Description of the Bird

The large white-headed bird was in the middle of a large flock of Canada geese feeding. All were feeding on the mowed lawn not far from the lake's edge. At first I thought the bird was a mixed-breed of a Canada Goose but then saw it was distinctly larger than the very large flock of geese around it. Also it had a pinkish beak that was very bold in color and distinctly different from the Canada Goose beak. i am familiar with Snow Geese and this bird had a white head and long white neck ,but not a white body, Also a bluish tint to the rest of the body. When i looked up the enlarged photo (one of many I took of the whole flock)  I took when I got home it matched  every aspect of the "Blue Goose" relative of the Snow Goose. I have been a birdwatcher for 40 years and never seen one before.
