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. The population structure is unknown, but it is tentatively assumed that the species forms several small, disjunct subpopulations (see eBird 2020).

Trend justification: A slow to moderate population decline is suspected based on rates of habitat loss within the species's range.
