Population justification: The global population is estimated to number 4 million mature individuals (Partners in Flight 2019).
Trend justification: The species has been increasing at an average rate of 2.1% per year between 1970 and 2017 (Partners in Flight 2019). The rate of increase appears to be accelerating in recent years; short-term trends suggest that the population increased by <100% over the past ten years (Pardieck et al. 2018).
