Population justification: The global population is estimated to number 79 million mature individuals (Partners in Flight 2019).

Trend justification: The species has been undergoing a small decline at an average rate of 0.3% per year between 1970 and 2017 (Partners in Flight 2019). Over the past ten years, the population has been stable (Pardieck et al. 2018).
