ID help on a goose sp., Larimer

[Joe Kipper]

Hey Birders,

I photographed this goose at Lake Loveland in Larimer County that is very interesting.

My ebird checklist has the photos and my thoughts about the bird's ancestry.

I would appreciate any feedback on what others think about this goose, and even if it not identifiable, I thought I would share the photos just so others can enjoy this beautiful bird!

I'm no geneticist, but Sibley says that all manner of color gradients exist in Blue Snow Goose.  And this bird clearly has the dainty bill of a Ross.'  Suggesting Snow x Ross' hybrid.
