Even though most owls are nocturnal hunters and we can’t see what they hunt, we know a surprising amount of information about their diet. An owl’s feces look like any other bird dropping, so we can’t tell what they eat. The clues to an owl’s diet lay in owl pellets--regurgitated pellets of indigestible material such as bones, fur, fish scales and teeth--because owls swallow their prey whole.
