The Swan Goose breeds in Russia, Mongolia and mainland China. It winters in North Korea, South Korea, central China, and occasionally in Japan and Taiwan (China). While being part of the goose family, it exhibits some swan-like characteristics such as the male "knob" on the forehead. They pair in winter and are long-term monogamous. The Swan Goose is listed as "Vulnerable " with 60,000-90,000 individuals left. Substantial declines have been observed in the population of this species in parts of its breeding range in eastern Russia and Mongolia, as well as its wintering areas in China. The global population is suspected to have decreased rapidly, in line with levels of hunting and wetland conversion for agriculture and development, with both of these threats operating on the breeding and wintering grounds. It is legally protected in Russia, Mongolia and South Korea and some provinces in China. Several important sites are protected in Russia, Mongolia and China.
