Justification of Red List Category
This species has an extremely 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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the threshold 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.
Partners in Flight estimate the total population to number 50,000-500,000 mature individuals (Partners in Flight 2019, see also Panjabi et al. 2019).
The species is undergoing a moderate decline (Partners in Flight 2019). A remote sensing study found that between 2000 and 2012, forest within the species's range has been lost at a rate of 7% over three generations (Tracewski et al. 2016); thus the species may be declining by <10% over three generations.
