Population justification: The global population is estimated to number 1.9 million mature individuals (Partners in Flight 2019).

Trend justification:

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