The map does not depict
the actual range of the
Eastern Gray Treefrog in
1-1/4" - 2" (3.2 - 5.1 cm) Rough skin, green to gray to brown, light spot beneath eye, bright yellow or orange on concealed surfaces of hind legs, large toe pads, a rough or bumpy dorsal skin, usually with darker blotches. Indistinguishable physically from Cope's gray treefrog. Can only be distinguished in the field by their calls.
Call is a short high trill, a little more musical than the Cope's Gray Treefrog, and slower. Trill pulse rate for the versicolor is said to vary from 17-35 pulses/second.
