Feathers are the small soft covering that covers a bird’s body. It is the same as fur. But it is important to understand that it is not called fur. They are called feathers. 

Why? Because fur is entirely different. 

When you look at a dog, it has fur, the hairy surface on the entire body. 

Birds have these little feathers, which feel like cotton in your hand, and these are of different types. There is a difference. Birds have feathers, while animals have fur.

How Do Feathers Help Birds Survive?

If you look at a feather, it has a central hollow shaft with a vane on both sides. The lowest part of the feather is bare on the sides and is called quill. 

The vane has small branches, which you can see. They are very fine, and numerous branches, which are called barbules, make a vane. This is the mechanism of a feather.

It works in several ways to help a bird survive. 

These ways have been discussed here-

  • Wings are not enough for a bird’s flight. The feathers help them in it.
  • Feathers are natural insulators, which preserve the bird’s body heat and help them survive even in extreme environments. It keeps them warm. You can see birds fluffing their feathers. It is a way to trap air, and keep their body warm and regulate body temperature.
  • For large birds like penguins, these feathers help them swim in water using flying motions while the feathers keep them warm. 
  • Birds who live in snowy areas have feathered feet. These feathers keep their feet warm when they take walks around. 
  • These feathers also keep the harsh sun rays at bay, save them from rain, and keep dry in water as they swim.
  • Birds like ducks use their downy feathers, trap the air, and float easily in water without being cold.
  • Feathers also help in hearing. Birds like owls use their feathery face to hunt prey and sense predators.
  • Feathers are like hairs. They are the ones that bear the harsh environment, and thus, the old ones fall, and new feathers take their place. It is called moulting. 
  • Birds condition their feathers regularly. Their skin secretes oil, which birds massage around their feathers and keeps them healthy and shiny. This wax coating also helps to keep them dry as water slips off of them easily. 
  • Many birds use fallen bird feathers to construct nests. They are soft and work as insulators, making a perfect home for infants.
  • Birds have different colored feathers. They use their feathers as camouflage and protect themselves from predators.
