Great Migrations

Every day, millions of creatures are born into a life on the march, on the wing, on the run. From the tiniest butterflies to the largest wildebeest, life itself hinges on these travelers' 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.

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.

Every migration is an epic journey, driven in large part by hunger. From microscopic plankton to rare desert elephants; from predatory bald eagles to luminous jellyfish; our planet is on the move.

When animal behavior confounds scientists, technology now allows them to go places they've never gone before and see things in new levels of detail
