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). The population trend appears to be increasing, 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 extremely 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 estimated to number 42 million mature individuals (Partners in Flight 2020).
Trend justification
The species has been undergoing a small decline at an average rate of 0.25% per year between 1970 and 2017 (Partners in Flight 2019; Rosenberg et al. 2019). Short-term trends however suggest that this decline is historical; the population has been increasing by 6% over the past ten years, though this value is non-significant (Pardieck et al. 2018).
