Bird-Voiced Treefrog
Hyla avivoca from South Carolina. These treefrogs do not range far from the Savannah River in SC. They are superficially similar in appearance to Cope's Gray Treefrogs (H. chrysoscelis), who will sometimes be found calling in close proximity to these frogs. The Bird-Voiced Treefrog is smaller and is limited to oxbows and swamps along the river floodplain. They can often be heard calling, which sounds somewhat like a squeaky wheel, high atop the cypress trees surrounding bodies of water.
