps in Cuba, competition with C. nasicus.
