species distribution map JPG -- Species Photo

Western chorus frogs are North Dakota's smallest frogs, reaching a body length of 1 inches. Colors range from buff to gray, or green with three dark stripes down the back. Chorus frogs have small adhesive discs like tree frogs, but they do not climb. Their diet consists of small insects.

Chorus frogs are best known for their distinctive call. In early spring, the males call in small bodies of shallow water. Their call has been described as a chirping sound. It can be duplicated by running your finger across the teeth of a pocket comb. The call of the chorus frog can be heard from the middle of April to the middle of June. Western chorus frogs can be found statewide.
