These little guys were quite prevalent at the place we stayed in Orlando, Florida, and made for a fun photo op.
I believe they are Brown Anoles, a non-native species of lizard that was brought into the country from the Caribbean as pets and now have a range across Florida into Georgia.
In the mornings and evenings they would be scurrying about making you watch where you stepped. This particular one, had a favorite tree where it would move around, bob its head, then extend its dewlap. They never sat still for long and were pretty wary so it was a challenge to get decent pics of them.
