Chickadees alerted me to this saw-whet owl in Ottawa today. I could hear the chickadees but couldn't see them. Suddenly one of the chickadees came into view. I knew there was an owl in there based on the mobbing calls. Looked down and saw a big spot of fresh white-wash. Now it was a certainty an owl was there. Looked around and up, then saw the owl in the open, wide awake looking down right at me. Chickadees will do that to a small owl.
Unfortunately I did not have a camera. Went back to get it but the owl was well hidden when I returned 20 minutes later. Second saw-whet owl I've seen and photographed in the last week or so.
