Notes

  • T5727 - Fox et al. 2010. Trend 1995-2009: +6.8% p.a.
  • T2697 - 876. Trend 1995-2009: +6.8% p.a.
  • S8258 - Minimum estimate based on IWC Count totals in 2009 (61,848) and 2011 (59,284 individuals).
  • T6259 - Trend 1988-2012: +5.66% p.a., 2003-2012: +1.19%.
  • S8882 - 14,304 - 20,094 pairs (i.e. 43,000 - 60,000 individuals) in AL, AT, BY, CH, CZ, EE, FI, HR, HU, IT, LT, LV, PL, SK. This tallies well with the previous estimate based on IWC counts in 2009-2012. However, count totals reached 70,000 birds in 2013. Fox & Leafloor (in prep) produced an index based estimate of 100,000 individuals, but this might be an overestimate.
  • T7167 - Trend 1988-2012: +5.66% p.a., 2003-2012: +1.19% (Nagy et al. 2014). Fox & Leafloor (in prep). estimated +6.8% for 1995-2008.
  • S9178 - BirdLife International (in prep.) estimated the breeding population size at 18,663 - 32,489 pairs, or 68,000 - 118,000 individuals after rounding and using a special conversion factor of 3.63 (Johnson, 2020) in AT, BA, BY, CH, CZ, EE, FI, HR, HU, IT, LT, LV, PL, RS, SI, SK, AL. The wintering population size is estimated at 66,000 - 160,000 individuals after rounding in AT, BA, BY, CH, CZ, HR, HU, IT, ME, PL, RS, SI, SK based on the same source. No estimates are available from TN, but numbers are small there according to the IWC data. The highest annual IWC count total between 2014–2018 was 136,337 individuals (Nagy & Langendoen, 2020), which still represents a minimum population estimate considering the possibility of significant numbers not being counted during the IWC.
  • T7260 - Based on BirdLife International (in prep.) it is estimated that the breeding population has increased by 25-79% in AT, BA, BY, CH, CZ, EE, FI, HU, IT, LT, LV, PL, RS, SI, SK between 2009 and 2018. Based on the same source, it is estimated that the wintering population has increased by 14-54% in AT, BY, CH, CZ, HU, IT, PL, RS, SI, SK between 2009 and 2018. Based on the IWC data, the population has increased by around 4.5% annually (Nagy & Langendoen, 2020) in each of the overall, the 3-generation and 10-year trend periods, which is equivalent to 53% increase between 2009 and 2018.
