Population justification: The global population is inferred to number 4.1 million mature individuals (Partners in Flight 2019).
Trend justification: The species has been undergoing a moderate decline at an average rate of 1.3% per year between 1970 and 2017 (Partners in Flight 2019). The population in North America has declined by 13% over the past ten years (Pardieck et al. 2018).
