Notes

  • S3740 - A pioneering breeding population of 180-210 individuals is becoming established in France, The Netherlands and Italy. Up to 5,000 present in France & Italy in winter (Hafner 2000).
  • T5423 - Wetlands International 2012. Trend 1989-2006: +3.9% p.a. ? Increase.
  • T2331 - 898. Trend 1989-2006: +3.9% p.a. – Increase.
  • S8490 - European Topic Centre on Biological Diversity (in prep.) and BirdLife International et al. (in prep.) estimates 4,936-7,473 pairs in ES, FR, NL, IT, AT, SK, HU, RO, BG, PL. Lawicki (2014) accounted for an additional 6,546-12,750 pairs in BY, GR, UA, SR. HR, LT and LV. Possibly an additional 1,550-5,152 pairs in AL, MD, RU (50%), TR and UA based on BirdLife International (2004). This yields a total estimate of 13,032-25,375 pairs, i.e. 39,000-76,000 individuals. Possibly, some birds in the Volga delta belong to the Western Asia/South-west Asia population. European Topic Centre on Biological Diversity (in prep) reported 11,771-18,350 individuals wintering in ES, BE, NL, DE, IT, SI, BG, RO.
  • T6485 - Breeding trends based on European Topic Centre on Biological Diversity (in prep.) and BirdLife International et al. (in prep.): 2000-2012: 0.9930-1.0768, 1980-2012: 0.9972-1.0242. More pronounced increase in wintering numbers in Europe based on data from European Topic Centre on Biological Diversity (in prep.) and BirdLife International et al., (in prep.): 2000-2012: 1.0383-1.0701, 19980-2012: 1.0267-1.0445. However, this could be the result of shift of the wintering range as a result of milder climate.
  • S8843 - 20,248-32,928 pairs in Europe (BirdLife International 2015). Possibly, some birds in the Volga delta belong to the Western Asia/South-west Asia population.
  • T6812 - In the short-term, increased based on breeding numbers (BirdLife International 2015), but stabilized based on wintering numbers (Wetlands International 2017). In the long-term, increase based on both source.
  • S9356 - The size of the breeding population is estimated at 38,811-60,366 pairs, or 120,000-180,000 individuals after rounding in AL, AT, BG, BY, ES, FR, GE, GR, HR, HU, IT, LT, LV, MD, MK, NL, PL, RO, RS, RU, SK, TR, UA, GB, BA, BE, DE based on data from the period of 2007-2019 (BirdLife International, in prep.). The size of the wintering population is estimated at 49,000-82,000 individuals in AL, BA, BE, BG, CH, CZ, DE, ES, GE, GR, HR, IT, LU, MD, ME, MK, NL, RO, RS, SI, TR, UA, XK, CY, FR, HU, PL, PT, SK, GB (BirdLife International, in prep.), DZ (Nadjiba & Samir, 2020), EG (Hamada & Mossad, 2020), MA (Amhaouch et al., 2020) based on data from the period of 2007-2019. The highest annual IWC count total between 2014–2018 was 48,795 individuals (Nagy & Langendoen, 2020).
  • T7453 - Based on BirdLife International (in prep.), it is estimated that the breeding population has increased by 40-51% in AT, BA, BE, BG, BY, DE, ES, FR, GR, IT, LT, LV, NL, PL, RS, RU, UA, GB, AL between 2009 and 2018. No quantitative trend information is available from GE, HR, HU, MD, MK, RO, SK, TR. It has also increased by 108-149% in AT, BA, BE, BG, BY, FR, GR, HR, HU, IT, LT, LV, NL, PL, RO, RS, RU, SK, UA, GB between 1980 and 2018. No quantitative trend information is available from DE, ES, GE, MD, MK, TR, AL. Based on the same source, it is estimated that the wintering population has increased by 131-205% in BE, BG, CH, CZ, DE, ES, FR, GR, LU, NL, PL, PT, RO, SI, SK, AL, MA between 2009 and 2018. No quantitative trend information is available from BA, CY, GE, HR, HU, IT, MD, ME, MK, RS, TR, UA, GB, XK, DZ, EG. It has also increased by 408-620% in BE, BG, CH, CZ, DE, ES, FR, GR, HU, IT, LU, NL, RO, RS, SI, SK, AL between 1980 and 2018. No quantitative trend information is available from BA, CY, GE, HR, MD, ME, MK, PL, PT, TR, UA, GB, XK, DZ, EG, MA. Based on IWC data, Nagy & Langendoen (2020) reported increasing populations for each of the periods of 1988-2018, 2001-2018 and 2009-2018.
