Barn Owl vs Great Horned Owl (Tyto alba vs Bubo virginianus): The Complete Backyard Identification Guide
Quick Answer: The Fastest Way to Tell Them Apart
The ghost and the tiger of the night. Three rules:
- Head silhouette: smooth, round, tuftless with a heart-shaped face = Barn Owl; great ear tufts (“horns”) on a massive head = Great Horned Owl.
- Plumage: golden-buff above, ghost-white below = Barn Owl; mottled gray-brown with a white throat bib = Great Horned.
- Voice: raspy screech = Barn Owl; deep, booming “hoo-hoo hooooo hoo-hoo” = Great Horned.

| Bill Shape | Small, pale, hidden in facial feathers | Black, hooked |
| Tail | Short, buff-barred | Short, barred |
| Core Range | Nearly worldwide — open farmland, grassland and towns across most of the US | All of the Americas — every habitat from desert to city park |
| Migration | Non-migratory resident | Non-migratory resident |
| Feeder Presence | Never visits feeders; hunts mice and voles over open ground at night | Never visits feeders; hunts rabbits, skunks and even other raptors at night |
| Favorite Foods | Rodents — mice, voles, rats — caught by sound in total darkness | Mammals up to rabbit and skunk size, birds, reptiles |
| Song KEY | No hoot at all — a raspy, drawn-out screech “shreee” | Deep, booming “hoo-hoo hooooo hoo-hoo” hoots |

Song & Call Comparison
Barn Owl
Voice: a raspy, drawn-out screech shreee — never a hoot.
At the nest: hisses, clicks and the famous nestling “snore”.
Great Horned Owl
Song: deep, booming hoo-hoo hooooo hoo-hoo.
Calls: screams, barks and hisses near the nest.
Range & Seasonal Presence
The Barn Owl hunts open country across most of the US — farmland, grassland, town edges.
The Great Horned Owl lives everywhere in the Americas — desert, forest, tundra edge and city park. It is the most widespread large owl on the continent, and it is the Barn Owl’s occasional predator as well as its neighbor.
Feeder Behavior & Favorite Foods
- Neither visits feeders — both hunt live prey.
- Barn Owl: nest boxes over open hunting country; thousands of rodents taken per family each year.
- Great Horned Owl: big wooded lots host hunting visits; it nests in midwinter in old hawk nests — listen for hooting duets in December and January.
- Caution: Great Horneds take skunks, rabbits and occasionally small pets at night — keep small animals indoors; never use rodent poison.
Temperament & Flock Behavior
Barn Owls are silent specialists, ghosting over fields and shrieking when cornered at the roost.
Great Horned Owls are fearless generalists — the “tiger of the air”, willing to hunt almost anything and to defend a nest against humans in late winter.
