Saskatchewan's Frogs and Toads

Wood frog

There are 6 species of frogs and toads in Saskatchewan.

Boreal Chorus Frog
Boreal Chorus Frog are hard to see but easy to hear, especially in early spring when the males sing day and night to attract females and to defend their territory. The chorus of high-pitched trills has been compared to a fingernail running along the edge of a plastic comb.

Boreal Chorus Frog are small (just under 4 cm), smooth-skinned frogs. They are grey-green to brown with 3 dark stripes down their back, a dark stripe through their eyes, and a white stripe along their upper lip. They’re usually found in small, shallow, fish-free ponds surrounded by short, grassy vegetation in both prairie and forest settings.

The females lay their eggs in clusters, and they hatch in 1-4 weeks. The tadpoles turn into frogs after about 2 months.

Boreal Chorus Frog can be found from British Columbia to Quebec and up into the Yukon and the Northwest Territories as well as in the central United States as far south as Arizona. In winter, they try to find a mammal burrow or other underground cave below the frost line where they can safely hibernate.

Northern Leopard frog

Northern Leopard Frog
Northern Leopard Frog owe their name to the dark round spots on their green and brown back and legs. Prominent light-coloured folds of skin run down either side of their back, and they have a white belly. They are a medium-large frog, up to 11 cm in length.

Northern Leopard Frog are found near ponds and marshes across Canada and in most parts of the United States. They can be found as far north as Great Slave Lake and in the mountains. They are also known as Meadow or Grass Frog because they sometimes hop up onto lawns and golf courses in the summer when they've finished breeding.

Northern Leopard Frog will eat anything they can fit in their mouth and have been known to eat small birds and snakes. They sit still, wait for their prey, and then leap and grab it with their long, sticky tongue.

Wood Frog
Wood Frog are reddish-brown, medium-sized (3-8 cm long) frogs with prominent ridges on their back, a black mask over their eyes, and a white belly. Some have a white stripe down their back. They can change colour very rapidly, turning dark when cold to absorb more heat.

Wood Frog are found in every province and territory of Canada as well as the northeastern and central United States. They are the only frog found north of the Arctic Circle and are one of the few frogs found in Alaska. They prefer moist woodland areas and hibernate under the leaf litter covering the forest floor.

Like several northern frogs, including the Boreal Chorus Frog, Wood Frog tolerate below-zero temperatures by increasing the amount of glucose in their blood, which lowers the freezing point and stops ice crystals from forming.

Male Wood Frogs announce the start of the early spring breeding season with small clucking sounds. Over a short 1-2 week period, the frogs will mate and the females will each attach up to 2,000 eggs to underwater vegetation. The tadpoles eat plants, while the adults use their long, sticky tongue to capture insects, spiders, slugs, worms, and snails.

Wood frog

Canadian Toad
Canadian Toad are found in river valleys and around lakes in the grasslands, aspen parklands, and boreal forest of the Canadian prairies and south to the Dakotas and Minnesota. They’re medium-sized (up to 9 cm) and grey-green to brown with brownish-red warts. Unlike the Great Plains Toad, they have grey spots on their light-coloured belly and the raised ridges on their head join to form a bump between their eyes.

Canadian Toad are easiest to spot in the spring when they congregate at breeding ponds. The males call to the females with a high-pitched trill that repeats every 15-20 seconds. Once breeding season is over, the toads spread out into the grasslands and aspen parklands, although they generally stay close to water. Their mottled earthy colors are good camouflage.

Canadian Toad hibernate underground below the frost line in burrows they've dug using the bony lumps on their rear legs.

Great Plains Toad
Great Plains Toad are medium-large (up to 11 cm), ranging in colour from pale brown-grey to olive, with dark blotches and numerous small warts. Unlike the Canadian Toad that share the same habitat, Great Plains Toad have a solid white belly and the L-shaped ridges around each eye fuse in a V rather than a lump between the eyes.

Great Plains Toad can be found in the grasslands of southern Alberta, Saskatchewan, and Manitoba and south into the central plains of the United States. They breed in temporary pools, ditches, and dugouts, laying long strings of up to 20,000 eggs. The eggs hatch in about 2 days and the tadpoles turn into frogs after 6 weeks.

Great Plains Toad hibernate in underground burrows from October to April. They are more active at night and escape the heat of the day by digging shallow burrows in loose soil. During a severe drought, they can remain inactive underground for extended periods of time.

Great Plains Toad have large home ranges and can travel over a kilometer between breeding sites, summer habitats, and hibernation sites. When threatened, they puff themselves up with air, lift themselves up on all 4 legs, and lower their head. Poisonous secretions in their warts and the large glands behind their eyes help to deter predators.

