Need help improving this picture please...

[blakjak8]

I took this shot from inside a home and through a window and screen. I know...Get Outside! Without getting detailed...It was not a possibility. How can I clean this picture up? I realize it has many, many limitations. But the lady whoms home I was in Loves Tom (the owl) and has poor eyesight and wheelchair bound. Thought it might be nice for her to have a picture of him. She hears him but cannot see him. My "photo fixing" skills are in their infancy. Thank you very much for any assistance! It is greatly appreciated!! And after writing this...I cannot attach the photo? I must be doing something incorrectly here.
