Color ranges from green, greenish gray, gray, tannish gray to brown. Often has a white or tan stripe down the back. There are irregular (not paired) dark brown or black spots on the back with 1–6 “warts” inside each spot. The belly is plain white, but sometimes with a single “breast” spot. Call is a short, nasal “w-a-a-ah,” lasting from 1 to 2 1/2 seconds, similar to the call of the Fowler’s toad, but with a slightly lower pitch.
