Creature Feature: Owls

Mysterious, spooky, wise, lovable. Depending on who you ask, owls have quite the reputation. With four species found in our area – Eastern Screech, Great Horned, Barred and Barn – it’s likely there are a few living in the woods near you.  

Fast Facts 

  • Owls can turn their neck up to 135 degrees in either direction – 270 degrees of rotation! 14 neck bones – 7 more than humans – allow owls to swivel back and forth effortlessly.  
  • Owls make virtually no noise when they fly. Their wing feathers have comb-like serrations that break turbulence into smaller currents and reduce sound.  
  • Not all owls hoot. Barn Owls make hissing sounds, Eastern Screech Owls whinny like a horse and Saw-Whet Owls are named after the sound they make which is similar to the sound of a whetstone sharpening a saw. To hear the various sounds and calls from owls across North America, check out the Audubon Owls Guide for your phone and I.D. owls on the go.

Owls come in all sizes. The largest owl in North America is the Great Gray Owl which can grow as tall as 32“. The smallest is the Elf Owl – 5-6” tall and about a mere 1 ½ ounces in weight.  

Here in East Texas, if you’re lucky you might see one of the largest owls in North America – the Great Horned Owl. At almost 2’ tall, the Great Horned Owl is adaptable to many habitats, including city neighborhoods, forested areas, coastal areas, deserts and mountains. Listen for the deep, low hoo, hoohoo, hoo that sounds like a deeper a dove’s call.  

What do they eat? 

Great at pest control, a single adult owl can eat up to 50 pounds of gophers, mice, rats and moles in one year. A barn owl family will eat up to 3,000 rodents in one growing season, but they aren’t the only thing on the menu. Owls eat insects, earthworms, fish, crawfish, amphibians, other birds and small mammals too.  

With large eyes and super-sensitive hearing, owls can find the smallest vole, even in total darkness. They use their talons to rip prey into smaller pieces, for better digestion, because they swallow the pieces whole. Bones and fur compact into a pellet which the owl later coughs up. 

Why do we need them? 

Owls play a critical role in nature’s complex food web by helping manage overpopulation. It’s easy to see why farmers like having owls around. Many will install owl nesting boxes to help with pest control, and it’s cheaper and safer than poison. 

Unfortunately, owls, like many birds, are declining in population due to loss of habitat and increased use of chemicals. Good news is that there are ways that you can help. 

  • Use traps instead of poison when controlling rodent populations 
  • Leave dead trees as a nesting or roosting option, as long as it’s not a safety hazard for those nearby. Or consider installing a nesting box for small owls, like the Eastern Screech Owl. 
  • Reduce or minimize outdoor lighting at night, when owls are hunting. 
  • Drive slow and stay alert for flying owls and roadside birds at night.

Give a hoot

Mysterious, spooky, wise, lovable. Depending on who you ask, owls have quite the reputation. With four of the 19 North American species found in our area – Eastern Screech, Great Horned, Barred and Barn – , it’s likely there are a few living in the woods near you. But what do we really know about these birds of prey? Here are 10 fun facts to unravel some of the mystery surrounding these amazing creatures.

Hunting Facts

Fact #1 Incredible hunters, owls have super-powered hearing that allows them to track prey under leaves, dirt and snow. Their hearing is especially sensitive to high-frequency sounds, like rodent squeaks. Studies have shown that Barn Owls are able to catch their prey in absolute darkness just by picking up the sound of rustling leaves.

Fact #2 Owls can turn their neck up to 135 degrees in either direction – 270 degrees of rotation! 14 neck bones – 7 more than humans – allow owls to swivel back and forth effortlessly. Most mammals would be hindered by the lack of blood flow to the brain and eyes, if they were able to rotate that far. However, owls have a unique type of reservoir system at the base of their head which prevents damage to blood vessels while rotating.

Fact #3 Owls make virtually no noise when they fly. Their wing feathers have comb-like serrations that break turbulence into smaller currents and reduce sound. The soft down feathers also help to muffle noise.

Fact #4 An owl’s eye is not a true eye “ball”. Instead, its tube-shaped and doesn’t move which requires them to rotate their entire head to look to the side. This inconvenience comes with an advantage, though. The binocular vision helps them focus on their prey and boosts their depth perception. Owls may have the most efficient vision of any animal. Depending on the species, their vision is 35 to 100 times greater than humans.

Food Facts

Fact #5 Owls swallow their food whole and then cough up the carcass. Using their strong talons to crush their prey, owls swallow small animals whole. If too large, they use their beaks and talons to rip prey into smaller pieces. Nourishing parts are digested and parts that can’t be digested, like fur and bones, become compacted into a pellet which the owl later regurgitates

Fact #6

Great at pest control. A single barn owl family will eat up to 3000 rodents within 4 months. A single owl can eat 50 pounds of gophers in a year. Farmers frequently install owl nesting boxes to help with pest control. It’s cheaper and safer than poison, which kills many owls and other predators each year as the poison passes on from the prey.

Fact #7 Rodents aren’t the only thing on the menu. Owls eat insects, earthworms, fish, crawfish, amphibians, other birds and small animals. Occasionally, owls will attack and eat smaller owls. Larger owls, like the Great Horned Owl will attack a Barred Owl, which have been known to attack the Western Screech Owl.

Fun Facts

Fact #8 Owls have been depicted throughout history, from ancient Egyptian hieroglyphs to the 30,000 year old cave paintings in France. Ancient Greece recognized owls as a symbol of learning and knowledge and were often seen as a companion to Athena – goddess of wisdom. Unfortunately, owls were seen by many cultures throughout history as a symbol of impending death or evil and affiliated with witches or the unnatural. This fear led many cultures to attempt to rid themselves of nearby owl populations.

Fact #9 Not all owls hoot. Barn Owls make hissing sounds, Eastern Screech Owls whinny like a horse and Saw-Whet Owls are named after the sound they make which is similar to the sound of a whetstone sharpening a saw.
