To me it appears to be a green anole that a cat or something has messed w/. he's brown cause he's cold. a brown (bahamian or cuban) when brown would have a pattern of a sort, and a stubbier head.
Even in FL there aren't to many of them anymore. The invasive browns which are much more aggressive have basically taken over. 20 years ago I used to see more green ones, like 20-30% greens to browns. Now you see browns everywhere, and maybe one to two greens. In my back yard I have two males. One adult and juvi. In the side yard there is one or two more greens that live in the little palm tree. THERE ARE BROWN ANOLES EVERYWHERE. I also don't ever see green tree frogs in my yard. The HUGE cuban tree frogs have taken over. I have a big Cuban tree frog that resides in one of my sheds. Like clock work he comes out and perches on a tree branch above the shed every evening to hunt after dark. I have seen green tree frogs at a jobsite north of me about an hour from Tampa.
