Bird-voiced Treefrog (Hyla avivoca)

The bird-voiced treefrog is usually a mottled gray, but like many treefrogs, its dorsal coloration may change to brownish or green with temperature or activity. This frog is easily mistaken for the larger gray treefrog, which is very similar in coloration, including a light square below the eye. The bird-voiced treefrog is most easily distinguished from its look-alike by the greenish yellow flash colors on the concealed portion of its hind leg, which are usually more orange in color in the gray treefrog. Bird-voiced treefrogs inhabit wooded swamplands of the South, where they can be heard calling during spring and summer.
