Notes

  • T5357 - Wetlands International 2012. Trend 1992-2007: +1% p.a. - Uncertain.
  • T2193 - Wetlands International 2012. Trend 1992-2007: +1% p.a. – Uncertain.
  • T6477 - Long-term trend is fluctuating, but the short-term one indicates large decrease.
  • T6835 - Stable/fluctuating in the long-term. This overall trend confounds large long-term fluctuation.
  • S9360 - The size of the breeding population is estimated at 3,718-21,923 pairs, or 11,000-66,000 individuals after rounding in GE, AM, AZ (BirdLife International, in prep.), TM, KZ, UZ (Kalyakin et al., 2020) based on data from the period of 1996-2019. However, no breeding population estimates are available from IR and IQ where sizable population may occur.
  • T7461 - No quantitative national population estimates are available. It is thought to be decreasing in AZ, stable in AM (BirdLife International, in prep.) and TM. Unknown elsewhere. Based on IWC data from 7 countries, Nagy & Langendoen (2020) reported decreasing trends for both 1994-2017 and 2003-2017, while the population has stabilized at a lower level in 2008-2017. Based on the smoothed imputed totals, the population has decreased by 66% (p < 0.05) in 14 years, i.e. in 3 generations.
