To be blunt I would give up on that one right now
There simply is not enough resolution in the original to make anything worthwhile out of. You are trying to make something out of image that is not up to it.
Now if you had a small image of say 640x480 pixels that contained mostly the bird and wanted to upsize to a printable files size, say 1600x1200 I would say not a problem and take the advice already offered, but, i'm afraid to say, with this image, you haven't a chance.
