What would happen if birds did not have body feather?
Feathers allow birds to do one of their favorite things: fly. Without their aerodynamically-designed feathers, birds would be waddling around on the ground like the rest of us! Birds are warm-blooded creatures. That means their bodies maintain a healthy temperature to keep them alive.
What material are scales feathers and hair composed of?
Quills, horn, hair, feathers, claws, and baleen are all composed of a fibrous protein called keratin. Keratin is different in structure from collagen, the protein in hide and skin, and has different properties of rigidity, compactness, and hardness. All of these materials (quills, horn, hair, etc.)
What function do feathers and hair have?
Birds such as ducks can coat their feathers in special oils so that they stay dry when in the water. Feathers serve lots of important jobs for birds. Birds, like humans and furry mammalians, are warm-blooded, or homeothermic. Hair, fur, and feathers help them maintain a certain body temperature and stay healthy.
How did hair evolve from scales?
Hair in mammals and feathers in birds have long been known to develop from placodes—patches of thickened skin in embryos that are created by special cells known as columnar cells. In contrast with previous research, the team found that the reptiles in fact formed placodes, as it reports today in Science Advances .
Why birds have feathers instead of fur or scales?
It does this to help trap more air, allowing them to stay warmer. In addition to flight and regulating body temperature, feathers are water resistant, which helps keep birds dry in the rain or in the water. Feathers, especially dark-colored ones, even help protect against the sun.
Why are feathers important to birds?
The complete body of birds is covered with feathers. Feathers serve various purposes. The foremost and the most important function of a feather is that they help in insulation. Feathers also make the body of birds air-light, which makes it easier for them to fly in the air.

How do feathers and hair help different animals?
Most mammals have fur or hair to help keep them warm and protect them from the Sun’s rays. Birds have feathers instead of fur. Feathers are lighter, making it possible for birds to fly. Their feathers also protect them from water and temperature changes.
How do scales help animals to survive?
Scales are usually found on cold-blooded animals – the ones whose body temperature change with that of the surroundings. Compared to fur, scales absorb or dissipate the heat more readily, as needed by these animals. The scales also help the animals in camouflage.
