I think this is a Greylag Goose. Despite the white forehead and the slightly soiled bill, this goose has a structure that looks very Greylag with thick neck, huge deep bill and bulky head. There are also actually some white mantle barring slightly obscured by lighting. Perhaps just a Greylag with some weird features?
