Michigan Frog and Toad Survey Audio Training Files

These training audio files will help you learn the 13 species of frogs and toads that are found in Michigan. Most of the calls were recorded here in Michigan. Study the recordings so that you know the difference between the species and refer back to them when you hear something you are not sure how to identify. The species on the recordings are generally in the order that you would hear them from early spring to early summer. Suggested times and temperatures are included in the survery instructions. Keep in mind that frogs will sometimes call at lower temperatures than those suggested, but they are not usually calling at their peak abundance and the calls are generally slower in cooler temperatures.
