8 Types of Toads Found in Kansas! (ID Guide)
“Don’t pick that up, you’ll get warts!”
If you’re anything like me, you heard this quite a few times growing up from a parent telling you to leave a toad alone. With their bumpy skin, staring eyes, and loud, insect-like calls, it’s understandable to be cautious around toads. But luckily, it’s a myth that toads give people warts!
Today, you will learn about the different kinds of toads in Kansas.
A note on this list: Some of the species below are considered spadefoots, which are not technically toads. Spadefoots are a separate group of frogs that are closely related to toads. Because they are similar in so many ways, I am including them here. If you see a spadefoot, you may not even realize it’s not a true toad! I will outline the differences between toads and spadefoots later in the article.
#1. American Toad
- Anaxyrus americanus
Identifying Characteristics:
- Adult length is 2-3 ½ inches.
- Coloring is usually brown to gray, olive, or brick red. Typically, they have patches of yellow, buff, or other light colors, with dark spots.
- The American Toad is distinctive for its many warts present all over the back and legs.
American Toads can be spotted easily in eastern Kansas.
You can find both subspecies of the American Toad here: The Eastern and Dwarf.

It is one of the most common and widely known species of toad! They live in forests, prairies, and suburban backyards. American Toads are carnivorous and mainly eat insects, worms, spiders, and slugs.
American Toads have a very recognizable call. Listen for a musical trilling noise that can last for up to 30 seconds.
They like to breed in shallow water, and tadpoles have an amazing defense against predators. Their skin secretes a toxic chemical so powerful that eating one American Toad tadpole can kill a fish!
Much like their tadpoles, adult American Toads are also toxic to other animals. Even large dogs that handle or try to eat one can have discomfort or pain from contact with their milky-white secretions. This is something my dog found out the first (and last) time he played with one!
#2. Great Plains Toad
- Anaxyrus cognatus
Identifying Characteristics:
- Adult length is 2-4 ½ inches.
- Coloring is pale white to tan or olive with large, dark-colored pairs of blotches down the back. Lighter tan or white belly.
- A crest on the head forms a “V” shape from the snout, moving outward on the head toward the back.
Great Plains Toads are found in Kansas living in temporary shallow pools, quiet streams, marshes, or irrigation ditches. They are most common in grasslands but also can be found in desert brush and woodland areas.
Great Plains Toad Rangemap:
There are only a few weeks out of the year that are suitable for the Great Plains Toad to feed and reproduce. Amazingly, they spend the rest of the year mostly dormant in underground burrows made by other animals.
Symmetrical dark splotches running down its back make the Great Plains Toad one of the easier toads to see, but you will probably hear one nearby long before you can spot it. Its call can last more than 50 seconds, and is similar to a jackhammer!
When large groups of Great Plains Toads are calling, the sound can be near-deafening.
#3. North American Green Toad
- Anaxyrus debilis
Identifying Characteristics:
- Adult length is 1-2 inches.
- The coloring of the North American Green Toad is bright green to yellow-green, with black markings that sometimes connect to form a web-like pattern. Black-tipped warts are also common.
- On females, the throat is pale yellow to white. On males, the throat is black or dusky brown.
In western Kansas, the North American Green Toad lives in very dry climates and can only be spotted during heavy rains. It tends to prefer clear land with few trees.

The North American Green Toad goes by ten different names, depending on its location!
You may know it as the Sonora Toad, Dwarf Toad, Green Toad, Little Green Toad, Chihuahuan Green Toad, Eastern Chihuahuan Green Toad, Little Green Toad, Eastern Green Toad, Western Chihuahuan Green Toad, or the Western Green Toad. Wow, what a mouthful!
Their calls are short and cricket-like, lasting up to 7 seconds with about the same time in between.
To reproduce, North American Green Toads travel to temporary water sources like drainage ditches, rain-fed streams, and small pools. Males attract females to breeding areas by singing in chorus.
#4. Red-Spotted Toad
- Anaxyrus punctatus
Identifying Characteristics:
- Adult Length is 1.5 – 3 inches.
- The coloring of the Red-Spotted Toad is light gray, olive, or red-brown, with distinctive red or orange warts. The belly is white or buff.
- Red-orange warts are numerous and cover the entire top of the body including legs and feet.
The Red-Spotted Toad is very recognizable in southwestern Kansas.
Just look for the many red or orange warts set against the pale coloring of the rest of its skin! They can be hard to find though because they are mostly nocturnal, spending their days in rock crevices or underneath plant debris.

