Population justification: The global population is estimated to number 9,600,000 mature individuals (Partners in Flight 2019).
Trend justification: This species has been undergoing a large, significant decline at an average rate of -1.66% per year between 1970 and 2017 (Partners in Flight 2019; Rosenberg et al. 2019). Short-term trends suggest that declines have slowed down in recent years, amounting to 5% over the past ten years, although this number is non-significant (Pardieck et al. 2018).
