Notes

  • S3234 - 700: Over 180,000 counted in early 2000s. The North American population is introduced and has not been included.
  • T1980 - 700: Population in Baltic region apparently decreasing since 1992.
  • T3962 - Wetlands International 2012. Trend 1983-2007: +2.9% p.a. ? Increase.
  • T1981 - 914. Increasing strongly in NW & Central Europe; decreasing in Baltic/Nordic.
  • T1984 - 898. Trend 1983-2007: +2.9% p.a. – Increase.
  • S8235 - Total of national breeding population estimates for AT, BE, BY, CH, DE, DK, EE, FI, FR, HU, IT, LT, LU, LV, NL, NO, PL, SE, SI, SK in the EU Birds Directive Art. 12 reporting process is 55,336-77,445 pairs. Estimates for the wintering season was 166,536-197,256 individuals with some countries holding significant wintering populations (e.g. SE) not included. Annual IWC count totals between 2003 and 2012 ranged between 97,374 (2012) and 180,992 (2009).
  • T6236 - Trend 2003-2012: +0.27±0.23% p.a. and for 1988-2012: 2.05±0.07% p.a. increase (Nagy et al., 2014). Short-term trend according to the EU Birds Directive Art. 12 reporting for breeding populations is 8-12% increase, and for wintering populations 7-8% increase. Long-trend for breeding populations 59-148% increase and for wintering birds: 14-32% increase.
  • S8866 - 57,821 - 80,972 pairs in AT, BA, BE, BY, CH, CZ, DE, DK, EE, FI, FR, HR, HU, IT, LI, LT, LU, LV, NL, NO, PL, SE, SI & SK
  • T6872 - Trends based on both breeding (BirdLife International 2015) and wintering (Wetlands International 2017) data show that the rate of decline has slowed down or even stabilised.
