Nice pics. They look like squirrel tree frogs but they are easiest to identify in the green color phase. The green tree frog is a good possibility but the brown, and mixed brown and green, coloration is relatively uncommon. Both species are common in the mid Florida area.
Thanks for all the nice comments. These are Cuban tree frogs. Their color ranges from pale bone to the brown leopard cammi design. They sound like little birds chirping.
