Notes

  • S8573 - 7,000-10,000 pairs in the entire European RU (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.) and 384 in UA (BirdLife International, 2004). This yields 22,000-31,000 individuals. Possible some of this birds winter NW & C Europe or the Caspian. The average IWC count total was 509 individuals between 2008 and 2012. The sum of the site-level 5-year mean was 1,070 individuals during the above mentioned period.
  • T6566 - The breeding population in RU is though to be decreasing, but wintering populations are stable in CY and GR, decreasing in BG, fluctuating in RO and unknown in TR, RU and UA (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.).
