BARBULE Meaning and
Definition
-
A barbule is a term used in ornithology and biology to describe the individual branches or fibers that form the structure of a bird's feather. Feathers are composed of a central shaft called the rachis, with barbs branching out from either side of it. Each barb further divides into smaller structures known as barbules. These barbules are extremely fine and delicate, featuring tiny hooks or barbicels along their length. It is these miniature hooks that keep the barbules aligned and interlocked, creating a smooth and flat surface on the feather.
Barbules play a crucial role in maintaining the integrity of the feather. They allow feathers to withstand wind and rain while keeping their shape and form. The interlocking barbules also help to create a waterproof barrier, as they prevent water from saturating the feathers and reaching the bird's skin. Additionally, barbules provide insulation by trapping air between them, which helps regulate body temperature in birds.
The structure and arrangement of barbules vary between different species of birds. Some birds have specialized barbules that provide specific functions, such as the powder-down feathers found in some species, which disintegrate into a fine powder to aid in spreading natural oils and maintaining plumage health.
Overall, barbules are integral components of feathers, providing structural support, aiding in flight performance, and contributing to the overall health and well-being of birds.

Etymology of BARBULE
The word "barbule" has its roots in the Middle English word "barbel" or "barble", which originally referred to a beard or whiskers. It ultimately comes from the Latin word "barba", meaning "beard". Over time, the meaning of "barbule" evolved to specifically describe the small, slender, hair-like projections found on the barbs of a feather.
