This is an effective means of learning to identify the different sounds of frogs. Serious scientists that are studying frogs will find this an interesting resource. We found that children were interested in the sounds of frogs. They were surprised that frogs were making many of the unusual noises. Topics discussed include the Biological Significance of Frogs, mating calls and more.
Interesting information is shared about the mating calls and a discussion on hybrid frogs.
The listener can hear each of the parents calls from different species and compare them with the recorded sounds of the young after interbreeding. Some photos are included for a few different frogs, although it would be nice if the booklet included photos to identify each of the frogs that you listen to. Many of the frogs that are recorded are from Florida. I recognized the beautiful night symphonies from my youth. An enjoyable night of listening to almost an hour of frog sounds.
