The only tree frogs of "typical" size in the area, the Common and Cope's Gray Tree Frogs are usually 3-5 cm in length and have rough, moist skin. They range in color from gray to green and look virtually identical, but have distinctly different calls. The Common Gray Tree Frog has a low, fluttery call with slower trill rates than the Cope’s, which has a faster, harsher call. The call of the Cope’s is similar to that of the American Toad, but is higher pitched and given in faster one second blasts at intervals of 2 to 5 seconds.
When breeding in the spring and early summer, males usually call from forest wetlands or in nearby vegetation. At times, one or two males can be heard in chorus making a high pitched chirp. This call is given when one male has infringed upon the territory of another. Outside of breeding season, gray tree frogs also call intermittently from the forest throughout the summer, especially during and immediately after rain.  The Tree Frog can be found in leaf litter, under loose bark, in the cavities of old trees, in woodpiles, in birdhouses, or around wetland plants.
