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.
The global population is suspected to number 50,000-499,999 mature individuals (Partners in Flight 2019).
The population is thought to be stable (Partners in Flight 2020). The species adapts well to habitat degradation; it occurs in secondary growth but is mostly absent from forest (Kroodsma and Brewer 2020), therefore it is not believed to be negatively affected by forest loss.
