Ecologist Rodrigo Medellin set up remote cameras in a bat “nursery.” The cameras capture a behavior that has never been filmed before: a mother giving birth.
To track the migration patterns and distances of the lesser long-nosed bats, Ecologist Rodrigo Medellin coats the bats he catches in harmless UV dust, which they lick off and digest. The glowing dust passes through their system, and by tracking the glowing bat droppings, he can prove how far they’ve flown.
More than three million bats live in the caves of Calakmul. To avoid being eaten by predators, they form a living tornado, or "bat volcano," when they fly. In this whirling mass, it’s almost impossible for their predators to choose a target.
An ecologist tracks the lesser long-nosed bat’s epic migration across Mexico, braving hurricanes, snakes and seas of cockroaches, in order to save the species and the tequila plants they pollinate.
As with any PBS NATURE film, the key to getting the shots is time spent out in the field. Fortunately, for the crew of "Sharks of Hawaii" that meant the tropical islands of Hawaii.
Off the island of Oahu lies an undersea prairie that is home to hundreds of Hawaiian garden eels. Shy creatures found only in Hawaiian waters, these eels only emerge from their burrow to eat zooplankton. They will spend their lifetime in the same spot, trying to avoid the eyes of roaming sharks.
Hawaii is home to the largest hard-shelled sea turtles in the world. It is also the only place in the world where males haul out alongside females when they lay their eggs, and no one knows why.
A school of small mackerel called “Akule” gather in the tens of thousands to form a tight bait ball in order to protect themselves from predators, most notoriously the sharks of Hawaii. But sometimes increasing their profile only attracts more lethal attention.

In a nest barely the size of a golf ball, an Anna’s hummingbird has two healthy chicks almost ready to leave the nest. This is the first time these birds have ever been seen nesting in Big Bend.
Watch the elf owl, the smallest owl in the world, hunt food for its chicks. Despite their small size, these owls are able to tackle prey almost as big and powerful as themselves.
There are many reasons Big Bend is good for bears and this is one of them. A clever bear stumbled upon a woodpecker's large stash of acorns, which he continued to take from for days. Much to the disgust of the acorn woodpecker.
Filmmaker Skip Hobbie discusses his and the crew's experience making "Big Bend: The Wild Frontier of Texas." Hobbie talks about both the challenges and exciting moments while filming the animals of Big Bend, such as beavers and bears.
