Notes

  • S5373 - 64 estimate European breeding population at 390,000-590,000 pairs (1,170,000-1,770,000 individuals). 656 suggests a West African wintering population of 1,500,000 - 2,000,000. 98 estimated 640,000-1,100,000 pairs (1,920,000-3,300,000 individuals) for entire population.
  • S8063 - Trolliet et al. 2007. 1,505,000 counted in simultaneous aerial counts of W African Sahel, Jan 2006.
  • T6070 - Trolliet, B. In litt. 2011. Suggests that the population is stable.
  • T3541 - 920. Suggests that the population is stable.
  • S5376 - 882. 1,505,000 counted in simultaneous aerial counts of W African Sahel, Jan 2006.
  • S8538 - The previous population estimate of 2,000,000 individuals was set by Scott & Rose (1996) based on wintering counts and total of European breeding populations in (Tur cke& Heath, 1994). This estimate was retained based on mid-winter counts of 1,505,000 individuals from synchronised aerial count in the Senegal Delta, Inner Niger Delta and Lake Chad Basin in 2007 (Trolliet et al., 2008) that does not include birds from other parts of West Africa. Updated breeding population estimates account for 328,148-485,314 pairs in UK, ES, FR, BE, LU, NL, DK, SE, FI, EE, LV, LT, PL, DE, CH, IT, SK, HU, SI, RO, BG, BY, RU, TR, CY, GR (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Further 23,321-36,620 pairs in the countries without updated breeding population estimates, i.e. UA, MD, BA, SR&ME, MK, AL, GE (BirdLife International, 2004). This yields a total estimate of 351,749-522,314 pairs, i.e. 1,000,000-1,600,000 individuals after rounding, but it does not include birds from West Siberia, which might be in the range of 100,000 individuals. However, it agrees well with the 1,000,000-1,500,000 estimates by Zwarts et al. (2009). An allowance of 100,000-200,000 individuals was made for birds in Burkina Faso, Benin, E Senegal, W Mali, Central African Republic not covered by the aerial surveys of the great lakes in the Sahel.
  • T6534 - The trend calculated based on IWC data is uncertain or fluctuating (Nagy et al., 2014) that agrees well with the results of the dedicated surveys on the wintering grounds (Triplet et al., 2010; Trolliet et al., 2008). This agrees also with the latest trend estimates (2000-2012: 0.9809-1.0168, 1980-2012: 0.9978-1.0001) for breeding birds (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Based on this dataset, breeding numbers decrease in the UK, BE, NL, FI, LT, SK, HU, BY, GR, increase in DK, stable or fluctuating in ES, LU, SE, EE, DE, CH, SI, BG, CY and unknown in FR, LV, PL, IT, RO, RU and TR as well as in the countries with no updated data.
  • T6939 - Long-term (1971-2015): strongly fluctuating with an overall stable trend.
