What's Going On?

The Frog Tracker lets you listen to the calls of different North American frogs. All of the sounds you hear are "sound loops" -- in nature, the calls of individual frogs have more range and variance. Frogs have been making their calls for hundreds of millions of years. Most frog calls are used to attract a mate during springtime. However, some frogs will call year round, whether they are mating or not. Each species of frog has its own unique call. To learn more about frog calls, visit "The Amazing Adaptable Frog" .

About the Sounds
The sounds and frog images for the Frog Tracker were generously provided by Lang Elliot of Nature Sound Studio and Carlos Davidson. We encourage you to visit their Web pages where you can listen to the original "full-length" calls.

This exhibit requires that you have the Shockwave plug-in. Please visit our help page for more information.   This online exhibit is still under development. Comments or suggestions, e-mail:
