Notes

  • S8283 - In 27 European countries that reported to the Birds Directive Art. 12 reporting and for the European Red List of Birds, the breeding population in these countries in 197,426-410,096 pairs (European Topic Centre on Biological Diversity, in prep., BirdLife International, et al., in prep.). In the countries that not reported yet, there could be an additional 95,681-208,404 pairs according to BirdLife International (2004). In addition, there are an estimated 1-1.5 million pairs in RU. A further 515,000-1,240,000 pairs are estimated for Asiatic Russia (Schäffer and Mammen 1999), yielding 5,000,000-10,000,000 individuals as new population estimate.
  • T6283 - Whilst some of these populations may be increasing, population trends are unclear and often show large fluctuations (K. Koffijberg in litt. 2007) in response to changes in agricultural practices or annual rainfall (A. Mischenko in litt. 2006).
  • S8997 - 1,294,132-2,120,311 "pairs" in Europe (BirdLife International 2015). A further 515,000-1,240,000 pairs are estimated for Asiatic Russia (Schäffer and Mammen 1999).
  • S8998 - 1,294,132-2,120,311 calling males in Europe (BirdLife International 2015). A further 515,000-1,240,000 calling males are estimated for Asiatic Russia (Schäffer and Mammen 1999).
  • T7080 - The European population is stable both in the short- and the long-term.
  • S9293 - The breeding population is estimated at 1,619,483-2,635,276 pairs, or 4,900,000-7,900,000 individuals after rounding in AL, AM, AT, AZ, BA, BE, BG, BY, CH, CZ, DE, DK, EE, FI, FR, GE, GR, HR, HU, IE, IT, LI, LT, LU, LV, MD, ME, MK, NL, NO, PL, RO, RS, RU, SE, SI, SK, TR, GB, XK (BirdLife International, in prep), KZ and West Siberia (Kalyakin et al., 2020).
  • T7382 - It is estimated that the breeding population has decreased by 10-21% in AM, AT, BA, BE, BG, BY, CH, DE, EE, FI, FR, HR, IE, IT, LT, LU, LV, NL, PL, RO, RS, RU, SE, SI, SK, GB, AL (BirdLife International, in prep.) and KZ (Kalyakin et al., 2020) between 2009 and 2018. No quantitative trend information is available from AZ, CZ, DK, GE, HU, MD, ME, MK, NO, TR, XK. The trend is also unknown in West Siberia (Kalyakin et al., 2020). Based on the same sources, it is estimated that the breeding population has changed by -29-14% in AT, BA, BE, BG, BY, CH, DE, EE, FI, FR, GE, IE, IT, LT, LU, LV, NL, RS, RU, SE, SI, SK, GB, AL and KZ between 1980 and 2018. No quantitative trend information is available from AM, AZ, CZ, DK, HR, HU, MD, ME, MK, NO, PL, RO, TR, XK. No long-term trend is available from West Siberia (Kalyakin et al., 2020).
