LOL--Great picture, but I was referring to a picture of the beak, closeup.
We had geese for quite a while. They are VERY territorial, and will attack. I pulled feathers every year...the goose will grab on with its beak, and twist, while beating with the very strong wings--I used to put a sock or glove over their heads and tuck it under my arm, before pulling feathers, still got bit and beat on.
