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 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
Partners in Flight estimate the global population at four million mature individuals (A. Panjabi in litt. 2017).

Trend justification
This species has undergone a large, significant decrease over the last 50 years in North America (33.5% decline between 1966 and 2015 based on the North American Breeding Bird Survey [Sauer et al. 2017], or 29% decline between 1970 and 2014 based on Partners in Flight [A. Panjabi in litt. 2017]). Over the last three generations, the population declined non-significantly by 11.5% (Sauer et al. 2017). Note, however, that these surveys covered less than 50% of the global range.
