s. It prefers grassland habitat with loose soil that is easy to burrow in. Breeding occurs throughout the spring and summer months, most often immediately after heavy rainfall. In dry areas it may only emerge from its burrow for a few weeks when conditions are right, and usually at night, but in areas with permanent water bodies and abundant rain it may be active all day. Its mating call is a very loud, harsh chirping noise repeated many times really fast.
The toad is predated by the Plains Garter Snake
