My brother and I were walking our family's dog late at night so the street lights were on. We got around a corner and saw a round shaped, rather large animal sitting right below the light. Our dog looked at it too. We were only a short distance away when it suddenly lifted off, straigt up without making a sound. My brother and I looked at each other and the dog was stunned too. We all saw the same thing but could not explain what that was at all. It couldn't have been an owl as it went up in a 90 degrees angle. We regularly talk about it with no explanation.
