Light microscope footage of a feather from a pigeon (Columba sp.). Bird feathers are made up of hundreds of barbs extending from a central shaft, or rachis. Each barb is branched, into barbules. The barbules contain hooks called barbicels (running from bottom right to centre) that attach to adjacent barbules, holding the feather in a stiff plane. | |
