When frog are recorded in Montana

What are the most common frog species in Montana?
The three most widespread frogs in Montana are the boreal chorus frog (*Pseudacris maculata*), the Columbia spotted frog (*Rana luteiventris*), and the northern leopard frog (*Lithobates pipiens*). The boreal chorus frog is small (less than 1.5 inches) with a dark stripe through the eye. The Columbia spotted frog has a pale belly and dark spots on its back. The northern leopard frog is larger (up to 4 inches) with distinct round spots on its green or brown body. Alongside these, you might encounter the plains spadefoot toad (a true toad) and the wood frog in the western mountains. For a deeper look at frog identification, visit our/animals/froghub.
How can you identify Montana frogs by their calls?
Frog calls are a reliable way to tell species apart. The boreal chorus frog makes a short, metallic 'creek' sound, often in a series. The Columbia spotted frog produces a low, throaty chuckle. The northern leopard frog lets out a long, rattling call that lasts 1-2 seconds. Plains spadefoot toads make a short, explosive 'baa' sound. The best time to hear them is on warm spring evenings after rain. Learn more about frog vocalizations on our/wildlife/montanapage.
Where are the best places to find frogs in Montana?
Frogs are most often noticed in shallow, vegetated wetlands. Start with the Flathead Lake area and the Yellowstone River floodplain. Other reliable sites include Lee Metcalf National Wildlife Refuge near Stevensville, Red Rock Lakes National Wildlife Refuge, and Bowdoin National Wildlife Refuge. Ponds and marshes along the Rocky Mountain Front also hold good populations. For a guided approach to frog spotting, check out ourMontana wildlife travel tips.

When is the best time of year to see frogs in Montana?
Spring is prime time for frog watching. Most species emerge from hibernation in April and begin calling by May. The Columbia spotted frog breeds as soon as ice melts, often in March. Summer can be good too, especially after rains. Early morning and dusk are the best times for activity. Avoid hot, dry periods when frogs retreat to mud or water.
What do Montana frogs look like and how do you tell them apart?
Pay attention to size, skin texture, and markings. The boreal chorus frog is tiny and smooth-skinned with a dark eye stripe. The Columbia spotted frog has a light spot on its eardrum and a red-orange belly (especially in breeding males). The northern leopard frog has large, evenly spaced spots and a whitish belly. The wood frog has a dark 'mask' around its eyes and lives in forested wetlands. Lookalikes include the Great Plains toad and the western toad, which have dry, warty skin. For field marks, see our/animals/frogidentification guide.
How can you plan your frog-spotting trip to Montana?
To improve your odds, target shallow wetlands with plenty of emergent vegetation. Use binoculars and a field guide. A small flashlight with a red filter can help spot eyeshine at night. For current conditions and habitat maps, the following travel widget provides tailored information:

Are there any rare or protected frog species in Montana?
Montana currently has no state-threatened frogs, but the northern leopard frog has declined in parts of its range and is a species of concern. The wood frog is considered sensitive in some areas. Amphibian chytrid fungus and habitat loss are ongoing threats. Always wash your boots between wetlands to avoid spreading diseases. Check the Montana Fish, Wildlife & Parks website for current listings.
