Population justification: The global population is estimated to number 320,000 mature individuals (Partners in Flight 2019). The species is considered to be fairly common to common.
Trend justification:
The species is undergoing a moderate decline (Partners in Flight 2019), which is thought to be caused by low levels of habitat loss (Tracewski et al. 2016).
