Notes

  • T4363 - Wetlands International 2012. Trend 1989-2006: -1.4% p.a. ? Decline.
  • T1102 - 898. Trend 1989-2006: -1.4% p.a. – Decline.
  • T1101 - 914. Decreasing in E Mediterranean/Black Sea.
  • S8370 - Annual IWC count totals ahve exceeded over 20,000 individuals since 2006. The breeding population in Europe alone includes 3,121-5,752 pairs in AT, BG, HU, IT, RO, SI, SK (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Additional 7,171-15,610 pairs in AL, HR, GR, MK, RU, RS&ME, TR and UA (BirdLife International, 2004). This yields an estimate of 26,000-53,000 individuas using a conversion factor 2.5.
  • T6370 - The overall trend derived from national estimates for the breeding birds indicate a stable/fluctuating population, although data is updated only for 28% of the total population (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). However it is indicative and, although weakly, but supports the findings of the IWC trend analysis (Nagy et al., 2014). The population has increased in AT and SI, fluctuated in BG, HU and SK, but was unknown in IT and RO.
  • S9008 - 8,828-17,345 pairs in AL, AM, AT, AZ, BG, BY, FR, GE, GR, HU, IT, MD, ME, RO, RS, SI, SK, TR & UA. Using a conversion factor of 2.5, this yields an estimate of 22,000-43,000 individuals (BirdLife International 2015). IWC count totals were between 17,000 and 27,000 during the period of 2011-2015 without data from ES, which previously held about 17,000 individuals. Thus the wintering numbers can be estimated to between 34,000 and 44,000 individuals (Wetlands International 2017) and this new estimate is proposed to be used instead of the estimates based on data from the 1990s.
  • T7098 - Both the breeding and non-breeding data indicate stable/fluctuating population both in the long- and the short-term.
