What are the attributes cause you to think it’s part Ross’s goose? Thanks for the thoughts on that.

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.
