Aberrant Plumaged Goldfinch

[youtube]http://www.youtube.com/watch?v=QzESPoTl_LU[/youtube] That odd little American goldfinch is still hanging around, he showed up this morning on my sunflower feeder while I was making breakfast and I tried to grab a quick video (apologize for the Wayne Newton in the background).  I don't think that cap is ever going to grow in, it's almost time for the male goldfinches to return to their winter plumage.  I wonder if he will stick out in his winter plumage?
