How do Fly bird?

Do you know how birds fly? The structure of the body and wings of birds is suitable for flying in the air. Today we will tell you through this blog what is the scientific reason behind the flight of birds. How do birds use their wings to fly in the air and what challenges do they face.

1.  Lift and  (Curved Type of Wings):-

Birds need light weight to fly because you must have often seen wings or any other thing flying in the air. When the bird opens its wings and rises up and down, which affects the air pressure. How do fly bird?

 

Bernoulli's Law - According to Aerodynamics

When the wind is strong, the air pressure decreases. Similarly, the shape and design of the wings of birds is of curved type which increases the air pressure from bottom to top and this pressure pushes the birds upwards and the pressure of the upper organs is reduced. Due to the curved type of feathers, the upper layer works to cut the air.  How do fly bird?

2. Thrust :

When a bird moves its wings up and down, it cuts the air which reduces the upward pressure in the downward direction and then it pushes the air in the backward direction which produces a momentum force to move the bird forward.

3. (Energy + Body Muscles):

The muscles and nimble body of birds also play an important role in their flight. Their body muscles are very strong, which helps them to flap their wings while flying.

4. Control while :

Birds use their wings very efficiently. When birds have to change their direction while flying, the lift on their body increases. So, to change the angle, birds have to change the speed of the wings as well as the angle of the wings so that they can reduce this lift and change their direction of motion.

5. Challenges/Drag :

When birds fly in the air, the biggest challenge for them is the friction generated by the air. The curved type of wings of birds reduce this friction. When the bird moves its wings up and down, these wings cut the air above and the pressure increases from below which reduces the friction generated in the air. Curved type wings play an important role in reducing the friction generated by the air. How do fly bird?

 

Now you must have understood what is the principle of physics behind the flight of birds.

Frequently Asked Questions (FAQ)

Q1: Why are birds capable of flying while humans not able?

Birds: lightweight body structure, powerful flight muscles, designed wings for lift. Just like having a lighter body which we do not posses and our body does not comply for flying alone without machine like objects (of course machines) [ humans without wings] about lifting.

Question 2: What is lift & how from Where do Birds generate that?

Lift: the vertical upward force that counters gravity and enables avian flight. Birds create lift by pumping their wings to change their shape (concave upper surface and convex lower), which causes differing air pressures above and below the wing(top/below: based on Bernoulli’s principle)[25]

Q3: What are the parts of Bird wings?

Wings of birds are bones, muscles and feathers The Size of the feathers: They range from large and strong, bearing the body weight as in large birds of prey through aerodynamic in smaller lightweight birds such as hummingbirds.

Q4: How birds change their direction while flying?

Birds steer by controlling the angle and speed of their wings In the air, they essentially steer by pushing through thousands of tail feathers and shifting their centre of mass (Body weight.)

Q5: Do all birds flap the same way?

All birds do not fly in the same way because of their wing shapes and intended flight. Hummingbirds can hover, for example whereas Eagles soar close to the ground.
