The main food largely depends on the species of Owl. Barn Owls eat mainly mice, gophers and voles and will also eat small birds.
Barn owls perfer to soar, or make quartering flights, scanning the ground below for a suitable meal. When a target is located, the Owl will fly towards it, keeping its head in line with it until the last moment. This is when the Owl pulls its head back, and thrusts its feet forward with the talons spread wide - two pointing backwards and two forwards.
The force of the impact is usually enough to stun the prey, which is then dispatched with a snap of the beak.
