feather duster

:  any of the light, horny, epidermal outgrowths that form the external covering of the body of birds ◆Feathers include the smaller down feathers and the larger contour and flight feathers. Larger feathers consist of a shaft (rachis) bearing branches (barbs) which bear smaller branches (barbules). These smaller branches bear tiny hook-bearing processes (barbicels) which interlock with the barbules of an adjacent barb to link the barbs into a continuous stiff vane . Down feathers lack barbules, resulting in fluffy feathers which provide insulation below the contour feathers.
