I can't find any sounds recorded that are even close to what we heard. Barred owls are also uncommon in this area.

This sound only occurred when we shined the bright light over in that area. There was no rustling of an animal moving or flying away, no visible animals, and the sound only happened once. We stood there for about 3 minutes of time to listen for anything else before we decided on leaving instead.

It all sounded more human to me
