Geographic Range [top]
Range Description: There is evidence to suggest that the European population (200,000-510,000 pairs, occupying 50-74% of the global breeding range) has declined by up to 30% over ten years (three generations), but this may reflect shifts in breeding populations, populations in Asia are not thought to be declining and wintering populations in Africa appear to be increasing.

Population [top]
Population: The global population is estimated to number > c.160,000 individuals (Wetlands International, 2006), while the population in Russia has been estimated at c.100-100,000 breeding pairs and c.50-10,000 individuals on migration (Brazil 2009).
Trend Justification: Although Wetlands International consider the current population trend to be unknown, it is suspected to be stable in the absence of evidence for any declines or substantial threats (del Hoyo et al. 1996).
Current Population Trend: Stable
Additional data:
? Continuing decline of mature individuals: Unknown
? Extreme fluctuations: No ? Population severely fragmented: No
? Continuing decline in subpopulations: Unknown
? Extreme fluctuations in subpopulations: No ? All individuals in one subpopulation: No
