Although known as cackling geese the subspecies you probbably got is really known as a Richardson's goose. One of the cackling subspecies. About the same size as a Ross's goose(white). Little bit larger than a mallard unless young of the year. Somewhat pointed bill with a fairly sharp nail on the end. The only cackler that really seems to go that far east. Shot a few over the years. You have a really neat bird and if possible you should have it mounted. You just don't see that many in the east and it is somewhat unique. Congrats
BTW if you can... post a pic
