I should know what making this rythmic call ... I've heard them forever
on summer nights, but I guess it's always been dark. Just an hour ago
I heard one in a sapling tree and I looked around with a flashlight
trying to find the singer. It kept singing as I circled the tree for
several seconds, and finally muted when I got in close.
The recording is pretty crappy ... it was a test run with a gift '70s
vintage JVC consumer stereo electret mic into my last legs TCD-D8. But
the caller in question can be heard doing a "ch ch ... ch ch ch".
I really like it when a bunch of these singers get going in staggered
timing. Heard a pair a couple of nights ago that were a half step
apart in pitch and doing call/response triplets. Sometimes I hear
doublets and quadruplets, and there can be large choruses going. So
help a night nature ingnoramus out and tell me what's making that call.
