The most I could get in one shot was four of them. They were doing their best to look like part of the tree.
They did not move, except to follow me with their eyes. When I moved around back of them, they tipped over to keep me in sight. They stayed for close to 30 minutes. I ran into the house to load the photos on the computer and when I went back out, they were gone. I believe they are Western Screech Owls. At least that's the closest I could come with my bird book.
