Notes

  • S5645 - Estimate for the wintering population in coastal W Greenland: 100,000 (80).
  • S8561 - The two Palearctic populations are separated based on their breeding grounds and their wintering areas overlap. 12,000-33,000 breeding pairs are estimaetd on GL and IS (BirdLife International et al., in prep.). Wintering numbers in GL, IS, IE and the UK are estimates to be 163,000-1,200,000 individuals, both much higher than the upper limit of the estimate of 99,000 individuals calculated from the estimated breeding population. However, the wintering estimate for GL ranges between 100,000 and 1,000,000 (Merkel et al., 2002), but birds may winter around GL both from West Sibera and Canada.
  • T6554 - Likely increasing based on spring counts from Lake Myvatn (R. Hearn in litt, 2014).
  • S9055 - The two Palearctic populations are separated based on their breeding grounds and their wintering areas overlap. 12,000-33,000 breeding pairs are estimaetd on GL and IS (BirdLife International 2015). Wintering numbers in GL, IS, IE and the UK are estimates to be 163,000-1,200,000 individuals, both much higher than the upper limit of the estimate of 99,000 individuals calculated from the estimated breeding population. However, the wintering estimate for GL ranges between 100,000 and 1,000,000 (Merkel et al., 2002) and birds wintering around GL might come from both from West Sibera and Canada.
