General

Eyes are pale yellow highlighted by thin white eyebrows. Wings are relatively long. Bristly feathers sparsely cover feet and legs. Tail is short with 3 to 5 pale bars. Sexes are similar.

Range and Habitat

Elf Owl: Resident in southwest U.S. and Mexico. Preferred habitats include deserts, thorn scrub, and mesquite or deciduous riparian woodlands; most abundant in deserts dominated by giant saguaro.

Breeding and Nesting

Elf Owl: One to five white eggs are laid in an abandoned woodpecker hole in a tree or large cactus. Incubation ranges from 14 to 24 days and is carried out by both parents.

Foraging and Feeding

Elf Owl: Eats insects, other arthropods, small mammals, and small birds. Often hovers to spook insect prey into flight, and then captures it in mid-air.

Vocalization

Elf Owl: Advertising call of the male is a high-pitched yip, "whi-whi-whi-whi-whii." Calling is most intense during early evening and near dawn, on moonlit spring nights. Mated pairs may also duet, but the female's song is softer and shorter, often a simple "peeu" note to help the male locate her. Male also gives a short flight song "CHU-ur-ur-ur." When disturbed, both sexes will give a sharp "cheeur."
