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

Trend justification:

The population is undergoing a small decline (Partners in Flight 2019). A remote sensing analysis found that forest within the range has been lost at a rate of 7% over three generations (Tracewski et al. 2016); thus the species may be declining at < 20% over three generations.
