Animals Up Close with Bertie Gregory

Bertie searches the wilderness of Patagonia in southern Chile, hoping to find and film a female Puma that he first met four years ago when she was just a cub. When he finds her, she has two cubs of her own which she must feed and protect from the many dangers of this harsh mountain landscape.

Bertie and the team cross the infamous Drake Passage, the roughest stretch of ocean on Earth, to reach Antarctica, where they witness and film the staggering intelligence and adaptability of a group of killer whales. Known as B1's, they use an extraordinary strategy to hunt seals resting on ice. Working as a team, they create a powerful wave to push the seals into the water. Bertie wants to find out why the B1 population is declining and film the other surprising ways they catch prey in their rapidly changing world.

Bertie travels to Botswana to film one of the planet's most successful land predators: the African wild dog. Despite their hunting super skills, wild dog population numbers are dramatically declining. By following a family pack with 14 young pups, he wants to find out what it will take for the next generation of these endangered predators to survive. They face threats from lions, hyenas and elephants, and it's clear that these African wild dogs don't go down without a fight.

Bertie travels to the remote islands of the Galapagos to find and film three rare animal behaviors seen nowhere else on the Earth, each with an extreme challenge. He will face huge Pacific waves, shark-infested waters, and ultra-fast hunting sea lions on the rugged Galapagos coast, teaching Bertie how these unique animals survive in a rapidly changing world.

Bertie is on a stakeout deep in the jungles of the Central African Republic, searching for the biggest and most secretive of the forest elephants: the tuskers, huge males with tusks that reach down to the floor. Working with a specialist camera team and local elephant trackers, he sets up a filming HQ high in the rainforest canopy.

Bertie travels to Indonesia to dive amongst some of the most exquisite coral reefs left on Earth, hoping to catch a glimpse of one of the reef's most elusive predators: the mysterious devil ray. His best chance of finding one is to track down a huge annual spectacular, an anchovy feeding frenzy.
