Notes

  • S2247 - Earlier estimates included intermedius in The Netherlands and Spain in this population. 64: Summed data from relevant countries: 176,705-187,740 pairs (530,115 - 563,220 individuals).
  • S8416 - 178,382-192,079 pairs in EU breeding range countries, GL and IS (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.) and further 9,000 pairs in FO (BirdLife International, 2004). This yields a total estimate of 146,382-148,579 pairs, i.e. 562,000-603,000 individuals after rounding.
  • T6415 - 2000-2012: 0.9630-0.9724, 1980-2012: 1.0081-1.0104 (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Earlier increase has apparently turned into decline. However, short term decline is only reported from the UK and ES.
  • S8970 - 186,382-198,877 pairs. Data from FO is from 1981.
  • T7044 - Long-term trend is still increasing.
