Population justification: The global population is estimated to number 110 million mature individuals (Partners in Flight 2019).

Trend justification: The species has been undergoing a moderate decline at an average rate of 1.38% per year between 1970 and 2017 (Partners in Flight 2019; Rosenberg et al. 2019). Short-term trends suggest that the decline has slowed down in recent years and that the species has been declining by 7% over the past ten years, though this value is non-significant (Pardieck et al. 2018).
