Identifying Frog and Toad Vocalizations

One of best ways to identify anurans (frogs and toads) in the field is by their vocalizations.  Like birds, each anuran species has a unique mating call that can be accurately identified with some practice.  Here is an excellent website where you can listen to the calls of various north American species.
