Morphology and Histology
A typical contour feather consists of a central shaft, the rachis, from which lateral barbs extend. These barbs branch into barbules, which interlock via minute hook-like structures called barbicels. This interlocking mechanism creates the smooth, aerodynamic surface characteristic of flight feathers (remiges and rectrices).
