Fact: The Barn Owls hearing is so highly developed that they can hunt for their prey in total darkness.
As I was sitting with my neighbors around the bonfire the other night, I saw something out of the corner of my eye. It was fast and was gone when I turned my head to look. Previously that night we heard rustling in the fallen leaves nearby. At one point I looked over and saw a small mouse. My neighbors said that recently they saw a white owl flying by at about the same time of night. That little mouse was surely that owl's dinner that night. I'm so mad that I missed a glimpse of it.
