Notes

  • S2132 - 75% of Larus canus breeding in Russia (BirdLife International (2004b)) estimated to be heinei: 562,500 - 2,250,000. West Siberian population unknown but likely to be at least as large as that in European Russia.
  • S8406 - New estimates for European RU (75%) is 187,500-450,000 pairs, i.e. 562,000-1,350,000 individuals (Mischenko, 2004). Size of the Asian part of the population is unknown.
  • S8958 - New estimates for European RU (75%) is 187,500-450,000 pairs, i.e. 562,000-1,350,000 individuals (Mischenko, 2004). Size of the Asian part of the population is unknown.
  • T7031 - Stable trend is assumed for the breeding population in European RU (BirdLife International 2015). The IWC trend analysis indicate an increase (Wetlands International 2017).
  • S9479 - 487,500-637,500 pairs in European RU (75%), 20-150 pairs in UA (BirdLife International, 2015). 250,000-500,000 pairs in West Siberia and 3,100-15,500 in KZ (Kalyakin et al., 2020).
  • T7622 - In the breeding season, the short-term trend is unknown. Between 1980 and 2018, the population has increased by 10-500% in UA, where it has a marginal breeding population, but unknown elsewhere (BirdLife International, in prep., Kalyakin et al., 2020). Based on IWC data from 21 countries, Nagy & Langendoen (2020) reported uncertain trends for 1993-2018 (0.9945) and for 2009-2018 (0.9773). Based on the growth rate of the overall trend, the population is projected to decrease by 16% in 32 years, i.e. in 3 generations. Based on the growth rate of the last 10 years, the population is projected to decrease by 52% in 3 generations compared to the population levels in 2009. However, this population mixes with the L. c. canus, NW & C Europe/Atlantic coast & Mediterranean population in part of its wintering range (Olsen, 2010).
