Charlene Stephenson, a wildlife photographer based in Alabaster, Alabama, spotted a rare yellow cardinal her backyard on February 17. The American northern cardinal is usually red. The yellow color of this bird is due to a rare mutation, according to Geoffrey Hill, a professor of biology at Auburn University who was quoted in an AL.com report on the bird's sighting. Hill said it was a "one in a million" mutation. (Footage by Charlene Stephenson/Storyful via Getty Images)
