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.
Smaller owl species have more predators, and there are more animals that prey on owl eggs and owlets. The main animals that specifically hunt owls are birds of prey like eagles. Most of the time eagles and hawks fight owls over territory, but if the owl species is small enough, or if the owl is a young owlet, eagles have been known to attack them for food.
