Common Names: Gray tree frog, eastern gray treefrog, common gray treefrog, tetraploid gray treefrog
A species of small arboreal frog native to much of the eastern United States. The Gray tree frog is capable of surviving temperatures as low as -8 degrees Celsius.
Gray tree frogs are highly variable in color owing to their ability to camouflage themselves from gray to green, depending on the substrate they are sitting on. The degree of mottling varies. They can change from nearly black to nearly white. They are relatively small compared to other North American frog species, typically attaining no more than 1.5 to 2 inches. Their skin has a lumpy texture to it, giving them a warty appearance. They have bright yellow patches on the hind legs, which distinguishes them from other tree frogs.
The gray tree frog is most common in forested areas, as it is highly arboreal. Their calls are often heard in rural residential areas of the east coast.
