help Swan goose FAQ
Where does the swan goose breed and where does it spend winter?
The wild swan goose, Anser cygnoides, breeds in inland Mongolia, northeastern China, and the Russian Far East. It migrates mainly to central and eastern China for winter, using lakes, rivers, estuaries, and nearby grasslands.

Wild swan goose populations face wetland loss, hunting, and egg collection, and the species is listed as Endangered on the IUCN Red List. Its natural range is in East Asia, even though domesticated forms are common elsewhere.
