Rightful owner of the river

Taken from the bridge today on our way to Tesco , we watched this swan attack rowers oars, much to our amusement , rowers complain about the swans, there was talk of culling one particularly vicious one, because of course rowers own the river, its not a natural habit for swans *rolls eyes* they will ban fish soon aswell i expect , imagine ! fish in a river ! :O
