Population justification: The global population is inferred to number 5,100,000 mature individuals (Partners in Flight 2019).
Trend justification: The species has been undergoing a large, significant decline at an average rate of 1.5% per year between 1970 and 2017 (Partners in Flight 2019). Short-term trends however suggest that the population has been stable or increasing over the past ten years (Pardieck et al. 2018). This may be because end years have a disproportionate affect on analyses, and the data shows an extremely rapid increase in 2014 and 2015. The overall, general trend does, however, appear to be a decline; and so the trend is precautionarily retained as such.
