Population justification: Partners in Flight (2019) estimate the global population to number 1.4 million mature individuals.

Trend justification: This species has undergone a large and statistically significant decrease. Over the past 51 years (1966-2017), data from the North American Breeding Bird Survey suggests an annual rate of decline of 3.2%, or 27.8% across a ten year period (Pardieck et al. 2018). However, when viewed across the most recent time period (2010-2017), declines are shown to have accelerated in recent years with annual declines measured at ~5.22% per year, or ~41% over ten years (Pardieck et al. 2018). The rate of past decline is therefore placed in the band 30-49%. However, recent data from the Audubon Christmas Bird Count (Meehan et al. 2018) and Partners in Flight's (2019) estimate of a 27 year half life for the species (22.6% decline over the next decade) suggest that the rate of decline may have slowed over the past few years; if this continues the species may warrant downlisting in the near future.
