Notes

  • S8492 - New estimate for EU Member States is 3,072-6,577 pairs (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Complementary estimates for other countries from BirdLife International (2004) is 7,810-11,410. Thus the European population is estimated at 9,682-16,387 pairs, i.e. 32,600-54,000 individuals. In addition, over 600 breeding pairs in Egypt (Dodman, 2014).
  • T6487 - Based on partially updated data, the population's growth rate was 2000-2012: -2.48 - + 2.54% p.a., 1980-2012: -0.83 - 0.79% (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). However, the RU and TR populations declined during 1990-2000 (BirdLife International, 2004) and, if continued, the overall trend can be declining. Therefore, the population is classified as one being in significant long-term decline.
  • S8849 - 9,219-16,569 pairs in AL, BA, BG, CY, GE, GR, HR, HU, MD, ME, MK, RO, RS, RU, SK, TR & UA (BirdLife International 2015). In addition, over 600 breeding pairs in Egypt (Dodman, 2014).
  • T6826 - Declining both in the long- and the short-term.
