Notes

  • S3169 - 64: European breeding population 53,000-96,000 pairs (159,000 - 288,000 individuals). Winter counts increasing but small proportion of population included (700).
  • T3944 - Wetlands International 2012. Trend 1989-2007: +3.3% p.a. ? Increase Population trend levelled it off 1997-99, since when it has decreased.
  • T1935 - 914. Increasing in NW & Central Europe; decreasing in West Mediterranean and East Mediterranean/Black Sea.
  • T1936 - 898. Trend 1989-2007: +3.3% p.a. – Increase Population trend levelled it off 1997-99, since when it has decreased.
  • S8462 - Maximum IWC count total was 77,318 individuals in 1999. Total of wintering population estimates from BG, DE, ES, FR, IT, NL, PT and RO is 23,082-35,948. However, 186,000 individuals at Lake Burdur, Turkey, is mentioned by (Koop & für Feldornithologie, 2003), which indicates a larger population. 9,384-16,805 pairs estimated in AT, BE, BG, DE, DK, EE, ES, FR, HU, LT, LV, NL, PL, RO, SE, SI, SK, UK (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Further 40,787-78,135 pairs in AL, BY, HR, CZ, MK, RU, RS, CH, UA (BirdLife International, 2004). C. 50-300 pairs in NW Africa (Dodman, 2014). This yields a total estimate of 150,000-285,000 based on breeding numbers.
  • T6460 - The large short-term decrease based on IWC counts agrees with the overall large decrease (2000-2012: 0.9347-0.9579) calculated from the wintering population trend estimates in EU Member States mentioned below. However, an uncertain overall trend (2000-2012: 0.9687-1.0300, 1980-2012: 0.9890-1.0096) emerges from the breeding data (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.).
  • S8831 - 46,222-77,282 pairs in Europe except AZ (BirdLife International 2015). C. 50-300 pairs in NW Africa (Dodman, 2014).
  • T6791 - The IWC trend analysis suggests a statistically not significant but substantial short-term decline 2006-2015: 0.9630, S.E. 0.0357 (Wetlands International 2017). The short-term trend of the breeding population is unknown (BirdLife International 2015). The long-term trend is stable based on both the breeding and the non-breeding data.
