Each feather on a bird’s body is a finely tuned structure that serves an important role in the bird’s activities. Feathers help birds fly, but they also help them show off, blend in, stay warm, and keep dry. Some feathers have evolved as specialized airfoils for efficient flight. Others have developed into extreme ornamental forms that may even hinder mobility. Often we can readily tell how a feather functions, but sometimes the role of a feather is mysterious and we need a good scientific study to fill in the picture.
