Owls are birds that are usually awake at night. They sleep in the day and hunt in the dark. Most owls eat mice and other small animals.
Owls have very big eyes, so they can see well when there is little light. But an owl cannot move its eyes like we do. Instead, it turns its head. An owl can turn its head a long way around, much more than a person can.
Owls also have excellent hearing. Some owls can find a mouse under the snow only by its sound. Their soft feathers help them to fly without noise, so the mouse does not hear them coming.
Farmers often like owls, because owls catch mice in their fields.
