Population justification: The global population is estimated to number 18 million mature individuals (Partners in Flight 2019).
Trend justification: The species is undergoing a moderate decline (Partners in Flight 2019; Rosenberg et al. 2019). Short-term trends suggest that the population has declined by 5% over the past ten years, though this value is non-significant (Pardieck et al. 2018).
