Population justification: The global population is inferred to number 23 million mature individuals (Partners in Flight 2019).
Trend justification: The species is increasing at an average rate of 2% per year (Partners in Flight 2019). Short-term trends suggest that the population in North America increased by 11% over the past ten years (Pardieck et al. 2018)
