Walt,
I replied to Rich before reading this post. If a small bird flew close
enough to the mic it could have sounded like a flying dinosaur going by.
I believe the croaking sound you refer to was the pre-dawn song of
Ash-throated Flycatcher usually heard in the 30-60 minutes before
sunrise in the spring. Unfortunately the sound posted on enature.com
doesn't reflect this but a fair example is on my Stokes Guide to
Western Bird Songs. I have other longer versions in my personal
collection.
