Population justification: The population estimate for Costa Rican Important Bird Areas is 2,500-3,900 mature individuals (J. Criado et al. in litt. 2007, Sánchez et al. 2009), implying that there are fewer than 10,000 mature individuals in total, thus the population is placed in the band for 2,500-9,999 mature individuals, probably equivalent to a total population of 3,700-15,000 individuals.
Trend justification: A slow to moderate and on-going population decline is suspected based on rates of habitat loss within the species's range.
