Hi, all.
This may be slightly off thread, but the Chinese used a cricket as a warning device. I received a cricket box as a gift one Christmas, and it included the history. The cricket chirped continually within, but when it stopped, this meant that an intruder was lurking about.

I am certainly no ornithologist, but I am impressed with the various responses.
C.I. Galapagos, huh. Well, perhaps you can add a corollary to Darwin's theory
