Population justification: The global population is estimated to number c.25,000-100,000 individuals (Wetlands International 2016). At least 20,000 (up to 38,000) individuals move past Point Barrow, Alaska, in autumn (Maftei et al. 2014). The population in Russia has been estimated at c.100-10,000 breeding pairs and c.50-1,000 individuals on migration (Brazil 2009). The population in Greenland is estimated at 0-5 pairs (BirdLife International 2015).

Trend justification: The population trend is difficult to determine because of uncertainty over the extent of threats to the species (del Hoyo et al. 1996).
