Quick answer
Great Horned Owls (Bubo virginianus) typically live around 10–15 years in the wild. Wild averages fall when predation, disease, or habitat loss rise; managed populations can live longer with stable food and veterinary care.
Key takeaway
Great Horned Owls (Bubo virginianus) typically live around 10–15 years in the wild. Wild averages fall when predation, disease, or habitat loss rise; managed populations can live longer with stable food and veterinary care.
Great Horned Owl lifespan in the wild
Field and museum records place most great horned owls near 10–15 years in the wild. That figure blends ages at death across regions, so treat it as a planning range. Body size (about 1.4 kg) and risk lifestyle both shape the average.
What shortens great horned owl lives
Predation, infectious disease, injury, food shortages, and habitat fragmentation cut survival. Roadkill and human conflict matter wherever great horned owls share landscapes with people.
What helps great horned owls live longer
Connected habitat, low chronic stress, and reliable food support longevity. For captive or domestic relatives, species-correct diet and veterinary screening matter more than generic “pet” advice.
Great Horned Owl life stages
Juveniles usually face higher mortality than prime adults. Older animals may move less, show dental wear, or lose body condition — useful signs when ageing great horned owls in the field.
The tufts and the hoot
The "horns" are not ears but tufts of feathers that may help with camouflage and communication; the owl's actual ears are hidden at the sides of its head and are set unevenly to pinpoint sound. Its deep, soft "hoo-hoo-hoo" is a classic sound of the night and is often the call people picture when they imagine an owl.
Habitat and range
Great horned owls are found from the Arctic edge of North America down through Central and South America, living in almost every habitat, including forests, deserts, swamps, farmland, and city parks. This adaptability and their broad diet make them one of the most widespread and successful owls in the New World.
