Another Goose Puzzle - UK (1 Viewer)

This white Goose has been swimming about on the local wildfowl reserve since last winter and was possible there the winter before. This is the first time I've seen it out of the water. Both Canada and Greylag Geese are abundant and have plenty of goslings. Looks too big to be a Greylag, similar in size to a Canada but body seems bulkier. Canada Geese in second photo for comparison.

Thanks

Pat

It is a domestic greylag goose x Canada goose hybrid. Those can turn out white and blue-eyed too.

The bill is much too small for a domestic greylag, and the tail feathers are uniform greyish to the tip, no hint of the pattern of Anser geese there.
 
I've seen a goose looking nearly identical to this one, which after a long search i identified as a Canada x white domestic (Greylag) hybrid. Domestic/Greylag x Canada hybrids vary considerably in colour depending on how far the domestic parent is from wild Greylag colouring, and can be very varied even within one brood. They are all intermediate in general proportions between Canada and Greylag though, and tend to have a more Canada-like head and bill shape.

The goose in question (which only ever accompanied Canada geese, and lived on a park boating lake with no resident domestic/Greylag geese): http://pic.atpic.com/1622020/600
