Notes

  • S8414 - 349,675-414,182 pairs in AT, BE, BG, CH, CY, DE, ES, FR, GIB, GR, HU, IT, MT, NL, PL, PT, RO, SI, SK, TR (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Further 370-630 pairs in AL, MK, RS&ME (BirdLife International, 2004). Olsen & Larsson accounts for c. 10,000 pairs from the southern and eastern Mediterranean. This yields an estimate of 1,100,000-1,300,000 individuals.
  • T6413 - Increase in the long-term (1980-2012: 1.0060-1.0086), but stable in the short-term (2000-2012: 0.9941-1.0076). However, decreasing only in GIB, stable or fluctuating in AT, BE, CY, FR, GR, HU, IT, PL, unknown in NL, PT, RO and increasing in all other countries (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.).
  • S8968 - 400,397-515,868 pairs in Europe. Olsen & Larsson accounts for c. 10,000 pairs from the southern and eastern Mediterranean.
  • T7042 - Stable in the short-term, increased in the long-term.
  • S9488 - The size of the breeding population is estimated at 385,025-512,831 pairs, or 1,200,000-1,500,000 individuals after rounding in AL, AT, BA, BE, BG, CH, CY, CZ, DE, ES, FR, GE, GIB, GR, HR, HU, IT, ME, MK, MT, NL, PL, PT, RO, SI, SK, TR (BirdLife International, in prep.), MA (Amhaouch et al., 2020), DZ, TN (del Hoyo et al., 2020) based on data from the period of 2002-2019. The size of the wintering population is estimated at 380,000-410,000 individuals in AL, BA, CH, DE, ES, GR, HR, ME, MK, PT, RS, SE, TR, XK, BE, CZ (BirdLife International, in prep.), DZ (Nadjiba & Samir, 2020) and MA (Amhaouch et al., 2020) based on data from the period of 2007-2019, but no national estimates are available from the SE Mediterranean. The highest annual IWC count total between 2014–2018 was 382,641 individuals (Nagy & Langendoen, 2020).
  • T7632 - Based on BirdLife International (in prep.), it is estimated that the breeding population has increased by 7-11% in AT, BA, BG, CH, CY, DE, FR, GIB, GR, IT, MT, RO, SI, SK, AL between 2009 and 2018. No quantitative trend information is available from BE, CZ, ES, GE, HR, HU, ME, MK, NL, PL, PT, TR, MA, DZ, TN. It has increased by 104-306% in AT, BG, CH, CY, CZ, DE, FR, GE, GIB, GR, IT, MT, NL, RO, SI, SK, AL between 1980 and 2018. No quantitative trend information is available from BA, BE, ES, HR, HU, ME, MK, PL, PT, TR, MA, DZ, TN. Based on IWC data, Nagy & Langendoen (2020) reported stable trends for 2002-2018 (1.0012) and for 2009-2018 (0.9984).
