Great horned owl

The Great horned owl (Bubo virginianus) is a powerful avian predator classified within the order Strigiformes and the family Strigidae. While primarily recognized as a wild species, it can represent a significant challenge for small-scale livestock and poultry farms due to its predatory behavior.

The species does not consume crops, making it a predator rather than a traditional botanical pest. However, the economic damage caused by the loss of domestic poultry and rabbits leads farmers to categorize it as a nuisance that requires active mitigation to protect farm assets.

Regarding its biology, the Great horned owl is highly territorial and typically active from dusk until dawn. Their breeding cycle starts in late winter or early spring, a time when the owls are most aggressive in securing food for their young, often leading them to hunt within the boundaries of rural properties.

The harm is characterized by nocturnal raids on open-range livestock environments. Aside from direct predation, the presence of such a large apex predator induces significant stress in domestic animals, which can result in reduced growth rates, lower egg production, and increased susceptibility to diseases among the farm stock.

Effective management and protection strategies for farms include several non-lethal deterrent methods:

• Installation of heavy-duty wire netting over all poultry enclosures.
• Implementation of motion-activated floodlights to disrupt night hunting.
• Deployment of realistic predator decoys that are moved periodically.
• Use of acoustic deterrents that mimic the calls of competing raptors.
