- S8451 - 300-380 pairs, i.e. 900-1,140 post-breeding individuals, in AM, RU and TR (BirdLife International, 2004). However, the formerly 200-250 pairs-strong population in TR now counts only 100-150 pairs (Boyla, in litt). 55-2,114 individuals winter in BG, RO and CY (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Further 5,260-21,210 wintering individuals are estimated in AL, AZ, GR, TR and UA (BirdLife International, 2004). The average IWC count total was 2,158 individuals during the period of 2008-2012. The sum of the site-level 5-year mean was 3,821 individuals during the same period. There was a high count of 9,622 in 2003 and another one with 8,199 individuals in 2006 (Wetlands International, unpublished data). A. Green (in litt, 2014) reported an observation of 4,000 individuals at Arin Gulu on 20 October 2014.
- T6449 - Data incompletely updated. According to the European Topic Centre on Biological Diversity (in prep.) data the wintering numbers have decreased in BG and RO even in the 2000s. However, there is very little updated trend information from the rest of the range, but see notes under population size.
- S9052 - Revised estimate is based on numbers recorded in Kazakhstan (18,049-20,859 individuals).
- S9165 - Revised estimate is based on numbers recorded in Kazakhstan (18,049-20,859 individuals) on moulting sites (Sheldon, 2017). This tallies well with the 16,950 individuals observed along the Caspian coast in Turkmenistan in January 2019 (Toni Eskelin, in litt). The population size is revised according to Sheldon et al. (2018).
- T7246 - The IWC population trend is uncertain but indicates a declining population in each trend period (Nagy & Langendoen, 2020). However, IWC count data is mostly available from the Eastern Mediterranean and site coverage is less consistent in the eastern part of the range. In the absence of consistent site coverage, it is difficult to ascertain if the observed decline is real or just a redistribution of the population. Although counts have decreased in AZ, IR and TR, they have increased in IL and large numbers were discovered in TM. In the short-term, large declines in the wintering populations in BG, GR and RO, but the population is considered stable in CY, AL, AZ and UA while unknown in GE and RS. The breeding population in European RU has decreased by 20-29% between 2008 and 2018 and also decreased in TR while it is considered fluctuating in AM (BirdLife International, in prep.), increasing in KZ and UZ, uncertain in West Siberia and unknown in TM (Kalyakin et al., 2020). However, other experts have reported a stable population for RU (Sheldon et al., 2018) and the same source also reports stable populations in AM and SY. The long-term national trends are also assessed similarly, but it is well documented that the population has suffered large historic declines (Scott & Rose, 1996).
