Snow Goose, is what you have. About 2/3 of their numbers are actually Bluish, called Blue Goose. Most of them come out of the Eastern parts of uppper upper Canada. As they migrate they spread across the entirety of the US, so they can be seen everywhere down here. Possible if it was ealier, it was headed North, because most of the time they don't stay here in the warm months like Canadian Geese do.
