Population justification: Partners in Flight (2019) estimate the population of mature individuals to total ~22,000,000.

Trend justification:

Partners in Flight (2019) currently estimate a ~2.1% decline in mature individuals each year, which equates to a ~19% reduction over a ten year period. Rates of decline are estimated to have decreased since 2006 and similar rates of decline are supported by Sauer et al. (2017). Although the North American Breeding Bird Survey estimated annual declines to be ~1.45% between 2010-2015, which corresponds to a ~14% across the stipulated ten year period, they conclude that estimates population reductions may reach up to ~32% in a worst-case scenario (Sauer et al. 2017). The rate of population decline is therefore tentatively placed in the band 10-29% over three generations.
