Population justification: Delany and Scott (2006) estimate the population to be 150,000-300,000 individuals.

Trend justification: Although Wetlands International consider the population to be increasing, the population is suspected to be in decline owing to unsustainable levels of exploitation (del Hoyo et al. 1996).
