Notes

  • S5698 - Earlier estimates, based on winter counts, were considerable under-estimates. Estimate increased in line with NW Europe population, and within range of Russian breeding population in 64.
  • S8567 - The average count total is merely 4,784 individuals during 2008-2012 with a maximum of 10,714 individuals in 2008. The historic maximum was 12,092 individuals. The sum of the site-level 5 -year means was 15,428 individuals during the same period. The sum of national wintering population estimates from TR, RO and BG was 8,057-13,128 indiivduals (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Delany &¬†Scott (2006) have considered the earlier population too low and increased in based on BirdLife International (2004), but it is unclear how did they derive the current estimate.
  • T6560 - The population in RO is increasing while it is stable in BG (European Topic Centre on Biological Diversity, in prep.).
  • S9067 - The IWC count totals were around 15,000 - 60,000 individuals during 2011-2015 (Wetlands International 2017), i.e. the maximum count has reached the population estimate Delany &¬†Scott (2006) derived from the breeding population estimate for RU in BirdLife International (2004), despite the fact that countries with important populations of the species, such as UA, were not counted during this period. The sum of the national wintering population estimates is 16,000 - 45,000 individuals (BirdLife International 2015).
  • T6967 - IWC trends are uncertain but show positive tendency both for the long- and the short-term (Wetlands International 2017). This agrees with the wintering and breeding trends reported by BirdLife International (2015) for the region.
