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 within its range has been lost at a rate of 5% over three generations (Tracewski et al. 2016). Assuming that forest loss is continuing at this rate and population declines are proportional to forest loss, the species may be declining at < 10% over three generations.
