This video from the USA says about itself:

Male American Goldfinch chilling on an evergreen tree in the Great Smoky Mountains. These delightful and gregarious songbirds love thistle sock feeders where they can gather in large numbers but it’s always nice to see one out in the open with a nice green contrast. The zoom lens is misleading here – they are some of the smallest birds that come to feeders. This is also a challenging shot technically as the finch is illuminated by direct afternoon sun but the background is in the shade and auto white balance can not handle it giving the bird sort of a whitish color on the back. A lot of defects on film can be simply fixed, but not blown out white!
