7 Types of Frogs Found in Manitoba! (ID Guide)

What kind of frogs can you find in Manitoba?”

Common Manitoba Frogs

I love finding, observing, and hearing frogs!

Even as a kid, I used to patrol the swamps by my house, catching them and then trying to sell them as pets to cars passing by. As you can imagine, no one was interested in buying my frogs, and I ended up letting them go at the end of each day. 🙂

Today, I’m providing a guide to teach you about the different kinds of frogs found in Manitoba.

One of the BEST ways to find frogs is to learn the noises they make. So, in addition to pictures, you will find audio samples for each species below!

7 Frog Species in Manitoba:

#1. Northern Leopard Frog

  • Lithobates pipiens

Types of Frogs that live in Manitoba

Identifying Characteristics:

  • Adults range from 5 to 11.5 cm long.
  • Smooth skin is green, brown, or yellow-green with large dark spots.
  • Lighter-colored raised ridges extend down the length of the back.

You can spot Northern Leopard Frogs in Manitoba near slow-moving bodies of water with lots of vegetation. You might see them in or near ponds, lakes, streams, and marshes. I love how bright green most individuals appear!

Due to their fairly large size, these frogs eat various foods, including worms, crickets, flies, and small frogs, snakes, and birds. In one study, a bat was even observed being eaten!

During the spring breeding season, the males will float in shallow pools emitting a low call thought to sound a bit like snoring. The Northern Leopard Frog may also make a high, loud, screaming call if captured or startled.

Northern Leopard Frog populations are declining in many areas, and the cause is not exactly known. It’s thought to be some combination of habitat loss, drought, introduced fish, environmental contaminants, and disease.

#2. Green Frog

  • Lithobates clamitans

Kinds of Frogs in Manitoba

Identifying Characteristics:

  • Adult body lengths range from 5 to 10 cm, and the females are typically larger than males.
  • Coloration is normally green or brown with darker mottling or spots on the back.
  • Ridges run down the sides of the back and they have webbed hind feet.

Green Frogs can be found in eastern Manitoba.

Look for them in permanent bodies of water, including lakes, ponds, swamps, and streams. They spend most of their time near the shoreline but jump into deeper water when approached. They also breed and lay eggs near the shore, typically in areas with aquatic vegetation.

The Green Frog produces a single note call that is relatively easy to identify. Listen for a noise that sounds like a plucked banjo string, which is often repeated.

To hunt, they use a “sit and wait” approach, so they are fairly opportunistic. Green Frogs will try to eat almost anything they can fit inside their mouth. The list includes spiders, insects, fish, crayfish, snails, slugs, small snakes, and even other frogs!

#3. Spring Peeper

  • Pseudacris crucifer

Manitoba Frogs species

Identifying Characteristics:

  • Adults are small and range from 2.5 to 3.8 cm long.
  • They’re typically tan or brown, with the females being lighter in color.
  • Both males and females usually feature a darker cross or ‘X’ on their back.

These tiny frogs can be found all over eastern Manitoba.

You’ll typically spot Spring Peepers on the forest floor among the leaves. However, they do have large toe pads that they use for climbing trees.

Spring Peeper Range Map

You can find them in ponds and small bodies of water in the spring, where they breed and lay eggs. After hatching, the young frogs remain in the tadpole stage for about three months before leaving the water.

Spring Peepers get their name from their distinctive spring chorus. They’re thought to sound a bit like baby chickens’ peeps, and they are most often heard in early spring! LISTEN BELOW!

Their calls are very distinctive, and once you know what to listen for, these frogs are very easy to identify by sound.

#4. Gray Treefrog

  • Dryophytes versicolor

Common Frogs species in Manitoba

Identifying Characteristics:

  • Adult body lengths range from 3.8 to 5 cm.
  • Mottled gray, green, and brown coloring. Look for a whitish spot beneath each eye.
  • Bumpy skin, short snouts, and bright orange on the undersides of their legs.

Chameleons aren’t the only animal that can change colors! This incredible frog can slowly change colors to match what it’s sitting on to camouflage itself. They can vary from gray to green or brown. It’s common for their back to display a mottled coloring, much like lichen.

Gray Treefrogs are ubiquitous throughout southern Manitoba. You’ll spot them in a wide variety of wooded habitats, from backyards to forests to swamps.

