We have Western Screech Owls and Great Horned Owls near me. I have seen Great Horned Owls nests with owlets and a Great Horned Owl alone. One night I was throwing a ball to my dog in the backyard when something swooped down and tried, I think, to attack the ball. I was quite surprised and saw the bird fly into the lower branches of a nearby tree. I could see the eyes of the bird from where I stood and could see it continued to watch the ball as I threw it to my dog. We later figured out it was a Western Screech owl. It was late at night so I didn't get a very good photo of the western screech owl,
but I have several pictures of the Great Horned Owl families.
