Jaguar Adventure with Nigel Marven

Nigel enters the Pantanal via the Transpantaneira Highway - the only way to reach the heart of the Monster Swamp. It's the end of the dry season, and animals are gathering in the shrinking pools next to the road. Nigel hopes that Jaguars will follow the abundant prey...

The jaguars have so far proved elusive. Now Nigel takes a boat to the location of several recent jaguar sightings. He sets up camp on the banks of the Rio Cuiaba, and deploys a crack team of trackers and camera crew to find the big cats.

Nigel's fast becoming a jaguar junkie - and he needs a new fix. He wants to take advantage of this unprecedented opportunity to learn as much as he can about these outrageously beautiful and little understood animals.

Nigel's adventures continue as he encounters more of the Pantanal's astonishing animals - including a giant anteater with a baby on its back, a troop of super-intelligent monkeys, and a colony of over 80 vividly coloured macaws.

It's Nigel's last chance to track down and radio-collar a jaguar. This is gruelling and dangerous work in the swamp's thorny forest - and the jaguar is the Houdini of the natural world.

It's the final episode and, seeking a solution, Nigel tracks down a team of conservationists using a jaguar hunter's techniques to help save "The King of the Pantanal". This offers a way forward for big cats and cowboys - and gives Nigel a unique chance of meeting a jaguar in its jungle home... on foot.
