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 small decline (Partners in Flight 2019). A remote-sensing study found that recent forest loss in the species's range was negligible (potentially 1% over three generations; Tracewski et al. 2016).
