The
barn owl can readily be distinguished from other owls by its unique
shape, colour 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.
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.
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.
