Population justification: The global population is estimated to number 500,000-4,999,999 mature individuals (Partners in Flight 2019).
Trend justification: The population is undergoing a small decline (Partners in Flight 2019). A remote sensing study found that habitat within the range has been lost at a rate of 7% over three generations (23.4 years; Tracewski et al. 2016); therefore the species is likely declining at <10% over three generations.
