What Are the Individual Parts of a Feather Called? A Detailed Explanation

Learn about the main parts of a feather including the rachis, barbs, barbules, and calamus in this short, informative Q&A.

26 views

Feathers are complex structures made up of several parts: the rachis (central shaft), barbs (extend from the rachis), and barbules (tiny filaments branching off barbs). The calamus is the base of the feather, anchoring it to the bird's skin.

FAQs & Answers

  1. What is the rachis in a feather? The rachis is the central shaft of a feather from which the barbs extend, providing the main support structure.
  2. What are barbs and barbules on a feather? Barbs are the structures that branch off from the rachis, and barbules are tiny filaments that extend from the barbs, helping to interlock and maintain the feather's shape.
  3. What is the calamus of a feather? The calamus is the hollow base part of the feather that anchors it securely to the bird's skin.
  4. How do the parts of a feather work together? The rachis supports the feather, barbs and barbules interlock to create a smooth surface, and the calamus anchors the feather to the bird, enabling flight and insulation.
