Now, how does a bird fly?

– Birds fly with the help of their wings. When

the bird has to fly they lift itself up in the air

by flapping its wings.

– There are two ways in which the wings move:

– Upstroke – The wings move upward and

backward in upstroke.

– Downstroke – The wings move downward

and forward in a downstroke.

– When the bird has to land, it spreads out its

wings and glides down smoothly without

much flapping.
