What kind of geese are these ?

[Coulter]

What is a white fronted goose? One simple answer...the specklebelly goose. It is named for the patch of white feathers bordering the base of its bill. But even more distinctive are the salt-and-pepper markings on the breast of adult birds, which is why the goose is colloquially called the "specklebelly" in North America. They are more grey than white, other than patch of white around the bill.

I wouldn't be too concerned with a state or federal officer questioning you on those geese. They are clearly domestic. If they were snows or ross, then you may have some issues if the season isn't open for them yet.