Red-Spotted Toads can survive losing up to 40% of the water in their bodies!
They commonly live around rocky outcroppings with temporary water from rain-fed streams or underground springs.
The call of a Red-Spotted Toad is a high-pitched trilling that lasts about 10 seconds.
#5. Woodhouse’s Toad
- Anaxyrus woodhousii
Identifying Characteristics:
- Adult length is 2 ½-4 inches.
- Coloring ranges from gray to yellowish or olive green.
- The belly is light tan or buff with very few dark spots located on the chest.
Woodhouse’s Toads are adaptable to many environments in Kansas, including grasslands, deserts, floodplains, and developed areas. Interestingly, individuals that live in suburban areas will wait under street lamps to catch and eat insects attracted to the light.
Woodhouse’s Toad Rangemap:
The most striking feature of Woodhouse’s toads is their shape – they are very round and stout, with short legs that look too small to support their bodies!
Woodhouse’s Toads have a very short call that resembles a distressed sheep’s bleat.
SPADEFOOTS:
There are a few main differences between toads in Kansas, listed above, and Spadefoots, listed below.
-
Spadefoots have vertical pupils like a snake, while toads have horizontal pupils.
-
Their skin is much smoother and has very few or no warts.
-
Their back feet have bony, sharp spades that are used for burrowing into soil, sand, or loose gravel.
#6. Plains Spadefoot
- Spea bombifrons
Identifying Characteristics:
- Adult length is 1 ¼-2 ½ inches.
- Coloring is gray-brown to greenish with orange spots, and the snout is distinctly rounded and protrudes like a pug dog.
- Spade is glossy, black, and wedge-shaped.
The Plains Spadefoot lives in plains, hills, and river bottoms in Kansas. They prefer loose sandy or gravelly soil for burrowing.
Plains Spadefoot Rangemap:
Plains Spadefoot’s can survive extreme temperature changes in Kansas.
It also can change its digestive system to tolerate a diet of vertebrates, insects, or plant matter.
The Plains Spadefoot’s call is very short and sharp, similar to the quack of a duck.
#7. Couch’s Spadefoot
- Scaphinopus couchii
Identifying Characteristics:
- Adult length is 2 ¼-3 ¾ inches.
- Coloring is greenish-yellow to light brown, with irregular dark brown or black splotches that sometimes form a weblike network.
- Spade is sickle-shaped and black.
In far southwestern Kansas, the Couch’s Spadefoot lives in shortgrass prairie and desert brush. It eats many insects including beetles, grasshoppers, and ants.
Couch’s Spadefoot Rangemap:
Couch’s Spadefoots spend much of the year burrowed underground to avoid the hot and dry climate where they live. In fact, they can eat an enormous amount of food during the short rainy season and may not come aboveground for more than a year if the weather remains too dry.
The main defense of Couch’s Spadefoots is a toxin that is powerful enough to affect humans.
If handled, the chemical can cause sneezing and watery eyes!
The call of the Couch’s Spadefoot can be compared to the bleat of a lamb, starting out higher pitched and dropping lower at the end. It is short, lasting about a second.
#8. Mexican Spadefoot
- Spea Multiplicata
Identifying Characteristics:
- Adult length is 1 ½-2 ½ inches.
- Coloring is uniform brown or gray, with scattered dark spots tipped in red.
- Spade is wedge-shaped.
In far southwestern Kansas, the Mexican Spadefoot has a wide range of habitats from grassland to pine forests. It prefers loose, sandy or gravelly soil for burrowing.

The main defense of the Mexican Spadefoot is a secretion that can cause a runny nose and watery eyes, making it a risky snack for predators.
The Mexican Spadefoot’s eyes are a unique copper color with black flecks, which makes it look like a cat’s eye marble!
When calling to attract mates, Mexican Spadefoots emit a metallic, vibrating sound that lasts about 1.5 seconds.
