Cope's Grey Treefrog

Description:

The Cope's Grey Tree Frog (Hyla chrysoscelis) is a species of tree frog which is found in the United States. It is almost indistinguishable from the Grey Tree Frog, Hyla versicolor, and shares much of its geographic range. Both species are variable in color, mottled gray to gray-green, resembling the bark of trees. These are tree frogs of woodland habitats, though they will sometimes travel into more open areas to reach a breeding pond. The only readily noticeable difference between the two species is the call—Cope's has a faster paced, and slightly higher pitched, call than H. versicolor. In addition, H. chrysoscelis is reported to be slightly smaller, more aboreal, and more tolerant of dry conditions than H. versicolor (Martof et al., 1980). The range of H. chrysoscelis is more southerly—it is apparently the species found in the lower elevation Piedmont and Coastal Plain of Virginia and the Carolinas. In those areas, H. versicolor may be present only in the Appalachians (Martof et al. 1980). The Bird-voiced Tree Frog, Hyla avivoca, is similar to Hyla chrysoscelis/versicolor, but is smaller (25–50 mm length, vs. 32–62 mm for the Grey Tree Frogs).[Source: Wikipedia]
