I travelled North and was lucky to get good views of the swan from just North of Ledges Park. I parked at the pull in and walked to the path down at the riverside. This gave direct views to the swan across the river.
My overriding view was this bird was too big to be close to a Tundra Swan. Overall size was Trumpeter like with long neck and heavy look. Naive I maybe but this was nothing like a Tundra/Bewicks Swan. Big guy all the way!
