Feeding Behavior
Hunts only at dusk and at night. Watches from a perch and then swoops down to take prey off the ground, or flies low, pausing to hover before pouncing. Also flies out from a perch to catch flying insects. May hover among foliage and then catch insects that are flushed from the leaves. Apparently catches all prey with its feet. May remove the stinger before eating scorpions.
Eggs
3, sometimes 2-4, rarely 1-5. White. Incubation is by female only, about 24 days, male brings food to female during incubation. Young: Female remains with young most of the time at first, while male brings food for female and young. After about 2 weeks, female hunts for food also. Young leave nest at about 27-28 days, are cared for by parents for at least several days thereafter.

Diet
Insects and other arthropods. In summer, feeds heavily on moths, beetles, and crickets, as well as katydids and other insects active at night. Also feeds on scorpions and spiders. Rarely eats lizards and other small vertebrates.
Nesting
Early in breeding season, male sings loudly and persistently at night to defend territory and attract female. In courtship, male feeds female. Male sings from inside potential nest hole to lure female to it. Nest site is almost always in old woodpecker hole in tree or giant cactus (or in utility pole). Height varies: usually 15-50' above ground in streamside sycamores, 10-30' up in saguaros.
