Even though the western chorus frog can be found through out Minnesota they are most often heard and not seen. A member of the Hylidae, or treefrog family, they are Minnesota's smallest frog ranging from 3/4 to 1 inch.
During breeding season the western chorus frogs sing in large groups, or choruses, which is how the frog got its name. The song of the chorus frog sounds something like the sound of running your finger down the teeth of a comb. I photographed this frog in Morris, MN,
