Who would in a fight an adult California Condor or Great Horned Owl?

The Great Horned Owl would likely win in a fight against an adult California Condor. While the condor is larger, with a wingspan of up to 9.5 feet, the owl has several advantages. First, the owl has much sharper talons and a stronger grip, which it uses to capture and kill prey. Second, the owl has excellent night vision, while the condor does not. This would give the owl a significant advantage in a fight that took place at night. Finally, the owl is a more aggressive bird, and is more likely to fight to the death.
