Notes

  • T4833 - Delany et al. 2009. Stable in Iceland, decrease in the Faeroes and increasing in Scotland.
  • T634 - Delany et al. 2009. Stable in Iceland, decrease in the Faroes and increasing in Scotland.
  • S8309 - Thorup (2006) estimated the population size to be 250,000 pairs, which was maintained as the current estimate to the European Red List of Birds (BirdLife International et al., in prep.). T. Gunnarsson (in litt., 2014) suggested that 200,000 pairs is a safe estimate. However, winter counts account for only 131,865 phaeopus and islandicus combined (van Roomen et al., 2014).
  • T6309 - Trend information is only available from the UK which supports a very small part of the population (European Topic Centre on Biological Diversity, in prep.).
  • S9020 - Thorup (2006) estimated the population size to be 250,000 pairs, which was maintained as the current estimate in the European Red List of Birds (BirdLife International et al., in prep.). T. Gunnarsson (in litt., 2014) suggested that 200,000 pairs is a safe estimate. However, winter counts account for only 131,865 phaeopus and islandicus combined (van Roomen et al., 2014).
  • T7192 - Trend information for breeding numbers is only available from the UK which supports a very small part of the population (BirdLife International 2015). The wintering population mixed with phaeopus is increasing (van Roomen et al. 2015) but the two populations cannot be separated. In the past, the population was thought to be stable (Delany et al. 2009) therefore it is not considered to be in significant long-term decline.
  • S9404 - The size of the breeding population is estimated at 258,320 pairs, or 770,000-780,000 individuals after rounding in FO, GL, IS, GB based on data from the period of 2009-2018.
  • T7535 - The population has decreased by 35% in GB between 1991 and 2009 and by 30% between 1982 and 2009. Trends are unknown elsewhere (BirdLife International, in prep.). In winter, it is mixed with the 'phaeopus, Northern Europe/West Africa' population that is about 30% of the combined wintering population. The combined population is increasing (van Roomen et al. 2018). In the past, the population was thought to be stable (Delany et al. 2009) therefore it is not considered to be in significant long-term decline.
