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.
Owls are birds of prey. Owls feed on a wide variety of prey including mammals, other birds, insects, and reptiles. There are even some species of owls that live in Africa and Asia that feed on birds. Owls cannot chew their prey since, like all birds, they do not have teeth.ost owls are nocturnal. Most owls are active at night. A few species (such as the pygmy owls) are active in the early morning or at dusk while some (such as the burrowing owl and the short-eared owl) are active during the day.
