I captured this image last month at Ocracoke Island on the Outer Banks. I could be wrong, but it appears this species is a hybrid....the body was like that of the Canada Goose but with a much shorter brownish neck and white patches around the bill and face.I believe this may be a hybrid of a Canada goose and greater white-fronted goose.
This image was taken on a partly cloudy day with the sun in at the time and needed to add exp comp as checked with histogram. I know the whites at top of bill are a little hot and will need to see if I can recover some of those highlights there. Most of my images of this bird were not great but thought I would share this one.

A nice portrait, Lori. You may be right about the ID as these two species are known to hybridize. Canada geese can sometimes have unusual white patches here and there on the face and neck, but they would not have the short neck that you describe.
