Mystery Bird

One of the joys of my slowly developing garden are all the sweet little birds that come to visit. We get Cardinals, Lesser Yellow finches, American gold finch, wrens, woodpeckers, doves, etc. But there's one little guy we can't find in our bird book. He, (or maybe she) has all the markings of an American goldfinch except that his body is pure white! See him in the middle of the photo hiding behind the sock?



He's very shy, so it's hard to get a good picture of him. At first we though it was some kind of gold finch with a mutated gene that made his grayish feathers white. But then we saw TWO! Can they both be mutated?



He has a dusting of yellow on his head, black wing tips and then everything else is white. Snow white.

This is the best picture we got of him. My daughter got it through her bedroom window on the second floor. But it's not as clear as it could be because it's through the glass. Does anyone out there have any idea what this little guy is? Or, any idea where I can find out?

Blessings,
