What a great experience. That is a beautiful owl, and I bet not too many people have a picture like that to show around! I am glad that you found it, were able (and kind enough) to free it and know someone who is willing to help get it back where it belongs!
Excellent rescue job. I rescued a redtail hawk as a kid ... she had been shot with a bbq'd gun and her wing was injured. I grabbed her barehanded and took her home on horseback. Once she was patched up and released ... she would not leave. But she never bothered a single chicken. I had her for years and she slept in a oak tree...animals know when you are trying to help them.
