Population justification: The global population is estimated to number > c.300,000 individuals (Wetlands International 2006), while national population sizes have been estimated at c.50-10,000 wintering individuals in China and c.100-10,000 breeding pairs in Russia (Brazil 2009).
Trend justification: The overall population trend is uncertain, as some populations are decreasing, while others are increasing, stable or have unknown trends (Wetlands International 2006). This species has undergone a small or statistically insignificant decrease over the last 40 years in North America (data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007).
