the shaft
A feather has a main shaft, called the rachis.
The hollow center line of a feather on a turkey is known as the feather shaft or quill. This central structure provides support and structure to the feather, allowing it to maintain its shape and function effectively for flight and insulation. The hollow nature of the shaft helps reduce weight, making it easier for the turkey to move and fly, despite their large size.
The hard center part of a feather is called the quill or shaft. It provides support and structure to the feather and attaches it to the bird's skin.
A biot is a small part of a feather, specifically referring to the barbs that branch off from the rachis, or central shaft of the feather. These barbs are further divided into smaller structures called barbules, which interlock to create a smooth, aerodynamic surface. Biots play a crucial role in the feather's structure and function, contributing to insulation and flight.
A typical wing feather consists of a central, stiff shaft with the softer vanes on each side. The leading edge of the feather during flight is called the outer vane. The opposite vane is wider than the outer vane and is referred to as the inner vane.
The root of a feather is called the "calamus." It is the hollow shaft at the base of the feather that anchors it to the bird's skin or follicle. The calamus is crucial for the feather's attachment and stability, allowing it to function properly in flight and insulation.
A blood feather on any bird is a feather that still has a blood supply to it. A blood supply is necessary for any feather that is still growing. Once grown out, the blood supply dries up. A feather shaft with a blood supply will be red; a feather shaft with no blood supply will be white.
A quill is not an animal, but rather a hollow shaft of a feather, typically from a bird like a goose or turkey. It is commonly used as a writing implement historically before the invention of the metal dip pen.
In general, a shaft is a long, slender rod or similar object. In engineering, a shaft is a rotating machine element used to transmit power. In anatomy, a shaft refers to the middle part of a long bone.
To fix an arrow feather, first remove any damaged or loose feathers from the shaft using a pair of pliers. Clean the area where the feather will be attached, ensuring there's no residue or glue left. Apply a suitable adhesive, like fletching glue, to the base of the new feather and press it firmly onto the shaft in the correct orientation. Allow it to cure according to the glue manufacturer’s instructions before using the arrow again.
The word quill is a noun meaning feather. It does not have an antonym. Synonyms for quill are plume, down, shaft, and pinion.
