Everything about The Elf Owl totally explained
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 3 round white eggs. She incubates them for about 3 weeks before the chicks hatch. The young owlets fledge at about 1 month. Usually, chicks are born in mid-June or early July. By the end of July, they're 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's found in central and southern Mexico.Migrant Elf Owls return north in mid-April 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.
