Notes

  • S2242 - Earlier estimates included intermedius in Denmark, S Norway & Sweden in this population. 296: National surveys, including total survey of Finland in 2004, resulted in estimate of 18,000-19,000 pairs (54,000-57,000 individuals) for nominate fuscus and confirmed predominance of intermedius in Norway & Sweden.
  • T5094 - Hario and Nuutinen 2011. Survey in Scandinavia in 2005 provided basis for accurate separation from intermedius and together with monitoring data from the Finnish coast revealed the small size and rapidly decreasing status of the population of nominate fus
  • T1475 - 903. Survey in Scandinavia in 2005 provided basis for accurate separation from intermedius and together with monitoring data from the Finnish coast revealed the small size and rapidly decreasing status of the population of nominate fuscus. National Red Data books of Finland, Sweden, Norway and Estonia and a 2011 paper in Oris Fennica (46) describe the ‚Äúdrastic decline‚ÄĚ and suggest the principal cause is breeding failure related to organochlorine pollution.
  • S8415 - 17,812-26,838 pairs, i.e. 53,000-81,000 inidividuals (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.)
  • T6414 - 2000-2012: 0.9621-1.009, 1980-2012: 0.9701-0.9904 (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Decline continues in EE (55-70%), FI (15-48%) and NO (unquantified), but stopped in SE. Unknown in RU.
  • S8969 - 17,812-26,838 pairs.
  • T7043 - Significant long-term decline
