What are the most common frogs in South Dakota?
The most frequently encountered frogs in South Dakota are the boreal chorus frog, northern leopard frog, American toad (technically a toad but often grouped), and the plains leopard frog. The western chorus frog and the Great Plains toad also appear in suitable habitats. For a broader perspective on frog species, see ourfrog identification hub.
In South Dakota, 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.
How can you tell apart similar looking frog species?
The boreal chorus frog and western chorus frog are nearly identical, but the boreal chorus frog has a more extensive dark stripe through the eye. Northern leopard frogs have distinct dark spots with light borders, while plains leopard frogs have more elongated spots and a pointed snout. The American toad has warty skin and large parotoid glands behind the eyes. Always check the dorsal markings and the presence of a light line on the upper jaw to separate species.
Where in South Dakota are frogs most likely seen?
Frogs are most common in the eastern third of South Dakota, especially around the Missouri River floodplain and the Prairie Pothole region. Look in shallow marshes, roadside ditches, and cattle ponds. The Black Hills have isolated populations of boreal chorus frogs near beaver ponds.

What is the best season for frog spotting?
The optimal time is from late March through June, when frogs emerge from hibernation and begin breeding. Nighttime temperatures above 50°F with recent rain trigger the most activity. Late summer can also be good for juvenile frogs, but midday heat often drives them into cover. Early spring before vegetation thickens gives the best viewing odds.
What do the calls of South Dakota frogs sound like?
Boreal chorus frogs make a series of short, repetitive *creeeek* sounds, while northern leopard frogs produce a low, guttural snore lasting a few seconds. American toads have a long, musical trill that can last 20-30 seconds. To narrow down which frog you are hearing, combine the call with the habitat and time of year.
