Notes

  • S2250 - 22,500- 38,700 pairs (67,500-116,100 individuals) in S Norway & Sweden belong to this form (Hario in press 2006). These + summed data from other relevant countries (BirdLife International (2004b)) result in estimate of 108,560-146,323 pairs (325,680-438,969 individuals).
  • S8417 - 188,599-233,084 pairs in BE, DE, DK, NL, NO, SE (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.).
  • T6416 - 2000-2012: 1.0095-1.0262, 1980-2012: 1.0218-1.0334 (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Increasing in all countries of its breeding range except NO and SE where it is decreasing.
  • S8971 - 188,599-233,084 pairs in BE, DE, DK, NL, NO, SE.
  • S9482 - The size of the breeding population is estimated at 185,656-204,156 pairs, or 560,000-610,000 individuals after rounding in NO, BE, DE, DK, NL, SE based on data from the period of 2013-2018. Mixes and intergrade with L. f. graellsii. Estimates are calculated based on country allocations in the absence of subspecies-level estimates. Country allocations follow the reporting in under Article 12 of the EU Birds Directive for 2008-2012 and include some L. f. graellsii in NL, DE and DK (Olsen, 2010).
  • T7626 - Based on BirdLife International (in prep.), it is estimated that the breeding population has changed by -5-12% in BE, DE, DK, NL, SE between 2009 and 2018. No quantitative trend information is available from NO. In the long-term, it has increased in all range states but NO where it has decreased by 10-25%. As with population size, the trend cannot be legitimately assessed for this population through mid-winter counts.
