Population justification: Delany and Scott (2006) estimate the population to be 60,000 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).