They stick to the treetops until it’s time to breed. Gray Treefrogs prefer to mate and lay eggs in woodland ponds without fish. They’ll also use swamps and garden water features.

Gray Treefrogs are easier to hear than to see.

Listen for a high trill that lasts about 1 second, which is commonly heard in spring and summer.

*Gray Treefrogs are essentially identical to Cope’s Gray Treefrogs. The only way to tell the difference is to listen to their breeding calls. You can learn more by visiting this site.*

#5. Wood Frog

  • Lithobates sylvaticus

wood frog

Identifying Characteristics:

  • Adult body lengths range from 3.8 to 8.25 cm.
  • Coloration is various shades of brown, gray, red, or green, with females tending to be more brightly colored.
  • Distinct black marking across the eyes, which resembles a mask.

As the name suggests, Wood Frogs are found in Manitoba in moist woodland habitats, including forested swamps, ravines, and bogs. They travel widely and visit seasonal pools to breed.

This incredible little frog has a wide range across North America. They have adapted to cold climates by being able to freeze over the winter. Their breathing and heartbeat stop, and their bodies produce a type of antifreeze that prevents their cells from bursting. In the spring, they thaw and begin feeding again.

Interestingly, Wood Frogs seem to be able to recognize their family. Scientists have found that as tadpoles, siblings will seek each other out and group together!

Wood Frogs are one of the first amphibians to emerge after the snow melts.

Listen for a call that sounds a bit like a clucking chicken near vernal pools and other small bodies of water!

#6. Mink Frog

  • Lithobates septentrionalis

mink frog

Identifying Characteristics:

  • Adult body lengths range from 4.8 to 7.6 cm.
  • Coloration is green with darker green or brown blotches. Cream, yellow, or white underside.
  • Bright green lips and webbed hind feet.

The Mink Frog gets its name from the unusual scent it produces when handled. It’s believed to smell like a mink or rotting onions!

These small frogs are primarily aquatic and can be found in ponds, lakes, swamps, and streams, particularly in wooded areas. They favor areas with water lilies which they utilize for protection from predators.

During the breeding season, the males produce a rapid series of croaks thought to sound like tapping a hammer on wood.

When large numbers of Mink Frogs gather together in Manitoba and croak in chorus, many people think it sounds like horses walking down a cobblestone street. 🙂

Interestingly, tadpoles remain in the larval stage for a year before turning into a frog!

#7. Boreal Chorus Frog

  • Pseudacris maculata

boreal chorus frog

Identifying Characteristics:

  • Adults range from 2.5 to 3.8 cm long.
  • Coloration is brown, olive green, or tan with three dark stripes down the back that are sometimes broken into blotches.
  • Prominent black stripe on each side from nostril, through the eye, and down the sides to the groin.
  • Looks very similar to the Western Chorus Frog. Boreal Chorus Frogs are distinguished by having shorter legs.

While the Boreal Chorus Frog can be common in Manitoba, they are rarely seen. They’re small and secretive, inhabiting moist meadows and forests near wetlands.

These frogs breed in shallow temporary ponds and pools such as flooded fields and roadside ditches. They require waters free of fish; otherwise, most of their eggs and tadpoles would be eaten!

Males produce a loud chorus of calls at breeding sites, which are easy to identify.

The sound has been compared to someone running a finger over the teeth of a comb (“reeeek“). You’re most likely to hear the calls in the late afternoon or evening.

  1. I saw a very large Leopard Frog in my garden. It was larger than the palm of my hand. I live near the Seine River.

  2. Found the tiniest frog I have ever seen. It was patterned like a leopard frog but was light brown where green normally would be. It was about 1cm long. Super tiny. It was seen at Kildonan Park in Winnipeg, June 27 2023. I wish I took a picture but didn’t have cell phone on me.

  3. Leopard Frogs and Boreal Chorus Frog. Bother types were found in our window well. We helped them out…8 so far!😳🐸

  4. Sitting in the semi dark and a frog kept onto a shrub rose branch. I thought, oh nice green tree frog..but it was the size of a leopard frog. Tried for a photo…lots of window and backlight glare. Nothing I’ve ever seen in Manitoba.

    1. When I was a little girl, up at my Grandfathers farm in Meleb, a bright green tree frog showed up one year. The only one I’d ever seen, and I spent all summers throughout my childhood catching frogs. Never seen another like it again. White lipped tree frog is what Google says it is. Strange it’s not on the list either. Maybe an anomaly.
