Everything You Wanted to Know About the Great Horned Owl

I have always had an interest in nature and birds of prey in particular. Join me in learning about these majestic creatures.

The Great Horned Owl is the most common owl in North America. As one of the largest and most recognizable members of the owl family, the Great Horned Owl is famous for its feathered tufts that resemble horns.

The Great Horned Owl is extremely adaptable and can be found almost anywhere from the southern tip of South America all the way to the Arctic. Exceeded in size only by the Snowy Owl, the Great Horned Owl is the most powerful and aggressive owl across the America’s and has earned its reputation as a fierce and determined hunter and defender.

The Great Horned Owl is quite large and can weigh up to five pounds. As with other birds of prey the female is typically larger than the male and can measure up to 25 inches in length. Males, being smaller, will usually measure closer to 20 inches. Their wingspan is impressive and can reach up to five feet from tip to tip.

There can be a lot of variation in the color of their plumage depending on their geographic location. Owls found in the arctic regions tend to be lighter in color while those found farther south can be a dark chocolate brown. Various shades of grey, brown and black with patterns and barring throughout are also common.

The famous horns are actually neither horns nor ears but large feathered tufts that get tucked back in flight. Their eyes are a bright glowing yellow and they possess very large, powerful talons.

Habits and Breeding

The Great Horned Owl will typically nest in a tree hole but can be found in stumps, caves or even in an abandoned nest. They do not build their own nests but will seek out the abandoned nest of a hawk or eagle.

The Great Horned Owl is somewhat unique in that they will begin the nesting and breeding process as early as January or February. Like other birds of prey they are monogamous and a breeding pair can produce anywhere from one to five eggs with two being the norm. The incubating duties are done by the female and will last from four to five weeks while the male hunts and brings food.

The owlets will start roaming in six to seven weeks and will fly after ten weeks or so. The young owls will stay with the parents through the summer and will slowly distance themselves and finally leave come autumn. While raising their young, the adult Great Horned Owls will fiercely defend their nest and have been known to even attack humans who have come too close.

This powerfully built, robust owl is an aggressive hunter and will hunt a wide range of mammals including; rabbits, squirrels, raccoons, moles and even skunks. They will also hunt birds and even other birds of prey including other owls. They are capable of carrying prey that is two to three times their weight and will hunt fish, lizards and even small alligators. Their diet is extremely varied (over 200 different animals) and with no natural predators they are certainly at the top of the food chain. Their normal hunting style is to sit motionless in a tree while scanning for prey until a victim is spotted. Given that they are largely nocturnal they will hunt primarily at night but have been known to hunt during daylight hours.

The Great Horned Owl is found only in the America’s. They are very adaptable and range from South America all the way to the Arctic regions. Those that make their home in the colder regions will normally migrate south in the winter while those that range in the warmer climates will maintain their territory year round.

With few predators other than humans the Great Horned Owl is not considered threatened at the moment. While some limited hunting and trapping of the owl still exists it is prohibited in most countries. Through education and conservation efforts the population of the Great Horned Owl is now stable. The lifespan of the Great Horned Owl in the wild is up to 13 years while in captivity they have been known to live up to 38 years.

Fun Facts

  • The Great Horned Owl is the only animal to feed somewhat regularly on Skunks.
  • Great Horned Owls are also known as Winged Tigers.
  • The Great Horned Owl, as with other owls, has fourteen neck vertebra that allow it to turn its head 270 degrees.
  • In addition to having excellent eyesight, which is about 100 times that of a human, the Great Horned Owl is also capable of hunting with just its keen sense of smell.
  • They also have tremendous hearing and can determine the height that a sound is coming from. They tilt and turn their head until they get an exact fix on where the noise is coming from.
  • Owls are color blind and see everything in shades of white and black.
  • The ear tufts that look like horns on their head are actually tufts of feathers called Plumicorns.
  • The Great Horned Owl can swallow some of its smaller prey whole. They will later regurgitate unwanted bone, fur, and feathers in small round pellets.
  • The Great Horned Owl is one of the earliest breeding birds starting in late January to early February.

Thanks Kristen. Every now and then I'll write a hub on a Bird of Prey although it's been a while. Maybe I'll get back to it soon. Thanks for the vote, have a great weekend.

Kristen Howe from Northeast Ohio on July 25, 2015:

Sure wish I could have but my phone does not take pictures at night, not a smart phone. Ill show them this, it was truly amazing. I wish someone believed, aww but you do. Oh by the way this was in southern Iowa40 miles from the Missouri border, in the country.

Bill De Giulio (author) from Massachusetts on September 19, 2014:

Hi Penny. You're not seeing things, indeed the Great Horned Owl can grow to over 2 feet. Lucky you to see one by the side of the road. Pretty funny that your family thinks your sleep deprived. Try taking a picture, maybe then they'll believe you :)

Thanks for stopping by, have a great weekend.

Penny Godfirnon from Southern Iowa on September 19, 2014:

So glad I came across your hub. My family has been making fun of me for years now when I came home from my night job and told them I saw an owl somewhere between 2 and 3 feet tall. They said I was sleep deprived! I know what I saw he sat beside the road and never moved as I passed. I think he looked like the great horned owl, but I passed quickly on the highway. Now I know there are owls over 2 feet tall.

Bill De Giulio (author) from Massachusetts on January 08, 2013:

I really enjoyed reading this hub, especially the fun facts! Owls are such interesting, mystical creatures. No wonder they symbolize wisdom - they sure do look wise :) Voted up!

Bill De Giulio (author) from Massachusetts on July 19, 2012:

Thanks vwriter. My sister has chickens also and she added a roof to the chicken coop to keep the hawks and owls out. The Great Horned Owl is very capable of carrying off a full grown chicken. They are also very aggressive hunters hence the nickname "flying tiger". Thanks for stopping by to read and comment.

vwriter from US on July 19, 2012:

My neighbor was awaken in the night with their chickens going crazy. He went out and found an owl trying to get at the chickens. The owl was unsuccessful because of the top fencing the neighbor had just put up. Lucky he did, he may not of had any chicken.

Great hub and pictures.

Bill De Giulio (author) from Massachusetts on July 19, 2012:

Hi mollymeadows. Thanks for the visit. They are usually pretty active at night being nocturnal. Undoubtably on the hunt. Appreciate the comments. Have a great day.

Mary Strain from The Shire on July 19, 2012:

We have these at my house; I hear them outside my window at about 1 or 2 am. And occasionally a high-pitched shriek soon after; some of our wild rabbits or squirrels going the way of all flesh. Thanks for the close up look; I've never seen them myself, since they stay hidden in the daytime.

Bill De Giulio (author) from Massachusetts on July 19, 2012:

Hi Bobbi. Thanks so much for taking the time to read about the Great Horned Owl. I also love the Snowy Owl, they are just stunning. I have a hub on the Snowy Owl if you're interested:

Thanks again for reading and commenting. Bill

Barbara Purvis Hunter from Florida on July 19, 2012:


I love my Snowy Owls since they are so beautiful. However, I did learn something today by reading your hub a few things to be honest.

I will look for your hubs in the future, since I am a country girl at heart and love all animals and birds.


Your Hub Friend,

Bobbi Purvis
