The Swan Goose (Anser cygnoides) is a large bird with a long bill and neck. It has a brown cap and lightish underparts. Males are somewhat larger than females. They are the parent source of some domesticated breeds, particularly the Chinese Goose. There are estimated to be a world population of 60,000 birds.
It breeds in southern Russia, Mongolia and northern China, and winters in the Yangtze basin, China.
Birdlife International has recently adjusted their status from Endangered to Vulnerable based on “This species has been downlisted to Vulnerable because despite poor breeding success in recent years owing to drought, and considerable pressure from habitat loss, particularly owing to agricultural development, and unsustainable levels of hunting, comprehensive surveys in the wintering range have failed to detect evidence of declines of the magnitude predicted.”
