Goose hybrid

@ bealburton,thanls for the link.
Never new so many hybrids existed , Liam suggested
Chinese x Embden hybrid (also domesticated Swan x Greylag Goose).

I'd love to be able to give you a better species identification, but the best I could do was find another picture listed as a hybrid (half-domestic/half-Canada). It's about half-way down the link, has the same essential coloring, plus orange legs and black bill.
