Population justification: The global population is estimated to number 13 million mature individuals (Partners in Flight 2019).

Trend justification: The population has been overall stable between 1970 and 2017 (Partners in Flight 2019; Rosenberg et al. 2019). Short-term trends however suggest that the population is now increasing at a rate of 11% over the past ten years (Pardieck et al. 2018).
