Population justification: The global population is estimated to number 3.5 million mature individuals (Partners in Flight 2019).

Trend justification: The species is undergoing a small decline, which is probably caused by low levels of habitat loss within the range (Tracewski et al. 2016, Partners in Flight 2019).
