Their wings and tail
Birds are lightweight because they have hollow bones. This helps them fly.
It helps their aerodynamics, making it easier to fly.

it is feathers

i don't know that is why i asked you
It helps them be light enough to fly
because the drag helps the kite have balance,and it helps the kite fly further and better,and if kite didnt have a drag force they wouldn't have balance when theyre flying and they will lose their capacity to fly,so without drag it is not possible for a kite to fly.
Most birds use their tails for balance and steering while flying. Some use them to show off and attract mates. For birds that can't fly, the tail could just be for balance while running like with the ostrich.
It is not only birds that fly. Bats fly and they are not birds.
birds have strong chest muscles and lightweight bones, which enables them to fly. Their feathers, too, are lightweight, which helps them fly. During flight the birds feathers compress, giving it a more streamlined shape which helps it fly faster. Flight takes up a lot of energy, and birds must eat up to 30% of their body weight each day.
It's wings and the bone structure in them help the eagle, and all birds actually, to fly.
