Learn about Great Horned Owls in Texas
American Barn Owl
The Barn Owl looks ghostly pale, with a heart-shaped white face and dark eyes. It lacks ear tufts. Its back is golden-buff with gray and cinnamon speckles. It has long legs and a buoyant, moth-like flight. It's smaller than the Great Horned, about 13–16 inches long.
Barred Owl
This owl has a round head without ear tufts and soulful dark eyes. Its name comes from the barring pattern on its chest: horizontal bars on the upper breast and vertical streaks below. It is stocky, about 17–20 inches long. It prefers deep forests but has expanded westward.
What Do Owls Sound Like?
Owls use calls to defend territories and attract mates.
- Great Horned Owl: Deep, resonant hoots: "hoo, hoo-hoo, hoo, hoo." Males have a deeper voice than females.
- American Barn Owl: A long, raspy scream or hiss, not a true hoot. It can sound like a shriek.
- Barred Owl: A barking series: "Who cooks for you? Who cooks for you-all?" They also make raucous duets called caterwauling.
Where Do These Owls Live?
Great Horned Owl
It is the ultimate generalist, found across all of North America in forests, deserts, suburbs, and even cities. It avoids only treeless tundra.
American Barn Owl
It needs open habitats like grasslands, deserts, and farms. It relies on cavities for nesting—often in barns, silos, or tree hollows. It is scarce in the far north due to cold winters.
Barred Owl
Originally an eastern forest species, it has expanded westward across the Great Plains via planted shelterbelts. It now competes with the threatened Spotted Owl in the Pacific Northwest.
What Do Owls Eat?
Great Horned Owl
A top predator. It eats rabbits, hares, large birds like geese and herons, and even skunks. It also kills other raptors, including owls. It hunts by perching and ambushing.
American Barn Owl
A rodent specialist. It hunts voles, mice, and rats by flying low over fields. It can catch up to 60 mice in an hour. It swallows prey whole and regurgitates pellets of bones and fur.
Barred Owl
An opportunist. It eats small mammals, but also frogs, fish, and crayfish. It wades into water to catch prey. It caches extra food in tree cavities.
How Do Owls Reproduce?
Owls do not build their own nests. They use abandoned nests, tree cavities, or human structures.
- Great Horned Owl: Nests in winter (January–March) using stick nests from hawks or crows. Clutch: 1–4 eggs.
- American Barn Owl: Can have multiple broods per year if food is plentiful. Clutch size up to 18 eggs. Nests in cavities.
- Barred Owl: Nests in tree cavities in late winter. Clutch: 1–5 eggs. Young "branch" out of the nest before they can fly.
How Do Owls Survive Extreme Climates?
Cold Weather
The Great Horned Owl has thick, insulating feathers and feathered legs. It can withstand harsh winters.
The Barn Owl is poorly adapted to cold. It lacks body fat and has long, sparsely feathered legs. Many die during severe winters.

Hot Deserts
Desert Great Horned Owls are smaller and paler to reflect heat. Barn Owls rely on cool, shaded cavities to escape the heat.
Owls in Culture and Folklore
Owls have always sparked strong reactions.
In many Native American traditions, owls are linked to death and prophecy. The Cherokee used the same word for "witch" and "Great Horned Owl." Warriors wore owl feathers for stealth and courage. Some tribes saw owls as protectors.
European settlers feared the Barn Owl, calling it the "ghost owl" or "demon owl." But farmers soon valued it as a natural rodent controller. Today, many people put up nest boxes to attract Barn Owls for pest control.
Why Owls Matter Today
Owls are indicators of healthy ecosystems. Protecting old-growth forests helps Barred Owls in the east, but their spread west threatens Spotted Owls. Barn Owls need safe nesting sites and reduced rodenticide use. The adaptable Great Horned Owl thrives as long as there are trees and open areas.
Whether you hear a hoot in the night or spot a silent silhouette, take a moment to appreciate these remarkable raptors. They are a vital part of our natural and cultural world.
