Justification of Red List category
This species has a very large range, and hence does not 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 is very large, and hence does not 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 global population is suspected to number 50,000-499,999 mature individuals (Partners in Flight 2022).

Trend justification
The population trend has not been investigated. Tree cover within the range is lost at a rate of 3% over ten years (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). The species occurs in a variety of habitats from forest and edges to humid scrub and open areas (Arizmendi et al. 2021) and as such it does not appear to be under imminent risk. Therefore, in the absence of evidence for any declines or substantial threats, the population is assessed as stable.
