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.
