Notes

  • S3720 - 437 estimate 45,000-99,460 pairs (135,000-298,300 individuals). Russian population poorly known.
  • S8488 - Breeding population in PL, AT, SK, HU, SI, RO, BG at 1,815-3,287 pairs (European Topic Centre on Biological Diversity, in prep.). In addition, based on BirdLife International (2004) we can assume another 19.855-31.360 pairs in CZ, HR, BA, AL, MK, GR, UA, RU, TR, GE, AM, AZ and RU. Kushlan and Hancock (2005) estimated the whole Eurasian population at 105,000 pairs. If this is correct, the current maximum estimate for this population seems unrealistic, considering that some 46,000 pairs are accounted for in Europeand several tens of thousands must be also present in East, South East and South Asia. Therefore a lower estimate of 135,000-180,000 individuals seem to be more realistic.
  • T6483 - Apparently stable in HU, the small population in SK is declining by 20-40%. Fluctuating in RO, BG and SI (European Topic Centre on Biological Diversity, in prep.), but no recent trend information from other countries with larger populations.
  • T6819 - According to the IWC trend analysis data, the population is possibly in significant long-term decline although only partial information is available (Wetlands International 2017)
