Several Green Anoles were observed in the Texas Discovery Gardens exhibit at the State Fair of Texas.

Wikipedia has this to say about Green Anoles:

Anoles also display curiosity. A healthy lizard usually has a good awareness of its surroundings. The male is very territorial and will fight other males to defend its territory. The other male is frequently an introduced and invasive brown anole (Anolis sagrei). When browns first immigrated to the United States in the early 1970s, the Carolinas ceded their ground-level territories and were relegated to a very different ecosystem high in the treetops. On occasion a more aggressive Carolina may be seen closer to the ground and in competition with the browns.
