The stiff, lightweight, often colorful, keratin structure that is the principal covering of birds. Feathers are composed of a central, hollow quill that attaches to the bird's body. For flight feathers, each side of the quill (vane) has a series of slender, closely spaced barbs that interlock to form a continuous, flat surface. Plume feathers (e.g., ostrich, peacock) are less cohesive with unconnected barbs. Down feathers, obtained from young birds or the undergrowth of adult birds, are soft and lack barbs. Feathers naturally occur in a wide variety of colors pigmented with melanin (black to yellow) and carotenoids (red and yellow). Most birds periodically drop feathers as part of a molting process. Feathers and quills have been used since ancient times for decoration, clothing, masks, and as writing utensils. The fashionable use of feathers in the 19th century directly resulted in several bird preservation laws (e.g. eagle).
