This big fella accounts for 3 of the 4 options in this section - it was in France, he would have come from an escape and he's non-indigenous.
It appears to be a Coypu - they have them in that area apparently. It's a small pond in the Northern half of France and a little Yorkshire terrier was in the only set of bushes that go up to the water's edge. I thought that she was after the Moorhen and its baby that were there, but suddenly we saw a head in the middle of the pond, and she had chased it out. I pan across to show the reason for the Coypu's swim :)
There are also a couple of stills which I will post.
