Population justification: The global population is estimated to number 5,100,000 mature individuals (Partners in Flight 2019).

Trend justification: The species has been undergoing a large decline at an average rate of 2.2% per year between 1970 and 2017 (Partners in Flight 2019). Short-term trends however suggest that the population trend is stabilising, so that the species has declined very slowly over the past ten years (Pardieck et al. 2018; see also Meehan et al. 2018).
