Burlington Free Press: Middlebury’s Jim Andrews on the gray treefrog

Gray treefrog gets second billing: “Jim Andrews, a herpetologist at Middlebury College, says it is a rare student who can pick out a gray treefrog on a tree when the frog is not calling. Gray treefrogs are masters of disguise. Their bumpy, gray, patterned skin makes them look like a clump of lichen on the bark of a tree. Further, their skin changes color from white to green to dark gray, allowing them to blend in to their surroundings even better. (Yes, gray treefrogs can be green.)”
