Population justification: The global population is estimated to number 4.8 million mature individuals (Partners in Flight 2019).

Trend justification: The species has been undergoing a moderate decline at an average rate of 0.4% per year between 1970 and 2017 (Partners in Flight 2019). Short-term trends however suggest that this decline is historical and that the species has been stable over the past ten years (Pardieck et al. 2018).
