What are the functions of different types of feathers?

Most birds are covered in feathers, as feathers perform many important functions for the bird’s body.

Pen functions:

– Flight and tail feathers allow the bird to fly and control the trajectory of its movement, direct itself in one direction or another.

– Down feathers allow the bird to retain its body heat and not lose it.

– Threaded feathers have a tactile function.

– All types of feathers that cover the bird also perform a protective function, protecting it from external factors.
