It happens to me all the time.
Bobcats and owls have both scared the crap outta me at some point. Hearing a bobcat scream or an owl hoot in the pitch black can seriously be un-nerving.
Ok, I have had quail leave a tree sounding like a helicopter bent for hell scare me before, but this was during daylight. 830 to be exact. And nothing else has ever spooked me like this before.
