Nice image, it does look like a swan impression. However I don't like Blue Herons. They eat the Koi out of my garden pond. I think they wade rather than swim because I have been told that the best defense is to put up a fishing line barrier because they walk in rather than fly in. They feel the line and turn away.
I've only seen one swimming once or twice. They definitely fly in, then wade around.
