Great Migrations

Borne of suffering, desperation, and starvation, every migration is a death-defying journey, filled with countless obstacles. Science of Great Migrations will go behind breathtaking images of migration and show how scientists learn from and study these magnificent spectacles of nature. The iconic migration of wildebeest in the Serengeti; the 1,800 mile flight path of the monarch butterfly; the two-month pilgrimage of the southern elephant seal off Patagonia; and the perilous journey of African elephants in Mali together give scientists a look into this dangerous world of migration. Advances in scientific technology and data collection are revealing a new understanding of animal decision-making, swarm dynamics and the inner workings of a herd, flock or pod.

Every migration is an epic journey, driven in large part by hunger. Every day, trillions of creatures are moving in search of greener pastures. From microscopic plankton to rare desert elephants; from predatory bald eagles to luminous jellyfish; from ravenous Great White Sharks to lightning quick peregrine falcons; our planet is on the move. Countless creatures on timeless journeys, moving in numbers, surviving as one.

Migrations are ticking clocks: every day, countless animals must move or die, driven by changing seasons, and a changing climate; they are racing to reach their destination, before it's too late, to breed, feed or simply stay alive. From the ever changing Arctic ice floes to the salt pans of Botswana, trillions of creatures are compelled to journey - for the sake of their own survival and their legacy. But for animals ranging from walruses to whale sharks, zebras to orangutans, pronghorn to plankton -- every day is a race against time.

Starting in 2007, National Geographic crews dispersed all over the planet to film the most amazing and unique animal migration stories ever told. Over the 2 years, the crew spent 350 hours in trees, 500 hours in blinds and 400 hours underwater. This behind-the-scenes story takes you to the depths of the sea and the far corners of the earth as you experience the dangers, difficulties and adventures of a National Geographic Cameraman.

Great Migrations: Rhythm of Life is an unprecedented National Geographic Film. This film is a unique presentation of the very best footage and spectacular orchestral score of NatGeo's Great Migrations Television Event. The film brings together images from around the world, filmed over 3 years, resulting in a completely unique, narration-free, musical journey around the world. Great Migrations: Rhythm of Life is a breathtaking ride on the tailwinds of billions of creatures marching, swimming and flying across the planet on death-defying journeys.
