Notes

  • S3380 - 64: Breeding population in relevant countries (including 50% of pairs in European Russia) 119,000-149,000 pairs (357,000-447,000 individuals).
  • T5285 - Wetlands International 2012. Trend 1993-2007: +1.8% p.a. ? Increase.
  • T2077 - 898. Trend 1993-2007: +1.8% p.a. – Increase.
  • S8470 - Bregnballe et al. (2014). Alternative estimate based on data from European Topic Centre on Biological Diversity (in prep.) and BirdLife International et al. (in prep.) and complemented with data from Birdlife International (2004) for countries with missing data resulted in a higher estimate of 686,000-948,000 individuals.
  • T6468 - Data from European Topic Centre on Biological Diversity (in prep.) and BirdLife International et al. (in prep.) suggest an increase of 0.27-1.09% p.a. for breeding birds during the period of 2000-2012, and moderate increase of 0.23-0.56% p.a. for the period of 1980-2012. IWC trend analysis of wintering birds (Nagy et al. (2014) suggests large increase (+3.77±0.94% p.a.) trend for the period of 2003-2012 and a rapid increase (+2.79±0.39% p.a.) for the period of 1992-2012. These data contradicts the large decline reported by Bregnballe et al. 2014 for the period of 2006-2012 based on two set of colony counts.
  • S8838 - Bregnballe et al. (2014).
  • T6802 - Wetlands International (2017) reported stable short-term trend based on the IWC data. This agrees with the short-term trend reported by BirdLife International (2015).
