David Attenborough narrates the intimate story of a leopard mother and her two cubs. This very special family must survive in the wilds of Botswana alongside some less-than-friendly neighbours: lions, wild dogs and hyenas. The competition for food is tough, and if they are going to make it they must learn a new skill - they must learn to fish. This is an epic family drama. With them every step of the way is local cameraman Brad Bestelink. Brad's 18-month journey following the lives of these secretive big cats offers a rare glimpse into an otherwise hidden world.

With their charismatic faces and extraordinary head-turning ability, owls are one of our best-loved birds. And yet it's rare to catch more than a glimpse of one in the wild. These mysterious birds haunt our night, floating through the darkness with an eerie silence. But how do they see in the dark? And how do they fly so silently? Through the eyes of two special barn owl chicks and with the help of world leading scientists, Natural World reveals the magic behind owls' superpowers.

A look at the challenges young animals face, from their first steps through to leaving home. For any animal, the early days of life are often the most difficult. Finding food, avoiding predators and generally learning life's essential skills is tough. However, with a little parental guidance growing up can be an adventure. By following some special tiger cubs in India, an adolescent mountain gorilla in Uganda and two nervous polar bear cubs in the high Arctic, the trials and tribulations of growing up wild are revealed.

At the jungle animal hospital in Guatemala, the wards are full of exotic patients, many of them orphans rescued from the illegal pet trade. It is the job of a dedicated team of vets to nurse them back to health.

We follow the team in their busiest year yet as they patch up animals in need, select a troop of spider monkeys for release and prepare a flock of very precious scarlet macaws for freedom.

In the wilds of the Canadian Rocky Mountains, a mother moose tends to her newborn calf. Spring is in full swing, but this far north winter is never far away and, with hungry bears and wolves for neighbours, many challenges lie ahead.

Local cameraman Hugo Kitching knows this only too well, but he is determined to follow the mother and calf through the four seasons. What unfolds is a very intimate story, and when Hugo finds a second moose calf born late in the year, things take an unexpected and dramatic turn.

In the outback of Australia, the world's most famous 'kangaroo mum' is expanding operations. Brolga, aka Kangaroo Dundee, is opening his doors to a whole new bunch of animal characters, including a trio of camels and a southern hairy-nosed wombat called Pete.

The kangaroo joeys are still very much a priority but these days Brolga is sharing maternal duties with his wife Tahnee. With three emu chicks set to move into the family home and the dream of building a wildlife hospital about to become a reality, life in the Australian bush is more hectic than ever before.

In central Australia, Brolga, the world's most famous kangaroo mum, is learning what it takes to look after his extended animal family. The three emu chicks are beginning to wreak havoc, the camels are rapidly outgrowing their backyard enclosure and Pete, the southern hairy-nosed wombat, is proving to be quite a handful.

To help, Brolga's looking to move some of the animals to his 80-acre sanctuary. But, a clash with his old sparring partner, Roger the alpha male kangaroo, has left Brolga on crutches and put all of his plans, including those for the new wildlife hospital, on hold.

The stakes are high, but if they succeed the reward will be a brighter future for an animal we have somehow overlooked.
