Population justification: Partners in Flight estimate the global population to number 3 million mature individuals (A. Panjabi in litt. 2017).
Trend justification: This species has undergone a significant decline over the last decades in North America (69% decline between 1974 and 2014 based on Partners in Flight, A. Panjabi in litt. 2017). Recent information the North American Breeding Bird Survey only shows non-significant declines in this species, which would not approach the threshold for listing as Vulnerable (Sauer et al. 2017). Using data from 2006 (three generations ago) to 2015 gives an annual decline of 0.56% (2.24% decline to 1.36% increase). Extrapolating these trends forwards would give an overall population reduction of 6.52% (23.80% reduction to 17.60% increase) over the next three generations. Population reductions have been occurring at this approximate rate for some time now (at least 5 years).
