Population justification: The global population size has not accurately been quantified. Although somewhat locally distributed given its dependence on inundated or floating grasses, it is common where found (Clement 1999, Pratt and Beehler 2015, eBird 2022) with flocks of up to 50 reported in some areas (eBird 2022). Precautionarily, the population is here suspected to number 10,000-19,999 although this requires quantitative confirmation.

Trend justification: No population data are available on this species' trend. It is precautionarily suspected to be in slow decline owing to habitat degradation (especially the conversion of wet grasslands) and perhaps trapping, although eBird (2022) data suggest that, at least at key sites, populations have been relatively stable in the ten years to 2022.
