Notes

  • S3892 - 437 & 283 estimate 30,700-45,900 pairs (92,100-137,700 individuals).
  • T5662 - BirdLife International 2004b. Increased in Turkey and Serbia, declines in Slovenia, Bosnia-Herzegovina and Albania, stable in other countries between 1990 and 2000. The breeding population also declined in Greece during the same period (Yfantis and Kazant
  • T2441 - 64. Increased in Turkey and Serbia, declines in Slovenia, Bosnia-Herzegovina and Albania, stable in other countries between 1990 and 2000. Depleted.
  • S8494 - New estimates for BG, CY, CZ, HU, PL, RO, SI, SK, which adds up to 10,156-16,930 pairs (European Topic Centre on Biological Diversity, in prep.). Breeding population estimates for AL, BY, BA, HR, GR, MK, MD, RU, RS, ME, TR and UA add up to 29,589-42,242 pairs (BirdLife International, 2004). Together this suggests a population of 39,745-59,172 pairs, i.e. 119,000-178,000 individuals. In addition, less than 1000 birds in Egypt (Dodman, 2014).
  • T6489 - The overall trend of populations in BG, CY, CZ, HU, PL, RO, SI, SK is apparently stable both in the short (2000-2012) and long-term (1980-2012, European Topic Centre on Biological Diversity, in prep.). Although updated trend information is not yet available for the majority of the population, during the 1990-2000 period the trend was stable or increasing in all countries except HR, BA and AL (BirdLife International, 2004).
  • S8853 - 43,042 - 67,952 pairs in AL, AT, AZ, BA, BG, BY, GE, HR, HU, MD, ME, MK, PL, RO, RS, RU, SI, SK, TR, UA& XK (BirdLife International 2015). In addition, less than 1000 birds in Egypt (Dodman, 2014).
