I was taking a picture of the bird with his wings spread and when I got home and looked at it, lo and behold there is at least one alligator, maybe two. You need to click and enlarge this one to see all the wildlife.
There was a nice lady sitting on a bench with her two little dogs watching all the "ducks". She corrected me and I am so grateful - this is a "Coot".
And there was no one around to tell me about these guys who were swimming and, I assume, eating dinner in the green algae.
