Notes

  • S7799 - Fox et al. 2010. Presents new estimate of 200,000 but 37. indicates counts of 426,000-459,000 on migration at Lake Tengiz complex, Kazakhstan, in 1998-2006.
  • T5442 - Wetlands International 2012. Trend: +13.6% for 1987-2007 ? Uncertain.
  • S4015 - 876. Presents new estimate of 200,000 but 37. indicates counts of 426,000-459,000 on migration at Lake Tengiz complex, Kazakhstan, in 1998-2006.
  • T2530 - 898. Trend: +13.6% for 1987-2007 – Uncertain.
  • S8240 - National count totals (representing incomplete minimum estimates) for years 2010-2013 were 105,676, 248,042, 33,929 and 245,069 individuals for BG, CY, GR, IR, JD, RO, RU, SY, UA and TR.
  • T6255 - Uncertain trend due to high proportion of imputed values in 15 years out of the last 25 years.
  • S8877 - 400,000 individuals were counted in January 2017 in Bulgaria. This number is not yet included into the estimate because it is unclear whether it was just an influx from the Central European population.
  • T6887 - 1988-2012: +1,4% p.a..
  • S9202 - In the 2010s, high IWC count totals were obtained only in years when the winter conditions forced the population to concentrate on a few sites in BG indicating that count coverage is insufficient when birds winter further north. Based on the IWC count totals in seasons such as 2011/12, 2013/13 and 2016/17 (Nagy & Langendoen, 2020) and additional data of 352,292 birds from 3 sites along the Black Sea coast in BG in 2015/2016 and a total of 373,00 in BG, RO and UA in Dec. 2019. (N. Petkov in litt.). Therefore, population estimate has been revised.
  • T7267 - Fox & Leafloor (2018) estimated that the population has increased by 9.2% between 2003 and 2012 and also increased by 1.4% between 1988 and 2012. However, Ebbinge et al. (2018) noted that this population has declined. The IWC trend analysis suggest that the population has declined between 1992 and 2017 by 7% and nearly stabilised between 2008 and 2017 (Nagy & Langendoen, 2020). However, this assessment is based on very large imputing. The IWC count totals suggest a different pattern. Count totals indeed showed a decreasing tendency, but increasingly high counts have also occurred again from the mid-2000s. Comparing the count totals, nevertheless, suggest that even the high counts in the 2010s are much smaller than they were in the 1980s except in 2017. This supports the idea that the population has been stable in the long-term and fluctuations are mainly related to the widespread distribution of birds according to climatic conditions combined with low counting coverage.
