Red-Shouldered Hawk in Snow

Saw this guy (or gal) landed on our fence and grabbed my camera. I had it laying nearby hoping to get a photo of some bluebirds in contrast to the snow, but this guy will do. This was shot thru a (likely dirty) window using my 70-200m F4 lens. It's been cropped a little, along with a little bump in saturation and a little curve (using the very simple Canon Digital Photo Professional).
