Their association with protection and war can also be found in both Chinese and Native American beliefs. It was thought that the owls had the ability to ward away evil and protect people. Eagle owls in particular were thought to be safe from evil spirits, because the eagle owl was said to devour the spirits. Native Americans associated them with warriors and hunters because of how efficient they are as predators.
Owls were also associated with foretelling the weather. In England, a screeching owl meant that cold weather or a storm was approaching. In other parts of the world, it could mean snow, fair weather, or just a change in the current weather.
