Population justification: The European population is estimated at 265,000-1,650,000 calling or lekking males, which equates to 531,000-3,310,000 mature individuals or 797,000-4,970,000 individuals (BirdLife International 2015). Europe forms approximately 50% of the global range so a very preliminary estimate of the global population size is 1,594,000-9,940,000 individuals. The global population was previously estimated to number 2,000,000-2,600,000 individuals (Wetlands International 2006). The upper estimate of the European population size is considerably larger than the Wetlands International (2006) global estimate. The extrapolated European population size is therefore used here and the population placed in the band 1,500,000-9,999,999 individuals.

Trend justification: The overall population trend is decreasing, although some populations have unknown trends (Wetlands International 2015). There is evidence to suggest that the European population (265,000-1,650,000 calling or lekking males, occupying c. 50% of the global breeding range) has declined by less than 25% in 15.9 years (three generations). 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.
