The quill of a contour feather is hollow. This hollow structure helps keep the feather lightweight while providing strength and flexibility, which is essential for the feather's role in insulation and aerodynamics in birds. The hollow quill also allows for efficient movement and minimizes the energy required for flight.

Birds' contour feathers are responsible for giving them their streamlined shape, which helps reduce drag during flight. Coloration in birds comes from a combination of pigments in the feathers as well as structural colors created by the arrangement of the feathers themselves.
