This small woodland Tree Frog is usually brown, tan, or pinkish in color and like other tree frogs has visible suction cups on its feet. It has earned the Latin species name crucifer due to the large, dark X formation on its back.
In the spring these Frogs call in choruses throughout the woods, most often from water, though single males can also be heard from the trees or ground. The call is a strong peep, rising in pitch, and choruses can be nearly deafening when close by. The territorial call consists of a fluttery trill, also rising in pitch. During the summer, Peepers can be found on the forest floor amongst leaf litter and timber, and these frogs are also heard among trees in the fall, giving a weak, intermittent peep.
