I would think it's extremely rare. I recently frightened an enormous great horned owl that had a baby in its nest. Rather than attack, the parent flew to another cliff which set off a bunch of smaller birds cawing and swooping at it. It was a huge commotion and the owl was getting dive bombed relentlessly, but the parent owl held its ground, drawing attention away from its baby. I have a ton of respect for that animal.

Owl attacks are actually pretty common.
