Looks like one to me. Mostly white too. It has a couple of white spots on its neck as well as it whole body.

When I lived in northern VA there was a bunch of them. They ranged from several spots of white to almost pure white. Several of them where like this one.I know they say they are rare but there were maybe 30 -40 of them where I was. I had a pic (very low rez) on a golf course if I can find them.
