I finally saw him dive toward the ground out of a tree, undoubtedly going for a little mouse under the snow. He was about 150-200 feet away. I happened to have a camera with me so I snapped some photos. At that distance, shooting through the trees the auto-focus had trouble. I wish I had my camera with me which has manual focus.
I also shot some video to give you an idea for how far away he was and how hard he was to see and find. It starts out close with the owl in the middle and then zooms out.
