Food Habits. Elf owls primarily eat insects â especially moths, beetles, and crickets â but occasionally they eat small mammals and reptiles, like spiny lizards, earless lizards, blind snakes and kangaroo rats. In southeastern Arizona, elf owls change their diet based on the weather.
Since owls are birds of prey they need to hunt and kill other animals to survive. Their diet mainly includes fish, reptiles, amphibians, birds, small animals and insects. The type of food really depends on the species of owl. For example, the Asian Fish Owl and the African Fishing Owl are highly specialized at catch fish while the barn owl is specialized in catching mice.
