Population justification: The global population is estimated to number 30,000,000 mature individuals (Partners in Flight 2019).
Trend justification: The species has been overall stable over the last 50 years (Partners in Flight 2019). Short-term trends however suggest that the population has declined by 11% over the past ten years (Pardieck et al. 2018).
