Notes

  • T6551 - Increased in Franc Joseph Land (M. Gavrilo in litt. 2014)
  • S9060 - 20,000-27,500 pairs (BirdLife International 2015). The Norwegian Polar Institute (2017) reports 13,500-27,500 pairs on Svalbard. The current abundance of the common eider on Novaya Zemlya is unknown (Krasnov et al. 2016).
  • T7169 - Increased in Franc Joseph Land (M. Gavrilo in litt. 2014). The Norwegian Polar Institute (2017) reported data that indicates a a 2% p annum rate of decline for the period of 2007-2016, with a majjor crash in 2013 and 2016. The long-term trend (1982-2016) is a 0.6% p.a. decline, which can be interpreted as stable but would be equivalent to 34% decline over 7.5 generations. However, this is based on only one location even if that represents 15-22% of the estimated Svalbard breeding population. The trend quality is assessed as being poor because the trend is assumed based on partial information.
