I have seen two pairs of ones that look just like the Greylag pictures on the net and they are right in with the Canadas over at our Fairgrounds. They have a very blocky build and look like a darn domestic goose, so maybe they are. Their honk is exactly like a domestic and nothing like the Canadas and they can fly, but not as easily as our Canadas that are much more streamlined for flight..
