Great Horn Owls do not build their own nests; instead, they oftentimes busy deserted nests antecedently employ by mortarboard, triumph, or squirrels. This timeserving doings leave the nest location somewhat exposed to larger, more fast-growing climber.
- Nest location: Nest are often eminent in trees, but they are not invariably absolutely camouflage.
- Circumscribed mobility: Before the owlet memorize to fly, they are completely reliant on the parents for protection.
- Fragrance and noise: Hungry owlets can be noisy, potentially alert nearby piranha to their emplacement.
Common Threats and Predators

The Impact of Human Activity
While discuss the predators of Great Horned Owls, we must acknowledge that humankind are often their outstanding external threat, even if not through direct predation. Habitat loss, pesticide use - which bioaccumulates in the owls' prey - and hit with vehicle or power line claim more lives than any natural predator. The loss of tumid, old-growth tree removes the necessary nesting sites, forcing owls into suboptimal locating where they are more uncovered to raccoons and other mount predators.
