Population justification: The global population is estimated to number 360,000 mature individuals (Partners in Flight 2019).

Trend justification: Data from the North American Breeding Bird Survey show that the species has undergone a non-significant annual increase of 7.79% between 2007 and 2017 (Pardieck et al. 2018). Assuming that population trends continue at a similar rate to the present day, the species was likely stable or increasing over the past ten years. Long-term trends (1966-2017) from Audubon’s Christmas Bird Count however show an annual decline of 0.87% in this species. This would equate to a reduction of 8.4% over ten years. It is here precautionarily assumed that the positive short-term trends are a result of targeted conservation action, including translocations, habitat restoration and local hunting bans (Bateson et al. 2014; Hardy et al. 2017; Adkins et al. 2019; Johnson et al. 2020), without which the species would rapidly meet the threshold for listing as threatened.
