Notes

  • S2312 - 64: European breeding population 37,000-56,000 pairs (111,000-168,000 individuals). 198: About 11,000 pairs in North Africa (mainly Egypt & Tunisia).
  • T1511 - 914. Increasing W Mediterranean, stable or possibly decreasing East Mediterranean/Black Sea.
  • S8422 - 35,604-44.960 pairs in European countries (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). 4,225 nests in EG (Dodman, 2014), 3,000-4,000 pairs in TN, 12-24 pairs in MA, possible breeds in DZ (BWPi, 2006). This yields an estimate of 133,000-200,000 inidividuals estimate.
  • T6421 - 2000-2012: 09838-0.9956, 1980-2012: 0.9871-0.9993 (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). The decrease is the large populations of UA and TR, but it is increasing in RU, GR and IT, fluctuating in FR and stable in BG and ES.
  • S8974 - 35,604-57,035 pairs in Europe (BirdLife International 2015). 4,225 nests in EG (Dodman, 2014), 3,000-4,000 pairs in TN, 12-24 pairs in MA, possible breeds in DZ (BWPi, 2006).
  • T7052 - Trends based on both breeding and wintering seasons indicate decline in the short-term. Assessment of the long-term trend differs.
