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 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.
Partners in Flight estimate the global population to number 6.8 million mature individuals (A. Panjabi in litt. 2017).
This species has undergone a large and statistically significant increase over the last 50 years in North America (>1000% increase based on the North American Breeding Bird Survey [Sauer et al. 2017] and Partners in Flight [A. Panjabi in litt. 2017]). Short-term trends show an increase of 721% over the last three generations (Sauer et al. 2017). Note, however, that these surveys covered less than 50% of the global range.
