Frogs in Montana: identification guide and where to start looking

1. What are the most common frog species in Montana?

The boreal chorus frog (Pseudacris maculata) and Columbia spotted frog (Rana luteiventris) are the most frequently seen. The western toad (Anaxyrus boreas) is also common, though it's a toad, not a true frog. The northern leopard frog (Lithobates pipiens) is present but less common in some areas.

2. Where in Montana can you see frogs most frequently?

Best bets include the shallow wetlands of the Prairie Pothole Region in eastern Montana, the riparian areas of the Yellowstone and Missouri river drainages, and mountain ponds in the west. Look for them near cattail marshes, beaver ponds, and flooded meadows. Start with relatively low elevation sites in spring.

3. When is the best season for frog sightings in Montana?

Spring (April to June) is the prime window. Frogs emerge from hibernation and gather at breeding ponds. A warm, rainy April evening can produce large choruses. By midsummer many species become less active, though juveniles may still be found near water.

4. How can you identify different frog species in Montana?

Key field marks include the dark eye stripe of the northern leopard frog, the three dark stripes down the back of the boreal chorus frog, and the reddish belly of the Columbia spotted frog. Lookalikes: western toads have warty skin and parotoid glands, while true frogs have smooth, moist skin. Size varies from 3/4 inch (chorus frog) to 4 inches (spotted frog).

5. What do Montana frogs sound like?

The boreal chorus frog makes a short, scratchy trill that sounds like running a fingernail across a comb. The Columbia spotted frog gives a series of low grunts or clucks. Northern leopard frogs produce a snore-like call followed by grunts. Listen near water on spring evenings.

6. What are the best tips for spotting frogs in Montana?

Move slowly and scan the edges of ponds and streams. Look for floating mats of algae where frogs may bask. Use a flashlight at night to spot eye shine. Visit after rain when frogs are more active. Bring a field guide and check out our/animals/frogpage for more tips.