Plains Spadefoot Toad
Plains Spadefoot Toad can be found on short-grass prairie from southern Alberta, Saskatchewan, and Manitoba south through the central plains to New Mexico, Oklahoma, and West Texas. They have a round body (up to 6.5 cm), short legs, a bony lump between the eyes, and a vertical pupil. They are tan to dark brown with small orange/yellow spots and a white belly. They often have 4 white stripes down their back.

Plains Spadefoot look like a frog. Unlike the Canadian Toad and the Great Plains Toad, their skin is relatively smooth and moist. They have a vertical rather than a horizontal pupil and lack the large parotoid glands behind the eyes.

Plains Spadefoot are hard to spot as they are nocturnal and spend much of their time buried in the sand to conserve moisture. They come out at night to hunt for beetles, crickets, and grasshoppers. Plains Spadefoot tunnel backwards using the sharp knobs (or spades) on their hind feet. Their tunnels can extend as much as 1 meter – no wonder they prefer sandy or gravel soil that is easier to dig.

10 Surprising Facts about Frogs and Toads

bullfrog

1. Toads and frogs have a lot in common. In fact, toads are a type of frog. But there are some differences. Most frogs have long legs and smooth, moist skin. Toads have shorter legs and their skin is dry and bumpy. Frogs lay their eggs in a clump that looks like a bunch of grapes. Toads lay long strands of eggs on underwater plants. Frogs have teeth; toads don’t.

2. Tree frogs don’t always live in trees, but all of them have toe pads to help them grip and climb. Some tree frogs are small and brightly coloured like the tropical Red-eyed Tree Frog. Others, like the Pacific Tree Frog that can be found in British Columbia, are green and beige and blend in well with their surroundings.

3. Frogs have lungs, but they can also breathe and absorb water through their skin. A thin layer of mucus keeps their skin moist and protects it from scratches.

poison dart frog

4. Frogs can’t turn their head because they don’t have a neck. What they do have is a vocal sac, a large bubble that expands below the head and above the neck. The sac can be 3 times as large as the frog’s head when it’s fully expanded and is full of air. Male frogs use the vocal sac to make their voice louder to attract a mate and defend their territory from other males.

5. The world’s smallest frog lives in Papua New Guinea and is only 7 mm long. The world’s largest frog is the Goliath frog of Cameroon and Equatorial Guinea. It’s 30 cm long and weighs 3 kilograms. Male Goliath frogs have been known to build their own ponds for the females to nest in. Using their very muscular hind legs, they make a depression in the riverbank and surround it with large stones weighing up to 2 kg.

6. Frogs are really good at jumping. Some can jump as much as 8 times their body length. Scientists have learned that frogs have a special joint that lets them unfold like a flip phone. Their legs and body line up like an arrow, ensuring both power and accuracy.

toad

7. The bumps on a toad’s back are glands. Some produce mucus to keep the toad’s skin moist when they’re out of the water. Others are granular glands which contain toxins to deter predators. American toads have a cluster of granular glands, known as parotoid glands, just behind their eyes. If they’re threatened, the toads lower their heads so that the first thing the predator will encounter is the poison-filled glands. The poison can cause serious inflammation of the predator’s eyes or throat as well as vomiting.

8. Frogs like to be together. Young frogs even swim together in schools like fish. A group of frogs is called an army, colony, or knot.

9. Millions of frogs were born each year after the Nile river flooded, so the early Egyptians associated frogs with fertility. Similarly, First Nations peoples of the Pacific Northwest view frogs as a symbol of springtime, cleansing, and rebirth.

10. People used to believe that swallowing a live frog could cure whooping cough and tuberculosis, while carrying a dried frog in a pouch around your neck would prevent epileptic seizures.

Urban Wildlife
The Wildlife Rehabilitation Society of Saskatchewan is reminding the public that trapping and relocating wild animals is not a humane solution. “By relocating an animal, we are likely placing them in unfamiliar territory without any known food, water or shelter. Not only is this poor animal going to have to fight to find resources – it could be chased off, injured or killed by other animals whose territory they have been place upon! Don’t forget that there’s also the threat of diseases being spread when we relocate animals from one place to another. Bacteria, parasites and viruses can be easily spread and harm or kill a variety of wildlife. And what about babies? Often times, relocating an adult animal means that we are leaving behind helpless and orphaned baby animals who are unable to fend for themselves. Finally - relocating an animal just opens up the space for another animal to move right on in! We really aren’t solving any problems by forceably removing animals from their homes. We understand that wild animals can sometimes be a nuisance – especially if they are in your yard or house. However, we can help you find ways to make your area undesirable so the animal will naturally relocate itself! So please do not relocate any wild animals – give our hotline a call at 306-242-7177 and we’ll be happy to help!”
