Owls have one ear that’s higher than the other. This helps them locate the source of a sound in three dimensions: left or right, near or far, and up or down. How could this ability help this Barn Owl?
Have a friend move out of your sight and clap from different places, some high and some low. Your head will turn to find the direction of the sound. We humans have trouble finding the height of a sound. Try tipping your head sideways to see if it helps you.
