GREAT PLAINS TOAD Anaxyrus cognatus,
The adult Great Plains toad averages 4.8-9 cm in length. On its back it has large dark blotches. Each blotch is boldly bordered by light pigment and contains many warts. The colors of this toad are generally yellowish, brown, greenish, or gray on top. Below is unspotted, cream to white, with a yellow or orange-yellow seat patch. Some specimens have been found with a narrow, light mid dorsal stripe. The head of the Great Plains toad is relatively small with a well-developed cranial crest. Their snout is blunt and rounded.
Found throughout western Kansas to the east edge of the Flint Hills. But also follows the riparian corridor along the Kansas River and then along the Missouri River to the North. Specimens from southern Douglas and northwest Miami counties are each over 50 years old and in need of verification.

Breeding April to September, usually during or after heavy rainfall. Egg strings are attached to debris on bottom of pool.
The Great Plains Toad call is a high pitched, long mechanical trill resembling the burst of a machine gun. A breeding chorus can be heard for up to two kilometers across the prairies.
Primarily nocturnal, but sometimes found foraging on cloudy, rainy days. This frog prefers loose soil where burrowing is easy. When in danger, it inflates, closes it eyes, and lowers its head to the ground.
It is a voracious predator of cutworms, which cause extensive crop damage.
Predators and Defense:
Toads have enlarged glands (called the paratoid glands) on the side of the neck, one behind each eye. These glands secrete a viscous white poison that gets smeared in the mouth of any would-be predator, inflaming the mouth and throat and causing nausea, irregular heart beat, and, in extreme cases, death. Toads pose a danger to pets, which may pounce on and bite them. Humans should take care to wash their hands after handling a toad, and to avoid touching the mouth or eyes until having done so.
