Population justification: The global population is estimated to number fewer than 50,000 mature individuals (Partners in Flight 2019); thus it is here placed in the band 20,000-49,999 mature individuals.

Trend justification:

The species is undergoing a large, significant decline (Partners in Flight 2019), which is thought to be caused by low levels of habitat loss within the range (Tracewski et al. 2016).
