Population justification: Partners in Flight estimate the total population to number 5-50 million individuals (A. Panjabi in litt. 2008). Previously, Wetlands International (2006) estimated 100,000-1,000,000 individuals.

Trend justification:

The species is tentatively assessed as being in decline due to habitat loss per Tracewski et al. (2016).
