- 4 1/2 in
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.
