Notes

  • S2144 - BirdLife International (2005) give estimate of 19,200 breeding pairs (57,600 individuals).
  • S8407 - 21,507-21,907 pairs in European breeding countries except HR (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). 60-70 pairs in HR (BirdLife International, 2004). North Africa: c. 150-250 pairs (Dodman, 2014). This yields a total estimate of 21,722-22,227 pairs, i.e. 65,000-67,000 individuals.
  • T6406 - European Topic Centre on Biological Diversity (in prep.) and BirdLife International et al. (in prep.) suggest an overall stable short-term trend (2000-2012: 0.9997-1.0025) and an increasing one for the long-term (1980-2012: 1.0009-1.0013).
  • S8959 - 21,567-21,977 pairs in European breeding countries. North Africa: c. 150-250 pairs (Dodman, 2014). This yields a total estimate of 21,722-22,227 pairs.
  • T7032 - Long-term trend: strong increase.
  • S9477 - The size of the breeding population is estimated at 15,933-21,989 pairs, or 48,000-66,000 individuals after rounding in CY, ES, FR, GR, HR, IT, PT, TR (BirdLife International, in prep.), MA (Amhaouch et al., 2020) and elsewhere in North Africa (BirdLife International, 2020) based on data from the period of 1998-2019. The highest annual IWC count total between 2014–2018 was 13,518 individuals (Nagy & Langendoen, 2020).
  • T7620 - Based on BirdLife International (in prep.), it is estimated that the breeding population has decreased by 56-56% (equivalent to 72-73% in 3 generations) in CY, ES, FR, GR, HR between 2009 and 2018. No quantitative trend information is available from IT, PT, TR, MA, DZ. It has increased by 9-12% in CY, ES, FR, IT between 1980 and 2018. No quantitative trend information is available from GR, HR, PT, TR, MA, DZ. Based on IWC data, van Roomen et al. (2018) reported stable trend for 1995-2017 (0.99) and uncertain trend for 2008-2017 (0.97). Based on updated IWC data and using different site selection and trend analysis techniques Nagy & Langendoen (2020) reported also stable trend for 1993-2017 (1.0053) and uncertain trend for 2008-2017 (0.9594). Based on the growth rate of the last 10 years, the population is projected to decrease by 63% in 3 generations compared to the population levels in 2008. Hence, the trends based on the IWC also indicate a decline but at a slower rate than the trend based on slightly incomplete breeding data.
