Feathers are a raw material produced by butchering feathered creatures. While in the real world, feathers have traditionally been used for decoration, insulating fill, and writing instruments, there are currently no uses for feathers in Dwarf Fortress, making them a prime candidate for disposal via a refuse pile, incinerator, atom smasher, or the like.
Fortunately, a large number of birds aren't butcherable to begin with. Or unfortunately, for those who prefer modding uses for feathers.
