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.

What does it take to relocate a herd of wild giraffes in Africa? One man, his family and a band of enthusiastic helpers are about to find out.

That's because these are no ordinary giraffes; they are, in fact, the world's rarest. Any mistake could be costly, not only for the giraffes being moved but also for an entire species.
