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 stable, hence the species does not approach the threshold 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.
Partners in Flight (2017) places the population size at 11,000,000 mature individuals.
This species has undergone a small or statistically insignificant decrease over the last 40 years in North America (data from Breeding Bird Survey and Christmas Bird Count; Sauer et al. 2017, Meehan et al. 2018), but the population appears have stabilised since the mid-1980s. Therefore, the trend is considered here to be stable. Note, however, that these surveys cover less than 50% of the species's range in North America.
