Population justification: The global population is inferred to number 11 million mature individuals (Partners in Flight 2019).

Trend justification: The species has been undergoing a moderate decline at an average rate of 0.7% per year between 1970 and 2017 (Partners in Flight 2019). Short-term trends suggest that the population in North America has been roughly stable over the past ten years (Pardieck et al. 2018).
