Tree Frogs in Wyoming: Identification Guide and Where to Start Looking
Yes, tree frogs are found in Wyoming, but only a few species. The most common is the boreal chorus frog (often mistaken for a tree frog). To spot one, head to moist areas near ponds or streams in spring and early summer. Focus on their sticky toe pads and small size for confident identification.

1. Are Tree Frogs Found in Wyoming?
Wyoming is home to a couple of species often called tree frogs, but true tree frogs (family Hylidae) are rare here. The most widespread is the **boreal chorus frog** (Pseudacris maculata), which looks and acts like a tree frog. It has small toe pads and climbs low vegetation. Another is the **Pacific tree frog** (Pseudacris regilla), found only in the far northwest corner of the state. So yes, you can find tree frogs in Wyoming, but your best bet is the chorus frog.

2. What Are the Most Useful ID Markers for Wyoming Tree Frogs?
Focus on these field marks: **size** (under 1.5 inches), **toe pads** (small but visible discs on the tips), and **color** (variable: green, tan, brown, often with a dark eye stripe or triangle between the eyes). Their skin is smooth, not warty. A key clue: chorus frogs have a dark stripe through the eye, while Pacific tree frogs have a dark mask from nose to shoulder. Listen for a short, raspy trill in spring.

3. What Are the Likely Lookalikes in the Region?
The main lookalike is the **boreal toad** (Anaxyrus boreas), which is larger (2-4 inches), has warty skin, and no toe pads. Another is the **Columbia spotted frog** (Rana luteiventris), which is bigger, has webbed feet but lacks toe pads, and is mostly aquatic. The **striped chorus frog** (Pseudacris triseriata) is nearly identical to the boreal chorus frog but has three stripes; they hybridize. Use the dark eye stripe and toe pads to separate true tree frogs from other frogs.

4. Where in Wyoming Do People Usually Spot Tree Frogs?
Most sightings occur in the **southeastern and eastern plains**, especially near the Platte River drainage, and in the **Bighorn Basin**. Look in **marshy meadows, pond edges, and slow streams** with plenty of cattails or sedges. In the west, Pacific tree frogs are limited to the **Tetons and Yellowstone** region. Start your search in **Shoshone National Forest** or **Medicine Bow National Forest** around wetlands below 8,000 feet.
5. What Is the Best Time of Year for Confident Sightings?
The best window is **mid-March through June**, right after snowmelt when frogs breed and call. Males call from shallow water or low vegetation. Early morning and dusk give the best odds. After July, they become secretive and harder to find. If you want a guaranteed look, target **ephemeral ponds** in April and May when they are most active.
6. How Can You Identify Tree Frogs by Their Call?
Boreal chorus frogs produce a **short, raspy trill** that rises in pitch, lasting 1-2 seconds. Pacific tree frogs have a **two-part call**: a short croak followed by a trill. Listen near water on warm spring evenings. The call is the easiest way to confirm presence without a visual.
