Creatures whose lives depend on their ability to get up and go.

Every day, migrating creatures around the world wage incredible journeys; risking it all in pursuit of the one thing more precious than themselves: the creation and caretaking of their precious young-the next generation of global wanderers. From the rocky beaches of the Falkland Islands to the dense forests of Costa Rica and Australia to the desolate savannah of southern Sudan, countless animals now venture forth on timeless journeys, bent on their own survival-and the survival of their species.

In Science of Great Migrations viewers will see how the latest tagging technology helps scientists better understand the movements of creatures great and small; how texting could save a species from extinction; and how mathematical models might be able to predict a herd's survival.

The annual search for greener pastures means life must go on the march. Desperate herds, flocks, mobs and schools wage global searches for sustenance, while hungry predators lie in wait.

Migrations are races against time. Seasons change - freezing temperatures and scorching heat usher in a crisis. Trillions of creatures must dash for safety, running a gauntlet of stealthy predators. Safe havens are vanishing and migrating animals must stay one step ahead of a changing planet.
