2 Types of Toads Found in Michigan! (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 Michigan.
#1. American Toad
- Anaxyrus americanus
- 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 Michigan.
The subspecies you can find here is the Eastern American Toad, the larger of the two.

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. Fowler’s Toad
- Anaxyrus fowleri
- Adult length is 2-3 inches.
- Coloring ranges from gray to brownish green or olive, with dark splotches on the back that have 3 or more warts in them. Adults have a pale stripe down their backs.
- The belly is usually white or yellowish, sometimes with dark spots breaking into smaller flecks.
Fowler’s Toads are fairly abundant in Michigan.
They live in a wide range of habitats including forests, river valleys, farms, and urban and suburban gardens. They eat a variety of insects, and are very good at pest control!

The mating call of the Fowler’s Toad only lasts about 1-4 seconds. Listen for a nasal “wa-a-a-ah” sound, similar to the call of a Canada Goose.
The Fowler’s Toad is unique in that its mating call attracts both males and females.
The male toad will occasionally try to mate with another male, only realizing his mistake when he hears the other male toad’s warning chirp.
