Population justification: The global population is estimated to number 39 million mature individuals (Partners in Flight 2019).

Trend justification: The species is increasing slowly (Partners in Flight 2019; Rosenberg et al. 2019). Short-term trends suggest an increase of 6% over the past ten years (Pardieck et al. 2018).
