Barn owl helps kin earn ghostly reputation

Halloween is drawing closer, and it’s definitely the one night of the year that we become acutely aware of things that go bump in the night.

While goblins and ghouls can be dismissed as mere apparitions of the imagination, some real-life feathered phantoms do roam the darkness, perhaps even in your own backyard. If so, you are more likely to have heard them than to have seen them.

If you do hear anything unusual Halloween night, chances are the sounds may have been produced by an owl.

Several species of owl reside in Northeast Tennessee, including the Eastern screech-owl, the barred owl, the great horned owl and the barn owl. A fifth owl, the tiny Northern saw-whet owl, can be found at some high-elevation locations, including Unaka Mountain in Unicoi County. A few other owls have made sporadic appearances in the region, including long-eared owl, short-eared owl and even snowy owl.

The barn owl is an owl that has adapted its ways to co-exist with humans. Even its common name refers to the fact that these owls will roost and nest in barns and other structures. They are also known to select natural tree cavities, caves and other human structures, including recesses build into sports stadiums and arenas. My most recent sightings of barn owls took place at a grain silo in Sullivan County a few years ago, a large barn located on Antelope Island State Park in Utah in 2006 and under the eaves of the old theatre on the campus of the Mountain Home Veterans Administration near East Tennessee State University back in 2000. These sporadic sightings are testimony to the overall elusive nature of this owl.

I was surprised to learn during my background research that the barn owl is the most widely distributed species of owl as well as one of the most widespread birds on the planet. This owl is also referred to as common barn owl, to distinguish it from other species in the barn-owl family Tytonidae. Owls in this family comprise one of two main lineages of living owls, the other being the typical owls in the Strigidae family. The barn owl, known by the scientific name, Tyto alba, is found almost worldwide except in polar and desert regions, Asia north of the Alpide belt, most of Indonesia, and the Pacific islands.

The genus name for this owl is Tyto, a variation of the ancient Greek word, “tutō,” which meant “owl.” The barn owl family, Tytonidae, consists of true barn owls, as well as grass owls and masked owls.

All owls are carnivores, but the barn owl specializes on rodents more than many of its kin. However, this owl will also eat other birds and insects.

Because of their pale plumage and nocturnal habits, barn owls have been saddled with such common names as demon owl, death owl, night owl and ghost owl.

Other common names include rat owl, inspired by one of its major prey items, and barnyard owl and church owl, which are two haunts where these owls often roost or perch. I also liked the name scritch owl and hissing owl, which were acquired because of vocalizations from this bird.

Barn owls have several adaptations that allow them to hunt in complete darkness. These owls have excellent hearing, allowing them to pinpoint prey even when the absence of light renders vision useless. The characteristic facial disc of the barn owl helps channel sounds toward the bird’s ears.

Even the feathers of owls have adapted to the need to stalk wary prey without revealing their presence. Specialized feathers permit owls to fly almost silently. Their feathers absorb flight noises and even alter air turbulence to keep the flight smooth and quiet. Most prey never suspect the owl’s approach until it’s far too late.

For the average person the term “owl” is representative of what is actually an extremely diverse family of birds. Worldwide, there are about 220 species of owls varying in size and habits.

Humans have come up with some descriptive names for various owls around the world. A sampling of these names includes fearful owl, pharaoh eagle-owl, collared owlet, pearl-spotted owlet, least pygmy-owl, red-chested owlet, buff-fronted owl, Stygian owl, vermiculated fishing-owl, black-and-white owl, bare-legged owl, maned owl, bearded screech-owl, spectacled owl and golden-masked owl.

Owls, according to Linda Spencer, author of “Knock on Wood: A Serendipitous Selection of Superstitions,” have inspired a mixed bag of superstitions ever since humans stood up. Owls have long been associated with the forces of both good and evil. The “hoot” or call of an owl is believed by people of many cultures to foretell death. There are some interesting ways to counter the ominous hoot of an owl, according to Spencer. Means of warding off the evil owl power include putting irons back in the fire, throwing salt, pepper and vinegar on the fire, tying a knot or taking one’s clothes off, turning them inside out and putting them back on.

According to Laura Martin, author of “The Folklore of Birds,” one of the earliest human drawings depicting owls dates back to the early Paleolithic period. The scene is of a family of snowy owls painted on a cave wall in France.

