Notes

• S2988 - 64: European breeding population 99,000 - 170,000 pairs (297,000 - 510,000 individuals). About 70,000 included in winter counts (700).
• T1852 - Trends generally increasing (700).
• T5225 - Wetlands International 2012. Trend 1990-200: +3.9%: Increase.
• T1853 - 898. Trend 1990-200: +3.9%: Increase.
• T1851 - 914. Increasing in all parts of Europe except Central Europe, where 10 year trend is decreasing.
• S8452 - 88,811-135,046 pairs in Europe (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). In addition, 34,753-52,692 pairs in other European countries (BirdLife International, 2004). Thus the European population is estimated to be 371,000-563,000 individuals. Further, less than 5,000 individuals in North Africa (Dodman, 2014).
• T6450 - Long-term increase seems to have turned into rapid decline of -2.55±0.53% based on IWC data (Nagy et al. 2014). The IWC trends closely resemble the trend shown by the Pan-European Common Bird Monitoring Scheme EBCC et al., 2014). Incomplete data from the European Topic Centre on Biological Diversity (in prep.) and BirdLife International et al. (in prep.) indicate also similar changes (-2.84 - +0.12% p.a.) for 2000-2010 and -0.53 - +0.72% for 1980-2010.
• S8824 - 124,848-198,925 pairs in Europe without AZ and AM (BirdLife International 2015). Further, less than 5,000 individuals in North Africa (Dodman, 2014).
• T6780 - The short-term population growth rate of wintering birds is 0.9738 (SE 0.0313) indicating some decline (Wetlands International 2017), but breeding numbers show a stable trend stable (EBCC 2016) or uncertain (BirdLife International 2015). In the long-term, the population has strongly increased based on mid-winter counts (1988-2015; Wetland International 2017) or remained stable based on common bird monitoring (EBCC 2016).
