Notes

  • T477 - 700: Populations wintering in Baltic and NW Europe estimated to be decreasing marginally in both long and medium term. Central European population stable.
  • T4729 - Wetlands International 2012. Trend 1983-2007: -0.1% p.a. ? Stable.
  • T480 - 898. Trend 1983-2007: -0.1% p.a. – Stable.
  • S8291 - The average IWC count total was 974,496 individuals for the period of 2008-2012. The sum of the site-level 5-year means was 1,162,567 during the same period. the maximum count was 1,121,321 individuals in 2005. The national estimates of wintering birds add up to 1,483,281-1,642,924 individuals, while of breeding birds 368,735-604,341 individuals in BE, DE, DK, EE, ES, FI, FR IE, LT, LU, LV, NL, SE, UK, PL (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Further 25,008-49,015 in NO, CZ, LI, CH (BirdLife International, 2004). This yields an estimate of 1,200,000-2,000,000 post-breeding individuals.
  • T6291 - The IWC trend shows a moderate increase in the long-term, but a large decrease in the short one (Nagy et al., 2014). The trend derived from national estimates for wintering and breeding birds show a slightly different pattern. There, the decrease is moderate but statistically significant also in the long-term (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Trends based on wintering data: 1980-2012: 0.9954-0.9997, 2000-2012: 0.9810-0.9995, trends based on breeding numbers: 1980-2012: 0.9800-0.9849, 2000-2012: 0.9643-0.99 (BirdLife International 2004). However, EBCC et al. (2012) suggests that the population has increased during the period of 1980-2012.
  • S9003 - 388,993-662,601 pairs in AT, BE, CH, CZ, DE, DK, EE, FI, FR, IE, LI, LT, LU, LV, NL, NO, PL, SE & UK (BirdLife International 2015). The IWC count totals were between 775,000 and 945,000 during the period of 2011 and 2015 (Wetlands International 2017).
  • T7164 - Stable both in the short- and the long-term (Wetlands International 2017). However, BirdLife International (2015) suggests decline in the breeding numbers both in the short- and the long-term.
  • S9303 - BirdLife International (in prep.) estimated the breeding population size at 408,314-644,099 pairs or 1,200,000-1,900,000 individuals after rounding in AT, BE, CH, CZ, DE, DK, EE, FI, FR, IE, LI, LT, LU, LV, NL, NO, PL, SE, GB. They estimated the wintering population size at 1,400,000-1,500,000 individuals in AT, BE, BY, CH, CZ, DE, DK, EE, FI, FR (80%), IE, LI, LT, LU, LV, NL, PL, SE, GB. The highest annual IWC count total between 2014–2018 was 992,291 individuals in 2016.
  • T7392 - Based on BirdLife International (in prep.), it is estimated that the breeding population has changed by -12-7% in AT, BE, CH, CZ, DE, DK, EE, FI, IE, LT, LU, NL, PL, SE, GB between 2009 and 2018. No quantitative trend information is available from FR, LV, NO. It is estimated based on the same source that the breeding population has decreased by 74-46% in AT, BE, CH, CZ, DE, DK, EE, FI, LT, LU, LV, NL, PL, SE, GB between 1980 and 2018. No quantitative trend information is available from FR, IE, NO. Based on BirdLife International (in prep.), it is estimated that the wintering population has changed by -9-0% in AT, BE, BY, CH, CZ, DE, DK, EE, FI, FR, IE, LV, NL, PL, SE, GB between 2009 and 2018. No quantitative trend information is available from LI, LT, LU. Based on BirdLife International (in prep.), it is estimated that the wintering population has decreased by 3-17% in AT, BE, CH, CZ, DE, FI, FR, LU, LV, NL, SE, GB between 1980 and 2018. No quantitative trend information is available from BY, DK, EE, IE, LI, LT, PL. Based on breeding bird data from the Pan-European Common Bird Monitoring Scheme, Nagy et al. (2020) reported a slight increase (1.0045) for the period of 1984-2017 a decrease for the periods of 2005-2017 (i.e. 3 generations: 0.9863) and 2008-2017 (0.9870). Based on the PECBMS data, this population has declined by 9-20% over 3 generations. Based on IWC data from 17 countries, Nagy & Langendoen (2020) reported a moderate decrease for each of the periods of 1968-2018 (0.9987), 2002-2018 (0.9843) and 2009-2018 (0.9822). Based on the smoothed imputed totals, the population has decreased by 19% (p < 0.05) in 16 years, i.e. in 3 generations. Based on the growth rate of the last 10 years, the population is projected to decrease by 22% in 3 generations compared to the population levels in 2009. HELCOM (2018) also reports a moderate decline (0.9678) for the Baltic subpopulation. Wing survey data in DK does not show any significant decline in reproductive success (Christensen, 2020). However, this might not be representative for the whole flyway. It is important to note that most of the growth rates are rather close to each other and probably the results of the formal monitoring schemes carry more weight than the aggregation of national trend estimates.
