Population justification: Although the global population was previously estimated to be 35,000 individuals, recent counts indicate that it is considerably higher, with perhaps > 89,000 individuals in total (Lei and Barter in litt 2007). The majority of birds spend the non-breeding season in China, (c.78,000 individuals), Japan (c.9,000 individuals), North Korea and South Korea (c.2,000 individuals) (Wetlands International 2002; Lei and Barter in litt. 2007).

Trend justification: The species appears to be declining in southern China, remaining common only in Dongting Hu, Hunan Province (S. Chan in litt. 2005) and there have been notable declines at least locally in the breeding range, for instance, on Lake Udyl the total number of Falcated Duck broods has fallen from 530 to 120 broods since the 1980s (Poyarkov 2006). Populations in Japan and Korea appear to have remained stable or declined only slightly (S. Chan in litt. 2005). Overall, the population is suspected to be undergoing a moderately rapid decline.
