The bill is smaller than on a Snow Goose which I think comes from part Ross's. Also, the base of the bill is almost straight like a Ross's instead of an arc like a Snow.

Yesterday, 24 March, I photographed an interesting white goose at Prince Lake #2. It was roughly the size of nearby Canada Geese, too big for a Ross's Goose. The bill was too large for Ross's and did not have the perfectly straight vertical base of a Ross's. The head was not perfectly round like a Ross's. The bill appeared too small for a Canada Goose and did not have a significant grin patch. In summary, the head features were intermediate between Ross's and Snow. I conclude that this is a Ross's Goose x Snow Goose hybrid. See attached photo.--
