I can't believe most people think this creative invention is not real; that it is an animation. I remember in 1971, in NYC, where I lived at the time, street vendors suddenly started selling a plastic bird which had an elastic that you wound up and then it took off and flew by flapping its wings. A man in France had invented, patented, manufactured and sold millions of them. It was quite a sensation, in all the media. The novelty was that no one had EVER invented something that actually flew by flapping wings like a bird. The secret was the oval wing action at the shoulder that allowed the wing to catch air, press it down, and then bring the wing forward without catching the air. The repeated strokes downward allowed the model bird to rise. For thousands of years no one had ever figured it out. If you have ever gone swimming, you get the idea.
