  • S8146 - Skov et al. 2011. 1,480,000 in Baltic Sea 2007-2009. Over 90% of this population occurred in the Baltic in the 1990s and this implies a 65% decline since the last comprehensive survey assuming a similar current distribution.

  • S5649 - 899. 1,480,000 in Baltic Sea 2007-2009. Over 90% of this population occurred in the Baltic in the 1990s and this implies a 65% decline since the last comprehensive survey assuming a similar current distribution.
  • T3748 - 899. 1,480,000 in Baltic Sea 2007-2009. Over 90% of this population occurred in the Baltic in the 1990s and this implies a 65% decline since the last comprehensive survey assuming a similar current distribution. Four sources (889, 890, 891, 892) indicate a collapse of 70% in the population wintering around Sweden, Finland and Estonia between 1995 and 2010.
  • S8207 - Skov et al. (2011) estimated the number of Long-tailed ducks at 1.486,000 individuals in the Baltic Sea based on surveys and modelling in 2007-2009. The total of the national estimates in the wintering range is 1,238,490-2,287,117 individuals, but this includes the entire UK wintering population (11,000 birds), but does not include some 80,000-120,000 birds wintering off Norway (BirdLife International, 2004). In addition, adding up the national minimum and maximum estimates usually generates a broader estimate than an annual count total and less accurate.
  • T6212 - Additional evidence is reviewed by Aunis et al (2013) and Musgrove (2011).
  • S9056 - Skov et al. (2011) estimated the number of Long-tailed ducks at 1.486,000 individuals in the Baltic Sea based on surveys and modelling in 2007-2009. BirdLife International (2015) has estimated the European wintering population to be around 1,300,000 - 2,600,000 individuals without Greenland, Iceland and the UK. Their breeding population estimate for Scandinavia and European Russia is 325,900 - 411,800 pairs (i.e. 978,000 - 1,235,000 individuals), but this does not include birds breeding in West Siberia. Considering the uncertainties and gaps in summing up the national estimates, the AEWA SSAP (Hearn et al. 2015) for the species has retained the current estimate until the results of the coordinated Baltic Seaduck Survey of January 2016 are available.
  • T7168 - Hearn et al. (2015) have reviewed available evidence of decline. IWC-based trend analyses (HELCOM 2017, Wetlands International 2017) suggest that some recovery is taking place since the mid-2000s, but the JWGBIRD (Markones in litt) expressed doubts concerning the representativity of land-based counts and reassessment of the trend is pending until the availabilty of the 2016 January Coordinated Baltic Seaduck Survey.
