I have a bird-feeder outside my cabin in Blue Ridge, Georgia and normally I only see Tufted Titmouse (see below) and Carolina Chickadees. But the other day I noticed a flash of yellow fly-by the window and quickly looked outside to see an American Goldfinch sitting in a nearby tree. Unfortunately, it was a cloudy and windy day so the pictures are not the greatest due to higher grain but there is still enough detail to see it.

You can see in this picture the wind blowing the head feathers.
