Periodical cicadas are back

Many thanks to Bob and Joan for allowing me to record these sounds at the Sun Foundation yesterday. These are sounds of the periodical cicada. They were a bit louder but my microphone was overwhelmed. I have encountered (and collected) these animals in 1973, 1990, and now 2007. I encountered them in Marshall, Peoria, and Tazewell counties this time. I was also alive during the 1956 swarm (but was a bit too young to remember).
