Swan?

These are not great pictures, I'm just wondering if anyone here can tell me what bird this is. He was hanging out in the stream behind out house. My daughter yelled just as I was about to snap the picture, so I was a couple seconds too late for the first and he was quite far away when he landed in the second. He looks like a Mute Swan and if so we're supposed to report them to the DNR.

Thanks. I feel silly. :redface: I showed the picture to a friend who said she thought it was a Mute Swan. He bill looks rather short in the first photo which is why I wasn't sure.
