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.
Most owls are active year-round and most species eat every day. Owls have a low percentage of body fat during the warm months of the year. However, during the cold months, the percentage of body fat does increase in some owl species such as the Snowy Owl. These fat reserves provide energy when food is scarce.
