Feather. This down feather forms part of a bird's insulating underplumage. The feather has a central axis or rachis which bears the flat vane of the feather made up of many slender barbs. Feathers give a bird the ability to fly, as well as providing waterproofing, camouflage, and the colours or shapes for attracting mates.
