Downy feathers beneath provide cushioning. An interactive tutorial from the Cornell Lab of Ornithology learn & teach about feathers & bird science. The individual feathers in the wings and tail play important roles in controlling flight.Contour feathers are not uniformly distributed on the skin of the bird except in some groups such as the The colors of feathers are produced by pigments, by microscopic structures that can In some birds, feather colors may be created, or altered, by secretions from the The reds, orange and yellow colors of many feathers are caused by various carotenoids. If you were in the woods, and the feather is larger than six inches, it probably came from a hawk, an owl, or perhaps a game bird, such as a wild turkey.
