Notes

  • S3377 - 64: Breeding population in relevant countries 126,000-135,000 pairs (378,000-405,000 individuals).
  • T2074 - Population wintering in Central Europe apparently decreasing since early 1990s (700).
  • T5284 - Wetlands International 2012. Trend 1987-2007: +3.5% p.a. ? Increase.
  • T2075 - 914. Increasing Northern Europe, stable Central Europe
  • T2076 - 898. Trend 1987-2007: +3.5% p.a. – Increase.
  • S8469 - Based on Bregnballe et al. (2014). European Topic Centre on Biological Diversity (in prep.) and BirdLife International et al. (in prep.) data for relevant countries add up to 494,000-529,000 individuals.
  • T6467 - European Topic Centre on Biological Diversity (in prep.) and BirdLife International et al. (in prep.) suggest an increase of 2-4% p.a. increase for breeding birds during the period of 2000-2012, and 5% p.a. for the period of 1980-2012. IWC trend analysis of wintering birds suggests a large decline (-1.72±0.69% p.a.) during the period of 2003-2012 (Nagy et al. 2014) or stable/fluctuating trend (van Roomen et al. 2014) and a rapid increase in the long-term (Nagy et al. 2014, van Roomen et al. 2014).
  • S8837 - Based on Bregnballe et al. (2014). BirdLife International (2015) data for relevant countries add up to 190,324-216,893 pairs, i.e. 571,000-651,000 individuals.
  • T6801 - BirdLife International (2015) reports increase both for the long- and the short-term with indications that the population growth is slowing down. Wetlands International (2017) reports similar pattern based on the IWC data, but the short-term trend for 2006-2015 is stable.
