they are light weight and have wings.
Yes, birds with long legs can fly. The only bird with long legs that cant fly is the Ostrich. The only problem is that because of their long legs they are so used to walking, so they don't fly as well as other birds.
To say that birds use wings and feathers to fly, so all birds can fly, would be false. Not all birds can fly. An ostrich is an example of a bird that cannot fly.
They are different species of birds well ducks fly to sorry SOME kind of duks fly

Soft, downy feathers keep birds' bodies toasty and warm. At the same time, the waxy outer ones keep off the rain. More importantly, feathers allow birds to fly. Birds beat their feathered wings to lift off the ground and fly through the air.
humming birds fly so fast because they are so fast
It is not only birds that fly. Bats fly and they are not birds.
Birds need to fly because they are the prey of many animals. They fly mostly when a carnivore is trying to eat them
