No, one of the feathered dinosaur know how to fly but they give up flying into the ground to find extra food. Bird don't have to be taught to fly because of their ancestors know how to fly. The birds just know their ancestors at once so their are good at flying exept their babies. Their babies need to know how to fly from their mother after having feathers and beeing throw into the ground until it flap it wings.
