Population justification: The global population is estimated to number 1,300,000 mature individuals (Partners in Flight 2020).
Trend justification: The species is undergoing a large increase (Partners in Flight 2020). Over the past three generations (18 years; Bird et al. 2020) the rate of increase equated to 88%, although it is noted that there is some data deficiency for the species (Pardieck et al. 2018).
