This guy was found in our courtyard June 15, 2007, healthy and uninjured. We figure he fell from the Wamuchl tree on the side, crossed the roof and fell into the courtyard. He was found by Isabel while sweeping. Some sort of miracle that he wasn't found first by one of the four cats, or two dogs who are hunting this place.
