Notes

  • T4195 - Wetlands International 2012. Trend 1983-2007: +5.7% p.a. ? Increase. However, trend in African portion of range poorly known.
  • T855 - 898. Trend 1983-2007: +5.7% p.a. – Increase. However, trend in African portion of range poorly known.
  • S8590 - 193,418 individuals at the wintering areas in the 2010s. Rounded and raised to 200,000
  • T6583 - Trend analyses based on mid-winter count indicate large increase both in the short- and long-term, i.e. 1979-2014 and 2003-2014 respectively, (van Roomen et al 2014, Nagy et al 2014) . The trend in both the European part and African part of the range is increasing (van Roomen et al. 2014).
  • S9036 - 193,418 individuals at the wintering areas in the 2010s. Rounded and raised to 200,000 (van Roomen et al. 2015). The European breeding population is estimated at 25,100-50,100 pairs (BirdLife International 2015), which agrees rather well with the estimate based on wintering numbers considering that some of the birds breeding on Taymir also partly allocated to this population.
  • T7139 - After strong increase, the population seems to have stabilised.
