Notes

  • T4731 - Wetlands International 2012. Trend 1988-2006: +6.2% p.a. ? Increase.
  • T484 - 898. Trend 1988-2006: +6.2% p.a. – Increase.
  • S8293 - The average IWC count total was 516,191 individuals during the period of 2008-2012. The sum of the site-level 5-year means was 1.421,369 individuals during the same period. The peak count was 1,538,658 in 2007. Considering that important parts of the region were not counted, the estimate of 2,000,000 birds for this population (Perennou et al. 1994) appears to be still valid.
  • T6293 - IWC data shows large increase until 2007 followed by a large decrease (Nagy et al., 2014). However, IWC coverage is sparse in the region and weather related shifts and variable counting effort can highly distort the results.
  • T7089 - Stable long-term trend. This confounds that the earlier increasing population trend has turned into a steep decline from 2006.
  • S9305 - The breeding population size at 501,370-940,920 pairs, or 1,500,000-2,800,000 individuals after rounding in AM, AZ (BirdLife International, in prep.), TM, KZ, UZ and West Siberia (Kalyakin et al., 2020). The size of the wintering population is estimated at 560,000-760,000 individuals in AM, AZ (BirdLife International, in prep.), UZ (Kalyakin et al., 2020), but no wintering estimates reported from other range states. The highest annual IWC count total between 2014–2018 was 516,664 individuals in 2016 (Nagy & Langendoen, 2020). This is much lower than the maximum count of over 1,500,000 birds counted in 2007 mainly in IR.
  • T7394 - The breeding population is considered decreasing in AZ, increasing in AM (BirdLife International, in prep.), stable in KZ and fluctuating in TM and West Siberia (Kalyakin et al., 2020). Based on IWC data, Nagy & Langendoen (2020) reported decreasing trends for 2003-2017: 0.8907 and for 2008-2017: 0.8638. Based on the growth rate of the overall trend, the population is projected to decrease by 90% 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 87% in 3 generations compared to the population levels in 2008.
