Nature S35E01 - Super Hummingbirds

Though high-speed camerawork and breakthrough new science, enter the fast-paced world of hummingbirds as never before. Speed is their middle name. They possess natural super powers that enable them to fly backwards and upside-down and float in mid-air. And for the first time, see them mate, lay eggs, fight and raise families in intimate detail. They are great athletes, tender mothers and brave combatants, up for any challenge. They are the smallest, most brilliant birds on earth.
