I have a great deal of difficulty selectively blurring the background and finishing up with a picture that is believable. This one finished up looking like a cut-n-paste job, but it's not. I use Photoshop CS4. To begin with, I used curves to put a little more contrast into the feathers. Then selected the raven, Inversed the selection, used the blur filter, then removed the selection and sharpened the image. All suggestions, criticisms welcome.
