Population justification: The global population is estimated to number 50,000-499,999 mature individuals (Partners in Flight 2019).

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 within the range (Tracewski et al. 2016).
