Population justification: The most recent total population estimate is 24,000-40,000 individuals, which compares with previous published global estimates of 25,000 to 30,000 individuals (Lorentsen et al. 1999) and 22,000 to 27,000 (Delany and Scott 2006). This includes 10,000-21,000 individuals in autumn in its Western Palearctic range (Jones et al. 2008, Fox et al. 2010) and 14,000-19,000 individuals from the East Asian Flyway (Jia et al. 2016, C. Lei per A. Fox in litt. 2016). In 1988-1993, 64,000 individuals were recorded (Jia et al. 2016); in 1997, the number declined to 20,000 individuals (Li and Mundkur 2004), and to less than 17,000 individuals (Morozov and Syroechkovski 2005): 16,937 birds were counted in the Lower Yangtze Valley in 2004 (Barter et al. 2004), and 16,600 in East Dongting Lake Nature Reserve in 2004 (Barter 2005). The Russian populations have declined from a former estimate of 30,000-50,000 individuals (Morozov 1995). The Fennoscandian population has declined from more than 10,000 birds in the early 20th century.
Trend justification: This species's population is suspected to have decreased rapidly, owing to high levels of hunting on the staging and wintering grounds and habitat deterioration, largely as a result of land cultivation. The decrease in numbers has been accompanied by fragmentation of the breeding range and is continuing to affect all populations. Modelling indicates that 28% of the habitat for this species could be lost by 2070 (Zöckler and Lysenko 2000).
