Plains Leopard Frog
This medium-sized spotted frog is found in pastures, prairies and marshes. The ridge of skin along each side of the back is broken, and the small posterior section is raised toward the back. Generally tan, and the round spots on the back and sides may be brown, olive or dark green. Often has a dark spot on the snout, and the belly is white. Makes a rapid series of guttural chuck-chuck-chuck sounds.
