Pied Robin?

I took this for a Robin even though it had patches of white throughout its wings and tail. Perhaps I'm wrong, or perhaps it's a Robin afflicted with leucism, which I've read is relatively rare and a bummer because these individuals are less likely to find a mate and avoid predators. I saw a sparrow with an uncharacteristic white wing as well last fall, so perhaps this condition is not so rare in Brooklyn. Here's the sparrow, and another oddball Robin.
