  • S8463 - Max. count was 20,106 in 2004 and up to 5,000 individuals are also in PK (Li et al., 2009) and several thousands may winter in the Gulf as proven by 2,500 beached birds during the Gulf War in 1990/1991 (Jennings, 2010).
  • T6461 - Annual count totals have decreased rapidly since 2004 and this was also refelcted in totals accounting for missing values. However, counts are mostly from Iran.
  • S8902 - See CSR6 and Sheldon (2017).
  • T6792 - The population is in significant long-term decline according to Wetlands International (2017).
