Population justification: Wetlands International (2018) estimate the population at 100,000-200,000 individuals.
Trend justification: Although Wetlands International consider the current population trend to be unknown, it is suspected to be stable in the absence of evidence for any declines or substantial threats (del Hoyo et al. 1996).
