Forced to accept that intensive farming on the heavy clay of their land at Knepp was economically unsustainable, Isabella Tree and her husband, Charlie Burrell, made a spectacular leap of faith: they decided to step back and let nature take over. Thanks to the introduction of free-roaming cattle, ponies, pigs and deer - proxies of the large animals that once roamed Britain - the 3,500 acre project has seen extraordinary increases in wildlife numbers and diversity in little over a decade.

Whales are among the largest, most intelligent, deepest diving species to have ever lived on our planet. We have hunted them for thousands of years and scratched their icons into our mythologies. They simultaneously fill us with waves of terror, awe and affection - yet we know hardly anything about them. Whales tend to enter our awareness only when they die, struck by a ship or stranded in the surf. They evolved from land-roaming, doglike creatures into animals that move like fish and breathe like us and can grow to 300,000 pounds, live 200 years and roam entire ocean basins. Yet despite centuries of observing whales, we know little about their evolutionary past.

The sun sinks over the Rio Grande, the mountains around it glow orange, and the world slows down. The Mexican free-tailed bats inside the Jornada Cave are just starting to stretch and murmur. In this episode, we visit the nursery where all the baby bats stay together, and we accompany a new mother as she journeys into the sky with the rest of her crew for a night of hunting bugs via echolocation.

In all animals, mating is a deal. But few creatures behave as if sex is a simple transaction. Many treat it with reverence, suspicion, angst and violence. In the case of the Black Grouse, the bird at the center of Matt Ridley’s investigation, the males dance and sing for hours a day, for several exhausting months, in an exhausting and sometimes deadly ritual called a ‘lek’. To prepare for the ordeal, they grow, preen and display fancy, twisted, bold-colored feathers.

Ever wonder how to tell if a moose is about to subtract you? Curious why you should be terrified of cassowaries, the “velociraptor that time forgot?” Questioning whether that cute baby hippo is actually a homicidal maniac in the making? Yeah, so was Mamadou Ndiaye . . . and now he's got your answers. 100 Animals That Can F--king End You is the ultimate countdown to merk by animal, featuring everything from tiny bugs that can turn you into a hashtag to animals so massive they can murder you by accident.

An Immense World will take us on an insider's tour of the natural world by describing the biology, physics and chemistry animals use to perceive it. We may lack some of their senses, but our own super-sense lies in our ability to understand theirs. And in the face of the largest extinction event since the meteor that killed the dinosaurs, our only hope of saving other species is bound up with our ability to see what they see, and feel what they feel.

Most of us are aware of the hive mind—the power of bees as an amazing collective. But do we know how uniquely intelligent bees are as individuals? In The Mind of a Bee, Lars Chittka draws from decades of research, including his own pioneering work, to argue that bees have remarkable cognitive abilities. He shows that they are profoundly smart, have distinct personalities, can recognize flowers and human faces, exhibit basic emotions, count, use simple tools, solve problems, and learn by observing others. They may even possess consciousness.

Ants number in the ten quadrillions, and they have been here since the Jurassic era. Inside an anthill, you'll find high drama worthy of a royal court; and between colonies, high-stakes geopolitical intrigue is afoot. Just like us, ants grow crops, raise livestock, tend their young and infirm, and make vaccines. And, just like us, ants have a dark side: They wage war, despoil environments, and enslave rivals - but also rebel against their oppressors.

A unique biography of a homeless man and a complete portrait of the hidden underclass. ‘So here it is, my attempt at the story of Stuart Shorter, thief, hostage taker, psycho and sociopath street raconteur, my spy on how the British chaotic underclass spend their troubled days at the beginning of this century: a man with an important life. I wish I could have presented it to Stuart before he stepped in front of the 11.15 train from London to Kings Lynn.’ Stuart Shorter’s brief life was one of turmoil and chaos.

His career as a naturalist and broadcaster has spanned nearly five decades and there are very few places on the globe that he has not visited. In this volume of memoirs David tells stories of the people and animals he has met and the places that he has visited. Over the last 25 years he has established himself as the world's leading Natural History programme maker with several landmark BBC series.

The natural world teems with remarkable conversations, many beyond human hearing range. Scientists are using groundbreaking digital technologies to uncover these astonishing sounds, revealing vibrant communication among our fellow creatures across the Tree of Life. At once meditative and scientific, The Sounds of Life shares fascinating and surprising stories of nonhuman sound, interweaving insights from technological innovation and traditional knowledge.

Investigating the forces that get fish to our dinner tables, Greenberg reveals our damaged relationship with the ocean and its inhabitants. Just three decades ago, nearly everything we ate from the sea was wild. Today, rampant overfishing and an unprecedented biotech revolution have brought us to a point where wild and farmed fish occupy equal parts of a complex marketplace.

For six years Jim and Jamie Dutcher lived intimately with a pack of wolves, gaining their trust as no one has before. In this book the Dutchers reflect on the virtues they observed in wolf society and behavior. Each chapter exemplifies a principle, such as kindness, teamwork, playfulness, respect, curiosity, and compassion. Their heartfelt stories combine into a thought-provoking meditation on the values shared between the human and the animal world.

Brown bears lead deeply cyclical lives. They need to gain sometimes hundreds of pounds during the warmer months to prepare for winter hibernation, a lifestyle that brings them into frequent contact with many other species’ cycles. In this episode, we meander through the Alaska peninsula with a bear and her cubs as she teaches them to hunt salmon at the falls, dig for clams along the coastal mudflats, and use the regional rubbing tree.

The European eel, Anguilla anguilla, is one of the strangest creatures nature ever created. Remarkably little is known about the eel, even today. What we do know is that it’s born as a tiny willow-leaf-shaped larva in the Sargasso Sea, travels on the ocean currents toward the coasts of Europe - a journey of about 4,000 miles that takes at least two years. Upon arrival, it transforms itself into a glass eel and then into a yellow eel before it wanders up into fresh water.

Fennec foxes’ ears can be up to half as long as their bodies. They use them to track movement across the Sahara Desert, including under the sand. In this episode, we follow a fox as he meanders home to his family through the sand dunes as they slowly shift with the wind.

Scientists have long counseled against interpreting animal behavior in terms of human emotions, warning that such anthropomorphizing limits our ability to understand animals as they really are. Yet what are we to make of a female gorilla in a German zoo who spent days mourning the death of her baby? Or a wild female elephant who cared for a younger one after she was injured by a rambunctious teenage male?

The nation's greatest voice, David Attenborough, reads J. A. Baker's extraordinary classic of British nature writing, The Peregrine. J. A. Baker's classic of British nature writing was first published in 1967. Greeted with acclaim, it went on to win the Duff Cooper Prize, the pre-eminent literary prize of the time. Luminaries such as Ted Hughes, Barry Lopez and Andrew Motion have cited it as one of the most important books in 20th-century nature writing.

Platypuses are mammals unlike any other on earth. They lay eggs, ooze milk through their skin, and can sense electricity. In this episode, we travel with a platypus as he moves through his nightly routine on the island of Tasmania. He uses electroreceptors to hunt underwater and does a synchronized swimming courtship ritual with his mate, who then digs a burrow 40 feet deep into the riverbank to nest.

Dogs are a familiar and comforting part of many of our lives. In this episode, we take a walk with a pet xoloitzcuintli, or Mexican hairless dog, as he greets his blocks by smell. Along the way, we learn the backstory of squirrels in U.S. cities and observe the very smart and clean neighborhood raccoon.
