Notes

  • T6089 - Wetlands International 2012. Trend 1983-2007: +10.1% p.a. ? Increase.
  • T3583 - 914. Trends of rapid increase in Central Europe and decrease in W Mediterranean levelled off in 2000s.
  • T3582 - 898. Trend 1983-2007: +10.1% p.a. – Increase.
  • S8543 - 9,853-11.383 pairs in AT, BE, DE, DK, ES, FR, HU. IT, LV, NL. PL, PT, SI, SK (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.) and further 260-370 pairs in CH, HR and CZ (BirdLife International, 2004). This yields an estimate of 30,000-35,000 individuals. Sum of the national estimates for wintering birds yields an estimate of 29,376-41,526 individuals (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.) without CH. Adding an estimate of 11,345-18798 individuals for CH based on the IWC counts in 2008-2012 and adjusted for the 10,000 birds already reported by DE, produces a total of 40,721-60,324 individuals which agrees well with the national IWC totals. The upper limit of the estimate is increased to account for the increase of the population.
  • T6537 - Both the trend analysis based on IWC counts and the overall trend calculated from the national trends in breeding numbers show large increases both for the short- and the long-term. IWC: 1988-2012: 1.0628±SE 0.0032, 2003-2012: 1.0262±0.0069 (Nagy et al., 2014). Breeding trends: 2000-2012: 1.0098-1.0233, 1980-2012: 1.0045-1.0089 (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.).
  • T6947 - Increasing trend is also confirmed by breeding data (BirdLife International 2015)
