Population justification: The global population is inferred to number 1.4 million mature individuals (Partners in Flight 2022).
Trend justification: The species has been increasing at an average rate of 0.9% per year between 1970 and 2017 (Partners in Flight 2022). This equates to an increase of 10% over three generations (10.3 years). Short-term trends suggest that the population in North America has increased by 5% over the past ten years, though this value is non-significant (Pardieck et al. 2018).
