Notes

  • T5424 - Wetlands International 2012. Trend 1991-2007: -2.6% p.a. ? Significant long-term decline. However, most data being from only one country, Iran.
  • T2333 - 898. Trend 1991-2007: -2.6% p.a. – Significant long-term decline. However, most data being from only one country, Iran.
  • T6486 - Significant long-term decline.
  • S8908 - See CSR7 and Sheldon (2017).
  • T6813 - Stable both in the short- and the long-term (Wetlands International 2017). The trend graph shows increase up to the late 1990s, followed by a rapid decline in the early 2000s and stabilisation in the last decade.
  • S9357 - The size of the breeding population is estimated at 7,750-14,870 pairs, or 23,000-45,000 individuals after rounding in AZ (BirdLife International, in prep.), TM, KZ, UZ (Kalyakin et al., 2020) based on data from the period of 1996-2019. The highest annual IWC count total between 2014–2018 was 8,181 individuals (Nagy & Langendoen, 2020). The breeding range in IR is small. Therefore, a new population estimate of 23,000-50,000 is proposed.
  • T7454 - The population is thought to have increased in AZ (BirdLife International, in prep.) and it was stable in TM. The trend is uncertain in KZ (Kalyakin et al., 2020). Based on IWC data from nine countries, Nagy & Langendoen (2020) reported uncertain trends for the periods of 2003-2017 (0.9725) and 2008-2017 (1.0083). based on the growth rate of the overall trend, the population is projected to decrease by 38% in 17 years, i.e. in 3 generations.
