Tree frogs: Masters of camouflage

The gray tree frog is a small frog native to the eastern U.S. and parts of southeastern Canada. An adult can grow to a length of nearly three inches. This frog has the sense to climb high into trees where it is safe from most predators. It prefers to cling to the vertical sides of things such as trees, houses and fence posts rather than spend time on the ground.

The gray tree frog can camouflage itself, and if sitting long enough on a moss-covered tree trunk it will turn more green than gray. If found hiding on the side of a tree, it will often be hard to distinguish from the tree bark. Small insects make up this frog's diet.

Although not slimy, if held in your hand this little guy will seem cool to the touch and will cling easily to your finger. In Southeast Missouri where there are trees, bushes and a stream or pond for tadpoles to raise, there will likely be gray tree frogs.

The one I have photographed here was on the side of an old shed. As I slowly got closer and closer, with the camera lens maybe two inches from his face, he suddenly alerted as if seeing his reflection in the glass. I snapped the picture and he leapt into a nearby bush.
