Answer:
Birds have evolved not only wings, but many other adaptations that make it possible to fly. First of all, feathers. Feathers provide insulation, waterproofing, and a means to fly — and they're extraordinarily lightweight. Other features also help minimize the pull of gravity, mostly by reducing body weight.
