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
well, a bird that cant fly has a larger body mass than one that can
So the birds can protect and stay alive.
its so if a enemy comes near them they can fly a way

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
so they can fly
