The recording is a constant delight and will probably make you aware of the source of many sounds you have heard but not identified before. Don't be surprised to say, "So THAT'S what that is" many times while listening to the tape or CD. Also be prepared for surprises. Think you hear cats fighting outside your window at night? They may be cats, but they also could be raccoons, which often sound remarkably like angry felines. That strange, ghostly hiss or scream you may have heard at night in the country? An angry cat perhaps, but it might be a barn owl. And there are many other special sounds identified here: the rhythmic calls of nightjars like the whippoorwill, the trills and croaks of amphibians, the surprisingly snort of the white-tailed deer.

If you spend a lot of time outdoors, you must have this guide. Take it on a camping trip with you, if you have a portable CD player or cassette player. Those night woods will not seem so forbidding anymore once you know that most of the time, the strange and fascinating sounds you hear are made by completely harmless creatures.
