Owl Food & Hunting. By Deane Lewis. Owl Food. What do Owls eat? Owls are Birds of Prey, which means that they must kill other animals to survive. Their diet includes invertebrates (such as insects, spiders, earthworms, snails and crabs), fish, reptiles, amphibians, birds and small mammals. The main food largely depends on the species of Owl. For example, Scops and Screech Owls feed on insects mostly, while Barn Owls eat mainly mice, shrews and voles. Larger Owls such as the Eagle Owl will prey upon hares, young foxes and birds up to the size of ducks and gamebirds. Some species have specialised in fishing, such as the Asian Fish Owls and African Fishing Owls.
