​3. THEY SOMETIMES EAT OTHER OWLS.

Not only do owls eat surprisingly large prey (some species, like the eagle owl, can even grab little deer), they also eat other species of owls. Great horned owls, for example, will assault the barred owl. The barred owl, in turn, sometimes consumes the Western screech-owl. In fact, owl-on-owl predation may be a reason that Western screech-owl numbers have decreased.
