Cuba's Wild Revolution

The very smallest bird on Earth is the Bee Hummingbird, which can be found in the Zapata in Cuba. The remarkable hummingbird is barely larger than the bee it is named after and beats its tiny wings an incredible 80 times a second.

An army of Red land crabs migrates miles as some mothers prepare to lay up to 80,000 eggs apiece. These eggs need to salt water to survive, so the mother's mission is to get to the sea in a journey fraught with danger.

Two months after the mother Green Turtle laid her eggs, the new hatchlings begin their journey to the sea. The newborn turtles hurdle over obstacles as they tumble over the sand toward their new home, as dangerous predators eye their every move.

Cuba piqued the interest of filmmakers who hoped to capture the wildlife of an island widely unknown. To capture intimate details of the nation's wildlife, filmmakers had to explore dark caves full of bats, cockroaches and boas.
