What is the end of a bird feather called?
The bare end is called the quill or calamus. The pointy end of the feather is called the inferior umbilicus. This is the hollow opening where when the feather was growing it received nourishment. The portion of the shaft between the two webs of the vane is called the rachis.
What is the function of the feather?
Feathers perform a number of functions for a bird: 1) They provide insulation, body temperature of most birds is maintained at around 40 C; 2) Feathers allow for flight; 3) Feathers control what a bird looks like by supplying the bird with colors.
What is a feather made of?
Feathers are made of lightweight material called keratin just like our fingernails. Muscles attached to the base of each one allow the bird to move it around. Feathers have to handle a lot of wear and tear, so each year birds grow a new set to replace the old ones. This is called moulting.
What are the parts of the feather of a bird?
Feather Anatomy The parts of a feather you can see with the unaided eye are the rachis, vane, afterfeather, barbs, downy barbs and the hollow shaft. There are also tiny parts called barbules and hooklets that help hold the barbs together and give the feather its shape.
Why do birds have feathers?

How is a feather created?
Feathers develop from the dermal papillae. Feathers begin to form from feather follicles, which are invaginations starting in the epidermis down to the dermis. It is in the dermis that the follicle and the pulp cavity begin to form the feather. The pulp cavity is the space that contains the feather follicle.

What is feather in biology?
A feather is a growth from the skin, much like a hair, that forms the plumage of birds. It is an integral part of a bird's biology, both physically and behaviorally. They have evolved over millions of years to be ideally adapted to benefit birds in a range of functions such as flight, insulation and protection.
