4 Types of Toads Found in Montana! (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 Montana.
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. Western Toad
- Anaxyrus boreas
- Adult length is 2-5 inches.
- Coloring can range from yellowish, tan, gray, or green with a pale stripe along the back. The Western Toad also has dark blotches with rust-colored edges and warts.
- Males have smoother, less blotchy skin than females.
As its name suggests, the Western Toad lives in the western part of the continent. It has a wide range of habitats, including desert streams and springs, forests, lakes and rivers, and backyard gardens with pools nearby.
Western Toad Rangemap:
Female Western Toads can lay up to 16,000 eggs at a time! They lay their eggs in long strings in shallow water.
Unlike the other toads in Montana, Western Toads don’t often hop!
Instead, they walk, picking up 1 or 2 legs at a time. You can see this unique movement below!
The Western Toad has a distinctive call that can be described as a high-pitched chirrup or chattering. Choruses of Western Toads tend to sound like flocks of geese in the distance. Click here for an example!
#2. Great Plains Toad
- Anaxyrus cognatus
- 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 eastern Montana 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. Woodhouse’s Toad
- Anaxyrus woodhousii
- 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 eastern Montana, 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.
Though not as common, the Canadian Toad (Anaxyrus hemiophrys) is a close relative of the Woodhouse’s Toad that lives in the United States. It is generally smaller, with an average length of 1 1/2 to 3 inches and brownish coloring. The Canadian Toad is typically found in or very near water. It spends the cold winters of its habitat in the United States underwater, in hibernation groups. One subspecies of the Canadian Toad, the Wyoming Toad, was discovered and had a limited population in Wyoming. It is now listed as extinct in the wild, though some do still exist in captivity.
There are a few main differences between toads in Montana, 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.
#4. Plains Spadefoot
- Spea bombifrons
- 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 Montana. They prefer loose sandy or gravelly soil for burrowing.
Plains Spadefoot Rangemap:
Plains Spadefoot’s can survive extreme temperature changes in Montana.
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.
