No sooner than I had hit "Send" to submit my original query, I thought "FROG!" Unfortunately, however, none of the frog voices on the link you sent are even close, nor are any of the baby birds. It's still a mystery. Your idea of something electronic is interesting in that it never seems to stop. Hmmmmm, maybe someone has put a "bug" in my neighborhood. I appreciate your trying to help. If anyone else has any ideas, please feel free to tell me. Dee Thompson Nashville, TN
