David Attenborough has a passion for birds' eggs. These remarkable structures nurture new life, protecting it from the outside world at the same time as allowing it to breathe. They are strong enough to withstand the full weight of an incubating parent and weak enough to allow a chick to break free. But how is an egg made? Why are they the shape they are? And perhaps most importantly, why lay an egg at all? Piece by piece, from creation to hatching, David reveals the wonder behind these miracles of nature.

The world's biggest beasts have always captured the imagination. But whilst being big can have its advantages, it also comes with sizeable challenges. Take the world's largest lizard, the Komodo dragon, whose huge appetite means it must take on prey ten times its weight or the tallest animal of them all, the giraffe, who with such a long neck must control immense blood pressure. Nature's biggest beasts must go to extraordinary lengths to thrive. These are their epic survival stories!

The peregrine falcon is the fastest animal on earth - it can reach speeds of over 200mph. But what does it take to be a high-speed record breaker?

Through such groundbreaking experiments and intimate views of these special birds in the wild, the secrets behind these super-fast falcons can finally be revealed.

For the last decade, a team of frontline medics has been fighting to save Borneo's critically endangered orangutans. Armed with cameras, International Animal Rescue has documented their struggle: pulling apes from devastated jungle, giving emergency medical care, rehabilitating and releasing the healthiest orangutans back into the wild. This is both the story of their life-saving work and of how one of our closest wild relatives has been pushed to the brink of extinction. Combining genuine rescue footage with contributions from experts throughout, this documentary looks toward the future and asks what hope remains to save the orangutan.

The endearing pangolin is a little-known scaly mammal. Found in Africa and Asia, these shy creatures have an unfortunate tagline - they are the most poached and illegally trafficked animals in the world. Based in Namibia, conservationist Maria Diekmann rescues and rehabilitates her local pangolins. In a bid to better understand the global issues they are facing, we follow Maria to Vietnam, Thailand and China into the very heart of the crisis, where demand for pangolin products is greatest. In what turns out to be an emotional journey, Maria joins forces with a Chinese megastar to build a campaign to bring awareness to the plight of an animal most people have never even heard of.

The squirrel family is one of the most widespread on earth, so what is the secret to their success? There are squirrels that can glide through the air, outwit rattlesnakes and survive the coldest temperatures of any mammal. We uncover the extraordinary abilities of these cheeky characters, putting their problem solving to the test on a specially designed assault course. We team up with some of the world's top squirrel scientists who are making groundbreaking discoveries - from the fox squirrel who can remember the location of 9,000 nuts to the grey squirrel whose tree-top leaps are the basis of new designs in robotics. We also see the world through the eyes of an orphan red squirrel called Billy, as he grows up and develops all the skills he will need to be released back to the wild. It is time to meet the animal family we should never underestimate - the supersquirrels.

On 12 September 2015, a 30-ton humpback whale breached and landed on Tom Mustill and his friend Charlotte Kinloch as they paddled a sea kayak in Monterey Bay, California. Incredibly, both survived the incident, but the near-death experience haunted documentary maker Tom and left him wondering if the whale was deliberately trying to hurt them. To find the answer, Tom returned to California in 2018 to investigate. Tom meets those who have survived similar hair-raising encounters and the experts who know the whales best. What he discovers raises far bigger questions, not just about what happened that day but also about our relationship with whales and their future alongside us.

David Attenborough reveals that the animal inhabitants of this vast wilderness are every bit as extraordinary as they are bizarre. Unearthly calls of the notorious Tasmanian devil echo through the land, but following them over the course of a year reveals a surprisingly gentle side. In the dry east, rare white wallabies graze on the plains and jack jumper ants build huge nests – these venomous ants are amongst the most dangerous on earth. In the west, where it can rain nearly every day of the year, caves light up with the magical spectacle of thousands of glow-worms, and the trees are 100-metre towering monsters. Rivers are home to the peculiar platypus, and world’s largest freshwater invertebrate, the Tasmanian giant lobster. Miniature penguins come ashore to breed, and as winter approaches, the southern lights dance in the sky. Tasmania’s isolation and unique climate has created a world that is as weird as it is wonderful.

Who are you going to call when beavers are behaving badly? Well, if you live in Jackson Hole, Wyoming, Drew Reed is the go-to 'beaver buster'. Drew works as a wetland conservationist, helping to keep the peace between beavers and people. These busy rodents are incredibly industrious - felling trees and building dams are two of their favourite occupations. This can be good news in the wild, helping create rich habitats for a variety of wildlife, but in backyards it can spell disaster. A beaver is more than capable of bringing down a tree large enough to damage property and their dam building can result in flooded homes. Drew must do what he can to steer beavers away from trouble and stop their so-called bad behaviour.

It opens up the intriguing possibility that a passion for butterflies could help us preserve the landscapes that we love.

It's the largest and most ambitious habitat recreation project ever known: to bring back to life one of the world's greatest marshlands. And it's happening in Iraq. Considered to be the original Garden of Eden, the marshes were once Iraq's wildlife jewel, where man and nature thrived for 5,000 years. But in the 1990s, Saddam Hussein drained these gigantic wetlands and turned them into a desert, destroying a home to thousands of people and millions of birds.

Beginning at the fabulous coral reef of Ningaloo in Western Australia, intrepid marine biologist Mark Meakin attempts to unravel the mysterious wanderings of the biggest fish in the sea. Whale sharks grow to over 12 metres long but are gentle, filter-feeding giants; even Mark's five-year-old son can swim alongside them. Yet no-one knows where they go once they leave Ningaloo's turquoise lagoons. Using satellite tags and photo IDs, Mark tracks them to the white coral beaches of the Seychelles and the tropical jewel of Christmas Island, where bright-red land crabs begin their annual migration. It's hard work, taking in 20 failed satellite tags and countless frustrating dives, before Mark makes a breakthrough which doesn't just add to our understanding of these huge 'dinosaur fish' but offers crucial information about how the whale sharks of Ningaloo can be protected better.

David Attenborough's entertaining romp through the world of monkeys has a serious side: for when we look at monkeys we can see ourselves. From memory to morality, from 'crying wolf' to politics, monkeys are our basic blueprint. Pygmy marmosets 'farm' tree sap; bearded capuchins in Brazil develop a production line for extracting palm nuts; white-faced capuchins in Costa Rica tenderly nurse the victims of battle; and in the Ethiopian highlands a deposed gelada baboon has got the blues.

Another stunning look at the wonders of wildlife as Natural World tonight seeks out the Gharial crocodile. This mighty reptile, which can grow up to 20ft in length and tip the scales at one ton, evolved with the dinosaurs more than 150 million years ago.

Almost every day for the past 25 years, the Viramba troop of yellow baboons have been accompanied by scientists in one of the most extensive primate research projects ever conducted. Researcher Holly Carroll has come to understand the troop, which is controlled by its female members. She discovered that they had established a strict hierarchy in order to keep daily life running smoothly. Kitovu is queen and retains superiority. Old Heshima, humble in her position at the bottom of the ladder, is the guide of the family and leads the troop to the best sources of food and water in the dry season. Young Kibete faces one catastrophe after another with amazing resilience. Interestingly, female offspring automatically inherit their mother's rank.
