>The Nova Scotia Museum of Natural History is currently planning an >exhibit about sounds in nature. You should call Ohio State University (main number 614-292-6446) and get the Bioacoustics Lab (if the operator can't find it, ask for the Museum of Biological Diversity). I believe they have lots of animal sound recordings. I wonder if you could modify the Exploratorium's exhibit about sound (the one where you blow air through cavities to create vowel sounds).
