Population justification: The global population is estimated at 3,400,000 mature individuals (Partners in Flight 2019).

Trend justification:

The species has been stable over the past five decades (Partners in Flight 2019; Rosenberg et al. 2019). Over the past ten years, the population is increasing, though this is statistically non-significant (Pardieck et al. 2018).
