Dive deep into South Texas to meet one of America’s most endangered cats: the ocelot. With about 120 known ocelots remaining, the future of the U.S. ocelot population relies on ranchers, scientists and government agencies working together.

While filming the ocelot kittens, filmmaker Ben Masters compares his experience as a new parent to the mother ocelot. He later brings his infant into the field to "help" with camera trapping.

Camera trapping shows more than just data, it also captures this ocelot family's day-to-day behaviors. These filmmakers became the first people ever to see what it takes for a wild American ocelot to raise her young.

Producer Ann Johnson Prum and cinematographer Mark Carroll travel to western Poland to film the nest of the elusive Black Woodpecker. Working with local Biologist Romuald Mikusek they find a nest over 50 feet high. Using climbing gear Mark ascends the tree to mount cameras to film inside and outside the nest.

Cinematographer Mark Carroll takes us up in a crane to show us how he was able to capture feeding and caching behavior at the Acorn Woodpecker’s eyeview at the Hastings Natural History preserve in Carmel California.

Black woodpeckers in Poland are elusive and have rarely been filmed. A pair of these large, imposing birds make a home in a beech tree, where they feed their hungry chicks.

Acorn woodpeckers love to collect acorns and “tattoo” them into the holes they create in trees. Placing these acorns into trees helps this food last throughout the winter. But acorn woodpeckers aren't the only ones who love acorns, so they need to carefully watch their stash.

Get an intimate look at what makes woodpeckers so special. Explore their unique abilities and intimate stories from around the world. Narrated by Paul Giamatti.

The red-backed vole lives beneath the surface of the snow. But there’s one creature that can hear its every move: the great grey owl. And if the owl were not enough of a threat, another predator lurks within the vole's tunnels.

As thousands of belugas arrive, these two polar bears are eager to hunt. However, they have two very different strategies for hunting their prey.

Each small sandpiper must harvest up to 20,000 shrimp while simultaneously avoiding the fastest animal on earth: the peregrine falcon.

Journey from Canada’s Arctic to the boreal forest and discover how polar bears, coastal wolves, lynx and more survive in the North. Timing and seizing opportunity can mean the difference between life and death in this wild and rugged outpost.

Clement Kiragu, a Kenyan trainee cinematographer on "Running with the Beest," recounts the thrills and challenges of working on his first wildlife film. From setting up crucial time-lapses to operating the croc cam, his 64 days in the wilderness are packed with action. Clement also makes the case for Kenyans stepping up to tell the story of their natural world and the wildlife around them.

As the wildebeest migration approaches the river, they know there is danger lurking in the water. Nile crocodiles move towards the herd's crossing points at this time of year and wait for the big arrival.

The wildebeest migration across the river has become a premier tourist attraction in Kenya. While tourism is vital to wildlife conservation, vehicles in these numbers disorient and intimidate the wildebeest’s behavior.

As the wildebeest herd moves north through the border regions with Tanzania, it faces a human threat: an invisible web of wire snares. Poachers sneak across the fenceless border from Tanzania to hunt animals for bush meat, using wire snares.

Witness the great wildebeest migration in East Africa, the most impressive mass movement of land animals on Earth. Travel with two Maasai guides who expose today’s conflict between people and wildlife and share new ideas for co-existence.

"Westward Wings" follows researcher Maggie Hirschauer as she strives to learn more about the monarch butterfly population in western Montana. Maggie’s research opens a window to a world of pollinators and highlights the importance of creating habitat for native pollinators across the Western United States.

When a piece of carrion is spotted on this side of the border, griffon, black, and bearded vultures descend en masse. A strict ranking system applies at the carcass, but one visitor turns up without an invitation.
