I was not really suprised at owl diets.  I volunteer for a raptor rescue organization.  When we release rehabbed owls we do it at specific times of day.  For instance, Screech Owls are released at dusk near businesses that have large parking lots with lots of lights and with a body of water nearby.  The parking lot lights attract lots of flying insects which the owls love.  We also release Barred Owls at dusk since they are night hunters.  Releasing them at dusk allows them to get familiar with their surroundings.  Our rule of thumb is owls with yellow eyes hunt for food at dawn and dusk (one yellow eye representing sunrise and the other representing sunset).  Owls with dark eyes, like the Barred Owl, hunt in the dark.  It isn't mentioned here specifically but a Barred Owl can hear a human heart beat from 20 feet away.  Pitty the poor menu item moving below that owl's perch. I did not know that Barn Owls are the most common owl across the globe.
