I was in the Nevada desert a few years ago camping. It was dusk and I was walking back to camp on a little animal trail. You could barely see. It was black and white and then looking south I could see something with a long wing span slowly flying towards me then about 10 feet away and about 20 feet above a Barn Owl flaps its wings to stay in one place and went back and forth screeching at me looking at me 3 times and turned in the direction it came and flew off until I could not longer them. I took it as a blessing.
