Cope's Gray Treefrog Hyla chrysoscelis

Description: 1 - 2 inches. Although the name may imply that it is always gray, Cope's Gray Treefrogs can actually change color from gray to green, tan, or brown. The back may have a random pattern of darker color. The inside of the thigh is yellowish in color, and the toes have large pads on the end that allow them to climb many surfaces.

Similar Species: Eastern Gray Treefrogs are identical in appearance but can be distinguished by their lower, more melodic call.

Comments: Absent from northeastern Minnesota.
