Great Migrations

Migrations are ticking clocks: animals must move or die, driven by changing seasons and climates. They race to reach their destinations before it's too late to breed, feed or simply stay alive.

Every migration is an epic journey, driven largely by hunger. Every day, trillions of creatures, from microscopic plankton to rare desert elephants face arduous journeys in search of greener pastures.

Witness awe-inspiring stories of species' need to reproduce such as stunning footage of flying foxes soaring across the skies with their young wrapped in their wings and the remarkable breeding behaviours of elephant seals in the Falkland Islands. For the first time in nearly 30 years, see the white-eared kob performing a deadly mating ritual in Sudan.
