1. Which tree frog species can you find in North Dakota?
Two main tree frog species are confirmed in North Dakota: the boreal chorus frog (Pseudacris maculata) and the gray tree frog (Hyla versicolor or Hyla chrysoscelis). The boreal chorus frog is more widespread and often mistaken for a spring peeper due to its small size and high-pitched call. The gray tree frog is less common, found mainly in the eastern part of the state near wooded river bottoms. For more on each species, visit ourTree Frogs animal hub.
In North Dakota, tree frogs sightings usually improve when you slow down and match your first stop to the most useful ID markers and likely lookalikes. Use thestate wildlife huband theroute guideto narrow your first area, then check access, weather, and distance before you settle in. A short walk with one clear viewing plan often beats covering too much ground, especially when habitat changes fast from open edges to brush, wetlands, timber, shoreline, or neighborhood cover.
2. How do you tell a boreal chorus frog from a gray tree frog?
Boreal chorus frogs are small (0.75–1.5 inches) with a dark stripe through the eye and a three-striped back pattern. Gray tree frogs are larger (1.25–2 inches) with a mottled gray or greenish coloration that changes with background, plus bright yellow patches on their inner thighs. The best field mark is the call: chorus frogs make a rising trill, while gray tree frogs produce a short, melodic trill that lasts about half a second.
3. Where in North Dakota are you most likely to see tree frogs?
Start with any permanent or semi-permanent wetland in the eastern half of the state, especially along the Missouri River and its tributaries. In the west, tree frogs are rare but occasionally found near stock ponds and springs. The Turtle Mountains and Pembina Gorge are reliable spots for gray tree frogs. Listen for calls after dusk from May through July near cattail marshes or wooded sloughs. For detailed maps, check ourNorth Dakota wildlife page.

4. When is the best time of year to look for tree frogs in North Dakota?
Timing is everything. Tree frogs emerge from hibernation in early spring (late March to April) and begin calling soon after. The peak breeding window is May through June, when males call loudly from vegetation near water. After breeding, they become harder to find as they disperse into woodlands. Early morning or just after sunset on warm, humid evenings gives the best odds.
5. What gear do you need for successful tree frog spotting?
A good headlamp with a red light helps you locate frogs without startling them. Rubber boots or waders keep you dry in marshy terrain. A simple field guide or smartphone app like iNaturalist helps confirm identification. For more resources, visit ourTree Frogs animal huband theNorth Dakota wildlife page.
