Population justification: The global population is estimated to number 680,000 mature individuals (Partners in Flight 2019).
Trend justification: The species has been undergoing a moderate decline between 1970 and 2017, at an average rate of 1% per year (Partners in Flight 2019; Rosenberg et al. 2019). Short-term trends suggest a rate of decline of 10% over the past ten years, though this value is non-significant (Pardieck et al. 2018).
