Hummingbirds are nature's tiny flying marvels

Hummingbirds are truly extreme athletes, beating their wings 80 times per second to create their signature hum. They are the only birds capable of flying backward, upside down, and hovering perfectly still. During courtship, male Anna's hummingbirds dive at speeds faster than a space shuttle relative to their size, experiencing G-forces that would make a human black out instantly.
