Population justification: The global population is estimated to number 160,000 mature individuals (Partners in Flight 2019).

Trend justification: The species has been undergoing a slow decline at an average rate of 0.4% per year between 1970 and 2017 (Partners in Flight 2019). The population in North America has declined by 2.5% over the past ten years, thought this value is non-significant (Pardieck et al. 2018).
