3/4" - 1-3/8" (1.9 - 3.5 cm) Females larger. Tan, brown, gray, yellow or olive. Range from light tan to dark brown, able to change skin color within this range in fifteen minutes. Underneath white, vocal sac greenish. Most have a X-shaped dark mark on back. Have little webbing on feet, rounded large discs on toes. Head short and wide with bluntly pointed snout. Dorsal skin smooth, ventral skin coarsely granular, slender legs and toes.
Peep, peep, peep, peep. A short, high-pitched note, repeated every second, that rises at the end. In unison with other peepers, makes a large chorus that sounds like the jingle of sleigh bells.
