What Is the Anatomy of a Feather? Key Parts and Their Functions Explained
Discover the main parts of a feather, including calamus, rachis, barbs, barbules, vane, and afterfeather, and their roles in flight and insulation.
Video transcript
A feather consists of several anatomical parts: 1. Calamus (the hollow shaft at the base), 2. Rachis (the central shaft), 3. Barbs (the parallel fibers extending from the rachis), 4. Barbules (tiny hook-like structures on barbs), 5. Vane (the flat, membrane-like section formed by barbs and barbules), 6. Afterfeather (a smaller feather at the base). This structure provides flight functionality and insulation.
Questions and answers
What are the main parts of a bird’s feather?
The main parts of a feather include the calamus, rachis, barbs, barbules, vane, and afterfeather, each serving distinct structural and functional roles.
How do barbs and barbules contribute to a feather’s function?
Barbs extend from the rachis and are connected by tiny hook-like barbules, which interlock to form the vane, creating a flat surface essential for flight and insulation.
What is the purpose of the afterfeather?
The afterfeather is a smaller feather at the base of the main feather that provides additional insulation to the bird.
