Population justification: The global population is estimated to number 317,000-336,000 individuals (Wetlands International 2016). The breeding population in Europe is estimated at 5,000-6,000 pairs, which equates to 10,000-12,000 mature individuals (BirdLife International 2015). 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 2016). 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). In Europe the breeding and wintering population is estimated and projected to be decreasing by 50-79% between 2000, when declines are estimated to have begun, and 2038 (three generations) (BirdLife International 2015).
