Population justification: The global population is estimated to number 500,000-4,999,999 mature individuals (Partners in Flight 2019).

Trend justification:

The species is undergoing a moderate decline (Partners in Flight 2019). A remote-sensing study found that forest loss within its range over three generations was potentially 9% (Tracewski et al. 2016); thus the species may be declining by < 20% over three generations.
