Population justification: The global population is estimated to number 2,000,000 mature individuals (Partners in Flight 2020).

Trend justification: The species has been undergoing a moderate decline between 1970 and 2019 at an average rate of 1.1% per year (Partners in Flight 2020). Short-term trends however suggest that the decline has stopped and that the species has been stable over the past three generations (11.1 years) (Meehan et al. 2018; Pardieck et al. 2018). Therefore, the population is here assessed as stable.
