Notes

  • S8956 - The new estimate retained the estimate of van Roomen et al. (2014) that is based on wintering numbers and estimated the maximum value based on the European breeding numbers of 7,150-15,780 pairs (BirdLife International 2015) with some allowances for the breeding pairs in Central Asia.
  • T7029 - BirdLife International (2015) reported that the populations in RU and TR are declining. This contradicts the results of the mid-winter counts that report stable/fluctuating trend (van Rooment et al. 2014, Wetlands International 2015)
