Notes

  • T3965 - Wetlands International 2012. Excluded from IWC trend analysis due to insufficient coverage. BirdLife International 2004b: Increased in Romania and Ukraine, stable in other countries except Turkey between 1990 and 2000
  • T1991 - 914. Improved data quality allows identification of a decrease.
  • T1992 - 898. Excluded from IWC trend analysis due to insufficient coverage. 64: Increased in Romania and Ukraine, stable in other countries except Turkey between 1990 and 2000
  • S8464 - Counts up to 2006 are comparable to those numbers with a five year mean of 20,089 birds between 2006 and 2010. The total of national estimates of wintering birds is 6,626-28,461 individuals (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). 11,450-17,000 pairs breed in BG, GR, RO, RU (70%), TR (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Further 100-160 pairs can be also in MK, MD, RS&ME and AL (BirdLife International, 2004). This yields an estimated 34,650-51,480 individuals based on breeding numbers, which agrees well with the estimate based on wintering numbers.
  • T6462 - Trends in breeding numbers: 2000-2012: 0.9872-1.0177, 1980-2000: 0.9956-1.0080 (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Trend analysis based on IWC data indicates uncertain/fluctuating trend in the short-term and large decrease in the long one (Nagy et al., 2014).
  • S8867 - 16,257 - 23,992 pairs in AL, BG, GR, MD, MK, RO, RS, RU, TR & UA
  • T6873 - Trends based on both breeding (BirdLife International 2015) and wintering (Wetlands International 2017) data indicate an overall stable trend.
