Our Froggy is a Cuban Tree Frog and they can change colors quickly from a light grey to a dark brown. Not native to Florida they are here to stay now and well established up through the central portion of the state.
Back in 2003 when my 2 small ponds were created to breakup the backyard and provide primarily a water garden for lilies it didn’t take long for these tree frogs to move in. In the evening if you are wondering where they might be, all you have to do is imitate their call and they will answer letting you know right where they are.
The Heron is sneaky :o)
