A medium-sixed toad with a light gray, tan, brown, or greenish-gray ground color with paired dark markings on the back. Each dark spot on the back may encircle 1–6 “warts.” There is often a thin white stripe down the back. The belly is cream-colored, and there may be a dark gray spot on the chest. The oblong parotoid gland is connected to a rather shallow bony crest on the head. Makes a short, nasal “w-a-a-a-h,” lasting from 1 to 2½ seconds.
Similar species: Fowler’s toad used to be considered a subspecies of Woodhouse’s toad, but breeding call studies showed the breeding calls are quite distinct. It occurs in different parts of the state, usually lacks a chest spot, and its oblong parotoid gland is connected to a rather prominent bony crest on the head. Fowler’s toad probably hybridizes with the eastern American toad. Where this happens, intermediate characteristics will occur.
