How Tall Is A Great Horned Owl

Last Updated on April 22, 2023 by naime

Great horned owls are one of the most popular owl species in North America. Known for their piercing yellow eyes, feather tufts on their heads that resemble horns, and deep hoots heard during the night, these majestic creatures have captured the attention of bird enthusiasts everywhere. One question frequently asked is: how tall can a great horned owl grow?

To answer this question accurately, it’s important to note that height varies depending on factors such as age, gender, and geographic location. However, on average, adult great horned owls stand about 18-25 inches (45-63 cm) tall from head to toe. Interestingly enough, female great horned owls tend to be slightly larger than males – measuring up to 25 inches in height compared to males’ 23 inches. Now let’s dive deeper into what makes up this impressive creature’s physical stature!

Understanding Great Horned Owls’ Physical Characteristics

Great Horned Owls are one of the largest and most recognizable species of owls in North America. These birds can grow to be up to 2 feet tall, with a wingspan that stretches over 4 feet wide. Their size is attributed to their large feather mass and muscular build, making them formidable predators in their environment.

The Great Horned Owl’s trademark feature is its ear tufts or "horns." These tufts are not actually ears but rather just feathers that help camouflage the owl by breaking up its silhouette against tree bark. The owl does have actual ears located on either side of the head, which are covered by specialized feathers for sound insulation.

Great Horned Owls also possess sharp talons that they use to catch their prey. They have four talons per foot, two facing forward and two facing backward, allowing them to grasp onto prey securely while flying through dense forests or fields at high speeds.

In addition to their impressive physical characteristics, Great Horned Owls’ plumage varies depending on geography and climate. Birds from northern regions tend to have lighter-colored feathers than those found further south. This variation helps provide better camouflage against the different environments these birds inhabit throughout North America.

Factors That Influence Owl Height

I’m an ornithologist researching factors that influence owl height, and I’m particularly interested in how species, diet, age, habitat, climate, and behaviour all play a role. For instance, different species of owls can vary greatly in size, so the species of owl is a major factor in its height. Diet is also important, as owls that eat a lot of large prey will likely be larger than those with a more varied diet. Age is also important, as younger owls may not yet have reached their full height. Finally, habitat, climate, and behaviour can also all come into play.


As an ornithologist, it is important to study the different owl species that exist in order to understand how they differ in terms of height. The Great Horned Owl (Bubo virginianus) is one of the most well-known and common species found throughout North America. This large bird stands at an average height of 18-25 inches (46-63 cm) tall, with a wingspan ranging from 3.3 – 4.8 feet (1-1.5 meters).

However, there are other owl species that dwarf even the Great Horned Owl in terms of size. For example, the Eurasian Eagle Owl (Bubo bubo) can reach up to 30 inches (75 cm) in height and has a wingspan of over six feet (2 meters). Similarly, the Blakiston’s Fish Owl (Bubo blakistoni), found primarily in Russia and Japan, can stand up to three feet tall (90 cm).

It’s worth noting that while these larger owl species may be impressive in size, their habitats and diets also play a significant role in their growth and stature. Owls living in colder climates often have thicker feathering than those living in warmer areas, which can add both weight and bulkiness to their overall appearance.

In conclusion, studying owl species provides crucial insight into understanding how factors such as habitat and diet influence their physical characteristics like height. While the Great Horned Owl is considered tall compared to many other bird species, it still pales in comparison to some of its larger cousins around the world. As ornithologists continue researching these fascinating creatures, we will undoubtedly uncover more insights into what makes them unique and awe-inspiring animals.


As an ornithologist, it is essential to study different factors that influence the physical characteristics of owl species. One such factor is their diet. Owls are known for being excellent hunters and feed on a variety of prey, including rodents, insects, fish, and even other birds.

The type of prey consumed by owls can significantly impact their growth and size. For instance, larger prey items like rabbits or hares require more energy to hunt and consume than smaller prey like mice. As a result, owls that primarily feed on large prey tend to be larger in size compared to those that consume smaller prey.

Moreover, the availability of food sources also plays a crucial role in determining an owl’s height. In areas with abundant food resources, owls have access to a consistent supply of nutrients necessary for healthy growth and development. On the other hand, limited food availability may lead to stunted growth or decreased body mass in some species.

By analyzing the types and availability of prey consumed by various owl populations worldwide, we can gain a better understanding of how these magnificent creatures adapt to survive in different environments.

Average Height Of Adult Great Horned Owls

After discussing the various factors that can influence owl height, it’s time to delve into the actual measurements of adult great horned owls. Brace yourselves, because you’re about to learn just how massive these birds truly are.

The average height of an adult male great horned owl is around 22 inches (56 cm), while females tend to be slightly larger at 25 inches (64 cm). However, these numbers don’t quite do justice to just how intimidating these creatures can appear when perched on a tree limb or swooping through the air in pursuit of prey.

To give you a better sense of their size, here are some facts about adult great horned owls that might surprise you:

  • Their wingspan can reach up to 5 feet (1.5 meters) wide!
  • They have sharp talons measuring up to 2 inches long.
  • Adult males weigh an average of 3 pounds (1.4 kg), while females tip the scales at around 4 pounds (1.8 kg).
  • Great horned owls have large heads with distinctive ear tufts and striking yellow eyes.
  • These raptors are known for their deep hooting calls, which can carry over long distances.

As ornithologists continue to study great horned owls and other avian species, we gain a greater appreciation for the incredible diversity and complexity within our natural world.

Whether you’re an amateur birdwatcher or a seasoned scientist, there’s always something new to learn from studying these awe-inspiring creatures.

Gender Differences In Height

Male great horned owls typically range in height from 18-25 inches, while females are generally larger and can reach up to 25-28 inches. This difference in size is known as sexual dimorphism and is common among many bird species. The reason for this size discrepancy is thought to be related to the different roles that males and females play in reproduction.

In most bird species, males are responsible for attracting mates through displays of strength and vigor. Larger body size may give male great horned owls an advantage in competing with other males for access to females during breeding season. Female great horned owls, on the other hand, have the important task of incubating eggs and caring for young chicks. A larger body size may provide greater protection against predators or harsh weather conditions when nesting.

It’s worth noting that not all great horned owls will conform strictly to these average heights, as there is variability within populations due to factors such as age, nutrition, and geographic location. However, studies have consistently shown that female great horned owls tend to be larger than males overall.

Understanding gender differences in height can provide valuable insights into the behavior and ecology of a species. By knowing how physical traits relate to mating strategies and reproductive success, we can better protect these magnificent birds and their habitats for generations to come.
