Ball State Screech Owl

Back in November '05 I saw an Eastern Screech Owl along Christie Woods at Ball State. (Link to post) Monday, I was walking by the same tree, and there he was. I had checked earlier in the afternoon when I was coming in, but I didn't see him. He might have been down inside the tree then. I did not have my camera with me, so I went and bought a disposable. I wish I had my own camera, but I love pictures of owls. He just sat there and slept, occasionally peeking at me. I probably watched him for a half hour. Check out the earlier post. Do you think it is the same owl? I don't know the lifespan for Screeches, but I would guess it could be over 2 years.
