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 estimated 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 Siberia 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 estimated 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 Siberia and Canada.
  • S9193 - The two Palearctic populations are separated based on their breeding grounds and their wintering areas overlap. BirdLife International (in prep.) provided the same estimate, 12,000-33,000 breeding pairs in GL and IS as in 2015 (BirdLife International 2015). However, the estimated wintering numbers in GL, IS, IE are much smaller: 92,000-210,000 individuals in GL, IE, IS, i.e. without GB with a population estimate of 13,371 birds. The GB population was reallocated to the Western Siberia/North Europe (bre) based on the available limited ringing evidence. The difference in wintering numbers is mainly because the estimate for GL was revised to 40,000 individuals from 100,000 - 1,000,000 individuals.
  • T7273 - Based on the breeding trend.
