Population justification: Partners in Flight estimate the total population to number 200,000 mature individuals (Partners in Flight 2019, see also Panjabi et al. 2019). However, Wetlands International (2019) have placed the population at 25,000-100,000 individuals, roughly equivalent to 16,000-70,000 mature individuals. The species is poorly known, and given this uncertainty the extreme values are used and the population is placed in the range 16,000-200,000 mature individuals.

Trend justification: This species is tentatively suspected to be stable (per Partners in Flight 2019, Wetlands International 2019).
