Population justification: The global population is inferred to number 1,700,000 mature individuals (Partners in Flight 2019).

Trend justification: The species has been stable between 1970 and 2017 (Partners in Flight 2019). Short-term trends suggest that the population in North America has increased by 17% over the past ten years, although this value is non-significant (Pardieck et al. 2018).
