Fun Facts About Owls 1 Ornithologists study those pellets to learn more about an owl's diet. 2  Owls have zygodactyl feet with two toes pointing forward and two toes pointing backward, and all their toes have sharp talons. 3  This gives the birds a stronger, more powerful grip so they can be more effective predators. Several owls species have ear tufts on their heads but they aren't ears at all. 2  These tufts of feathers may indicate the bird's mood, help keep it camouflaged or be used to show aggression.

Barn Owl Life History Barn Owls eat mostly small mammals, particularly rats, mice, voles, lemmings, and other rodents; also shrews, bats, and rabbits. Most of the prey they eat are active at night, so squirrels and chipmunks are relatively safe from Barn Owls. They occasionally eat birds such as starlings, blackbirds, and meadowlarks. Nesting Barn Owls sometimes store dozens of prey items at the nest site while they are incubating to feed the young once they hatch.
