Notes

  • S2641 - BirdLife International (2004b) estimate from relevant countries 21,211-37,486 pairs (63,633-112,458 individuals).
  • S8443 - 301-779 pairs in RO, BG, and CY (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Further 20,983-36,240 pairs in GR, UA, RU, TR, AL, BY, MK, RS, ME (BirdLife International, 2004), IL and EG (Fasola et al., 2003). According to Dodman (2014) 3,800 pairs in EG.
  • T6440 - Decreasing in BG, increasing in CY, unknown in RO (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Declined in AL, RU, TR, increased in RO (but now unknown) and was stable in other countries. Trend is also unknown in EG and IL.
  • S8990 - 22,788-35,175 pairs in Europe (BirdLife International 2015). According to Dodman (2014) 3,800 pairs in EG.
  • T7073 - Declining both in the short- and the long-term, but at a slower rate than the threshold for significant long-term decline.
  • S9494 - The size of the breeding population is estimated at 19,400-28,030 pairs, or 58,000-84,000 individuals after rounding in AL, BA, BG, BY, CY, GE, GR, ME, MK, RO, RS, RU, TR, UA (BirdLife International, in prep.), EG (Habib, 2016) based on data from the period of 2007-2019.
  • T7638 - Based on BirdLife International (in prep.), it is estimated that the breeding population has changed by -13-4% in BA, BY, CY, GR, RS, AL between 2009 and 2018. No quantitative trend information is available from BG, GE, ME, MK, RO, RU (representing majority of the population), TR, UA, EG. However, it was stable in most countries and declined only in AL and BA in this period. It has decreased by 12-19% in BG, BY, CY, GR, RS, RU, AL between 1980 and 2018. No quantitative trend information is available from BA, GE, ME, MK, RO, TR, UA, EG. Based on IWC data mainly from ZA, Nagy & Langendoen (2020) reported strong decrease for 1993-2015 (0.8647) and for 2006-2015 (0.6996). However, this only represents the extreme south end of the wintering range and might be not representative for the whole population.
