Comments: From Bird Hybrids: Swan Goose x Canada Goose: “Many domestic geese contain a mix of Swan Goose and Greylag Goose genes and when such mixed-species domestic geese hybridise with Canada Geese the offspring may resemble either Swan Goose x Canada Goose hybrids or Greylag Goose x Canada Goose hybrids – sometimes both in a single brood.”

Domestic Swan Geese, often referred to as Chinese Goose, have a knob at the base of the upper mandible that is lacking in wild birds. Chinese Geese are common in captivity and as feral birds in park-like settings.
