Population justification: The global population is estimated to number c.190,000-380,000 individuals (Wetlands International 2015), the population in Russia is estimated at c.10,000-100,000 breeding pairs and c.1,000-10,000 wintering individuals (Brazil 2009). The European population is estimated at 4,000-7,000 pairs, which equates to 8,000-14,000 mature individuals (BirdLife International 2015).

Trend justification: The overall population trend is increasing, although some populations may be stable and others have unknown trends (Delany and Scott 2006). This species has undergone a small or statistically insignificant increase over the last 40 years in North America (data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007). The population trend in Europe is unknown (BirdLife International 2015).
