SPECIES INFO

The Elf Owl (Micrathene whitneyi) is a member of the owl family Strigidae that breeds in the southwestern United States and Mexico. It is the world's second smallest owl, the first being a Pygmy owl. They are 5-12 inches tall and have a wingspan of 15-16 inches and short tails. Their primary projection extends nearly past their tail. They have fairly long legs and often appear bow-legged. They are 1-1.4 ounces.They can often be heard just after dusk or at sunset, calling to each other. Their call is a high pitched whinny or chuckle. The male and female dart around the trees and call back and forth.

Reproducing

They choose an abandoned woodpecker cavity and the female lays 30 round white eggs. She incubates them for about 3 weeks before the chicks hatch. The young owlets fledge at about 10 months. Usually, chicks are born in mid-June or early July. By the end of July, they are almost always fledged and ready to set out on their own.

Behavior

They raise their young in north-facing woodpecker cavities in Saguaro cacti, sycamores, cottonwoods and other hardwood trees. They are often found in chapparal habitat, and are easily found during their breeding season.

Migrating

The elf owl migrates to Arizona and New Mexico in the spring and summer and in the winter it is found in central and southern Mexico.Migrant Elf Owls return north in mid-August or early May.

Diet

Elf Owls feed mainly on insects and therefore occupy habitats with a ready supply of these. Agaves and ocotillos are ideal places for foraging as moths and other insects may sleep in their flowers. Elf owls are known to eat scorpions, somehow managing to cut off the stinger. They are often seen chasing after flying insects, with a flight similar to a tyrant flycatcher's just after dusk.

Subspecies

M. w. idonea, the subspecies in southernmost Texas to central Mexico is resident, as are the isolated M. w. sanfordi of southernmost Baja California and M. w. graysoni of Socorro Island, south-west from the tip of Baja California. The latter apparently became extinct in the 20th century, probably around 1970.
