Distribution
Eastern and central Oklahoma. A common toad throughout much of the state, it is usually found hunting for insects at night in populated areas, especially near bright light sources that attract nocturnal insects. They can be heard calling from spring pools after rains. Their call is a high pitched trilled whistle. Very difficult to distinguish from the Woodhouse's Toad (Bufo [Anaxyrus] woodhousii), the American toad tends to have only 1-2 warts per dark spot and a spotted belly, whereas the Woodhouse's toad tends to have 3 or moer warts per dark spot and a plain, but darkened belly. Both have large, bean-shaped parotoid plands slightly separated from the cranial crest, and both may have light lines running down the middle of the back.
