Any idea if this is a muscovy duckling?

Showed up in a friend's backyard all by himself in Ft. Myers, Florida. Trying to make sure it isn't some protected species that needs to go to a wildlife rehabber asap. Muscovies are invasive down here, and he looks like he might have the bigger bump on his nose.

This is just my opinion, but his face doesn't look quite right for a muscovy. The beak looks a little long and not as snubby. Could you get a picture of him dry?
