Population justification: The global population is estimated to number c.250,000-1,300,000 individuals (Wetlands International 2006), while the population in Russia has been estimated at <100 breeding pairs (Brazil 2009).
Trend justification: The overall population trend is decreasing, although some populations 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/Christmas Bird Count: Butcher and Niven 2007) Note, however, that these surveys cover less than 50% of the species's range in North America.
