Population justification: Partners in Flight estimate the global population to number 570,000 mature individuals (A. Panjabi in litt. 2017).

Trend justification: Rosenberg et al. (2016) estimate the population reduction between 1970 and 2014 to be 72%, which roughly equates to 26.8% over three generations (10.8 years). Short term population trends from the North American Breeding Bird Survey (Sauer et al. 2017) show an annual decline of 1.31% (3.70% decrease to 1.83 increase) between 2005 and 2015. This equates to a reduction of 13.3% (33.4% decrease to 21.6% increase) over three generations. Even when looking at year by year records from Sauer et al. (2017), the species’s rate of decline has not met or approached the threshold for Vulnerable (reduction of 30% over three generations) since 2008, and so the rate of decline has been below the threshold for Vulnerable for some time. Partners in Flight estimate the half-life of the species to be 26 years though (Rosenberg et al. 2016), which would equate to a decline of 25.0% over the next three generations.
