Justification of Red List category
Although this species may have a restricted range, it is not believed to approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km² combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size may be moderately small to large, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Population justification
The population has not been quantified, but the species is described as fairly common to common (Remsen Jr. and Greeney 2020), with observational records frequent across the range (eBird 2023). It is suspected to number less than 50,000 mature individuals (Partners in Flight 2022); therefore it is here tentatively placed in the band 20,000-49,999 mature individuals.
Trend justification
The population trend has not been investigated. Tree cover within the range is lost at a rate of 4% over ten years (Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). Apart from forests, the species is also found in secondary growth, plantations and fragmented forest (Remsen Jr. and Greeney 2020); consequently, the current rate of tree cover loss may not be affecting the population. Therefore, in the absence of evidence for any declines or substantial threats, the population is suspected to be stable.
The species occurs on the Pacific slopes in Costa Rica and western Panama.
The species inhabits forests, secondary growth and plantations (Remsen Jr. and Greeney 2020).
