Population justification: The global population is estimated to number > c.1,200,000 individuals (del Hoyo et al. 1996), while the population in Russia has been estimated at c.100-100,000 breeding pairs and c.50-10,000 wintering individuals (Brazil 2009).

Trend justification: The population is suspected to be in decline owing to predation by invasive species and ongoing habitat destruction.
