While taking broken tree pics, under full cloud cover, in pitch dark, 4am in a small valley.

begins, rock hits truck, then mimic "gahawk", then whoo from east across creek, then mimic tries again "gaahawk", then I say "that was something",not knowing what just heard, then several whoo and me exchange, about 3:55 another rock hit, ongoing whoo, then near end loud rock hit, and I say "think that was a rock, or a stick", end.
 I like to quietly say "rock", to mark hits on recordings usually. I think this was mimics intent, but was having trouble with the "R" sound and made second try. Tone sounds similar to my voice, I think. Mimic must have been nearby, in woods, near parking area west of creek, where I was.
