anteaters are unable to fly because they do not have bones like a bird and they do not have feathers or wings to catch the air and glide
If humans fly i think birds will too! A bird utilises the air in flight to give it lift. Forward motion is achieved by beating its wings against the resistance of the air. As the moon has no air a bird would be unable to fly unaided.
Its because fly is both a noun and a verb, so it can be done, and in this case a bird happens to be able to fly. But sadly, bird is a noun and not a verb, so you cannot bird.
I dont think you can fly to the moon on fly like a bird 3 but people say you can on fly like a bird 2.
