Population justification: The global population is estimated to number 9,100,000 mature individuals (Partners in Flight 2019).
Trend justification: The population is undergoing a moderate decline (Partners in Flight 2019; Rosenberg et al. 2019). Short-term trends suggest a decline of 7% over the past ten years, though this number is non-significant (Pardieck et al. 2018).
