The spring peeper has an irregular dark "X" marking on its light tan to brownish back. They have a dark bar that runs between the eyes and slightly enlarged toe pads that allow them to grip and climb on vertical vegetation.

Species range (darker) in Wisconsin

They are one of the first frogs to begin calling in spring and most successfully reproduce in fishless wetlands. Their call is a very shrill and repetitious "peep." Spring peepers live primarily in moist forests and larger woodlots and breed in wetlands within and adjacent to these habitats. The Wisconsin Frog and Toad Survey shows that this species is still widespread and common.
