White-headed Red-wing Blackbird?

Last week I went down to Hatteras (on a very cold day) to chase a Mew Gull that had been reported down there the day before. I never found it, but I stopped by Pea Island on the way home and found this slightly leucistic Red-winged Blackbird. He was sitting on top of some wax myrtle and singing away. These Blackbirds are really common here on the OBX, but I've never seen one that looked like this before. Right below him you can see a female Red-winged Blackbird. She's really streaky like a sparrow and probably shouldn't be called a "blackbird".
