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 (283).
  • 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 - Continued increase based on breeding numbers (BirdLife International 2015), but stabilized based on wintering numbers (Wetlands International 2017).
