Population justification: This species's breeding population in Costa Rican Important Bird Areas (IBAs) has been estimated at 190-330 mature individuals (Sánchez et al. 2009). The 2007 estimate for the breeding population in the IBAs of Panama was given as 1,050-4,245 mature individuals, which is regarded by some as an overestimate (J. Criado et al. in litt. 2007), and is limited by a lack of sufficient data from the core of its likely range in Panama, La Amistad International Park (G. Angehr in litt. 2011). On the basis of this information, the species's global population is conservatively placed in the band for 1,000-2,499 mature individuals, probably equivalent to a total population of 1,500-3,800 individuals.

Trend justification: The population is suspected to be declining rapidly, in line with rates of habitat loss and degradation.
