Notes

  • S8410 - 40,000-115,000 pairs on Greenland and Iceland (BirdLife International, 2004), tens of thousands in N Canada (Cramp & Simmons, 1983).
  • T6409 - No update on trends yet.
  • S8963 - 40,000-115,000 pairs on Greenland and Iceland (BirdLife International, 2015), 50,000-100,000 breeding birds in Canada (Canadian Wildlife Service 2015). Petersen et al. (2014) estimated the whole population at 34,400-114,400 pairs including all birds from CD and the later estimate is adopted here.
  • T7037 - Thought to be stable in GL. 30-50% decline in IS (BirdLife International 2015). Moderate decline in Canada (Canadian Wildlife Service 2015). Petersen et al. (2014) largely agrees with this although they suggest that the population might be even increasing in GL and cast some doubts on the declining trend in CD based on interviews with Inuit hunters, but note that these claims are not confirmed by aerial surveys. Considering the uncertainties involved with the population size estimate for GL and the magnitude of decline in CD, it is not possible to define the trend more precisely.