Owls have also entered the culture as symbols of wisdom and goodness. The wise old owl, Martin writes, dates back to the time of King Arthur. The sorcerer Merlin was always shown with an owl on his shoulder. During the Middle Ages owls became symbols of learning and intelligence. The Greeks didn’t fear owls as did the Romans. In fact, the owl was the sacred mascot of the Greek goddess Athena.

There’s one more owl-related myth I forgot to mention. There is a Chinese belief that owls snatch the souls of unwary people — just something you should know if you are out and about after dark on Halloween night.

Mysterious owl retains a low profile even during Halloween season

With common names such as cave owl, death owl, ghost owl, night owl and hobgoblin owl, the nocturnal hunter more widely known as the barn owl provides a fitting focus for exploration as the calendar counts down toward Halloween.

Barn owls lurk in the shadows of night, but most people would never know it unless they happen to hear some of the spine-tingling vocalizations produced by this poorly known predatory bird. Shiver-inducing shrieks and screams quite capable of piercing the veil of darkness are often produced by the barn owl. This owl doesn’t utter loud hoots like the great horned owl. Instead, the call of the barn owl is not likely one to be soon forgotten because of its raspy, nails-on-the-chalkboard nature. A hearer could easily be misled into misinterpreting the shrill vocalizations as originating from something far more ghoulish.

According to the website for the Owl Research Institute in Charlo, Montana, barn owls are the most widely distributed owl in the world, and they may be one of the most common, as well. In Montana, where ORI is located, barn owls observations are rather sparse. ORI has documented 12 barn owl nests and made numerous observations in the last 12 years, according to its website. Likewise, the barn owl is not too often observed in Northeast Tennessee and Southwest Virginia.

The barn owl is often associated with rural, agricultural areas, which is one reason they can often be found in old barns, sheds and farm silos. However, the first barn owl I ever saw in the wild was living beneath the eaves of a building on the campus of Mountain Home Veterans Administration in Johnson City, Tennessee, within walking distance of commercial buildings and the campus of East Tennessee State University.

The barn owl has no close relatives among the other owls found in the region. The barn owl is in its own unique family known as Tytonidae. The family name comes from a Greek word, Tuto, which translates as “night owl.”

Other owls in our region — great horned owl, barred owl, Eastern screech-owl, short-eared owl— belong to a family called Strigidae, which are often described as “typical owls” by ornithologists and other experts.

The barn owl is one of nature’s most perfect predators. Among animals tested by scientists, the barn owl shows an almost uncanny ability to detect prey animals by sound alone. Prey, which is often small voles or other rodents, often doesn’t know of the danger until it’s too late. The structure of the barn owl’s wings and feathers is such that these predatory birds can fly through the darkness in almost perfect silence.

Early American painter John James Audubon captured this dynamic scene of barn owls with a capture chipmunk.

There’s a heavy cost that the owl must pay for these special adaptations. According to the Barn Owl Trust, an organization founded in 1988 in the United Kingdom to conserve one of the most beautiful birds on Earth, a barn owl’s specially adapted feathers are not particularly waterproof. In addition, barn owls are unable to store a lot of body fat. The Trust’s website notes that barn owls are unable to hunt in heavy rain and are particularly prone to starvation during prolonged periods of severe weather and/or prey shortage.

Much myth and legend have arisen around the world’s owls, including the barn owl. A native tribe in California known as the Newuks believed that warriors who proved courageous and virtuous became great horned owls after death. Men who practiced wicked ways, however, were thought to become barn owls.

This owl with the white heart-shaped face has long spooked humans. The bird’s head and upper body typically vary between pale brown and various shade of gray. Especially in flight, the barn owl can look rather pale.

The barn owl is the most widespread terrestrial bird species in the world, occurring on every continent except Antarctica. In addition to its various spooky common names, barn owls are also known by such descriptive monikers as monkey-faced owl, silver owl and golden owl. Some other common names include church owl and steeple owl. This owl acquired this name for its habit of utilizing steeples or bell towers in churches as roosting locations when barns or caves were lacking.

For a bird so closely associated with people and their dwellings and related structures, the barn owl remains an enigma to many. YouTube offers a variety of videos that showcase the creepy vocalizations of barn owls. Familiarize yourself with their calls, and you’ll be more likely to distinguish a barn owl calling after dark from the more sinister specters on the prowl this Halloween.
