Bird Common Not dangerous — still wild
This silent aerial predator hunts primarily small mammals including rabbits, hares, and rodents, but will also take birds, reptiles, and amphibians. With remarkable night vision and powerful talons, it ranks among North America's most successful nocturnal hunters. Incredibly, great horned owls are among the earliest nesting birds, often raising their young weeks before other raptors.
📏 Keep your distance: 25 yards
Stay safe
Maintain 25-yard minimum distance. Observe quietly to avoid disturbing breeding pairs or hunting activity. Owls pose no threat to humans—respect their space as efficient nocturnal predators.
If you encounter one
Observe quietly from at least 25 yards away. Move slowly and avoid sudden movements or loud sounds. Enjoy their presence safely—they're not a threat to humans.
Never feed or approach wildlife — it's dangerous for you and often fatal for them.
