The map does not depict
the actual range of the
Cope's Gray Treefrog in
1-1/4" - 2" (3.2 - 5.1 cm) Rough skin, green to brown, light spot beneath eye, bright yellow or orange on concealed surfaces of hind legs, large toe pads on tips of fingers and toes for climbing vegetation. Few differences exist between this species and the Eastern gray treefrog. Cope's tends to be smaller, has smoother skin. Indistinguishable physically in the field from gray treefrog. Can only be distinguished in the field by their calls.
Call is a short raspy trill on one pitch. Call is similar to Hyla versicolor but the pulse rate is faster (34-69 pulses/sec).
