Dark phase Ross's Goose (which is extremely rare) has a different plumage pattern than this bird, a pattern more like Blue Goose, with black and white pattern on neck and head - see Sibley field guide for example.

Nick - for my knowledge, could you define a little further what separates these from full Ross's Goose? I haven't seen many, so further information would be very helpful.

My first thought was that it was a blue morph Snow Goose, but the proportions seem off. Could this be a blue morph Ross's Goose? Or maybe a hybrid of some sort? Its body is very dark.
