Notes

  • S2749 - Summed breeding populations of relevant countries 33,775-37,808 pairs (101,325-113,424 individuals) (64) less 1,000-2,000 pairs (3,000-6,000 individuals) in Volga Delta. Overall total: 98,325-107,424.
  • S8446 - 46,595-75,215 pairs in BG, BY, GR, HU, LT, LV, PL, RO, RU, SK, TR, UA (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Further 3,705-4,730 pairs in AL, HR, GE, MK, MD and RS&ME (BirdLife International, 2004). This yields a total estimate of 150,000-240,000 individuals after rounding.
  • T6444 - Stable/fluctuating in the short-term, increased in the long one (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.).
  • S8994 - 53,040-86,299 pairs.
  • T7076 - Increased both in the long- and the short-term.
