Range

All four of the Southwestern deserts. The barn owl occurs in great numbers in Southern California.

Habitat

Hunts in areas rich in rodents, along desert washes and canyons, where trees for perching are available.

Description

The barn owl can readily be distinguished from other owls by its unique shape, color and voice. This distinctive, medium-sized owl grows 15 to 20 inches in height. It has long, feathered legs and makes a loud, rasping hiss, rather than the hoot associated with other owls.

The Barn Owl is primarily white with buff, yellow and tawny shadings. It is delicately freckled with dark specks and the blending of colors in day-light has led some to call it, the "golden owl." Other common names are for it are the "White Owl" and "Monkey-faced Owl."

The barn owl's face is arresting. There are no ear tufts. The eyes and beak are completely encircled by a heart-shaped facial ruff of white, rimmed with tan while slightly curved feathers radiate out from the small, dark eyes.

The eyes of owls look forward in a fixed position and cannot move to the side, as the human eye can. Therefore, to see to the side or back, the owl must turn its whole head. They see extremely well at night. Their hearing must be extremely acute also, for it is known that a barn owl can strike a mouse in the dark.

Habits

Barn Owls are more nocturnal than other owls. They wait until dark before starting out to hunt, except when the demands of their young may start them hunting at twilight. Normally, before daylight, they retire to some shadowed or enclosed area in an old building, a hollow tree or a hole in a rocky cliff and remain there drowsily inactive all day.

When hunting at night, the Barn Owl sweeps the fields on silent wings catching its prey with its long, slender claws. It prefers small mammals but occasionally in winter when mice and gophers are scarce, it will take small birds. The prey is tom apart and swallowed -- bones, skull and all. The indigestible parts are formed into pellets and disgorged at the roosting area or about the nest.

Life Cycle

Barn owls choose nesting sights almost anywhere, in old buildings, hollow trees and on or in the ground. No effort is made to build or even line the nest. The female lays from 5 to 7 white, spotless eggs at intervals of 2 or 3 days. Incubation starts after the first egg is laid. It takes from 32 to 34 days for the first egg to hatch, so a nest may contain 4 or 5 young of different size and age.

The young are called "owlets." They are covered with snow-white down for 6 days. This is gradually replaced by a buff-colored down which develops into a thick, woolly covering that is still in evidence for about 50 days.

The little owlets are hungry all the time. Both parents are busy night after night ransacking the adjoining areas to catch an unbelievable number of small ground creatures to feed their ravenous babies.

Adult plumage is acquired in about 7-1/2 weeks, at which time, after much practicing about the nest, the young venture out for their first lessons in flying and hunting.

The Saguaro Video
The Saguaro often begins life in the shelter of a "nurse" tree or shrub which can provide a shaded, moister habitat for the germination of life. The Saguaro grows very slowly -- perhaps an inch a year -- but to a great height, 15 to 50 feet.

The Desert Food ChainDesert Food Chain Video
A food chain constitutes a complex network of organisms, from plants to animals, through which energy, derived from the sun, flows in the form of organic matter and dissipates in the form of waste heat.

Prickly pear cactus are found in all of the deserts of the American Southwest. Most prickly pears have large spines on their stems and vary in height from less than a foot to 6 or 7 feet.
