Humpback whales are among the most intelligent animals on Earth. Some scientists believe they might even surpass humans in self-awareness, empathy, and communication skills. In this episode, we swim with a whale as he teams up with other humpbacks to use bubbles to catch fish, rescues a sea lion, and puts his own spin on melodies sung by whales across the Pacific Ocean. This is the world in its natural state, defined by seasons, routines, and cycles. By the time this whale is ready to close one eye and go to sleep, you will be too.

Sloths are the slowest mammals on earth. They can hardly see. They live in rainforests among jaguars, pumas, and countless other predators. Yet they survive. And they do it by being so incredibly slow, and living a life covered in algae. In this episode, we hang with a sloth in the jungle of Costa Rica as he spends a month digesting one single leaf, and we see the symbiosis and collaboration that surrounds him.

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.

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.

Crows have long been the subject of folklore, likely because they’re strikingly similar to humans, leading lives rich in personality, intelligence, and relationships. In this episode, we fly the streets of Seattle with a crow as she grooms her mate, delivers what appears to be a gift, and finally commutes miles away from her territory to gather and chat with thousands of other crows before it’s time to roost for the night.

Elephants are the largest land animals in the world. They are also intensely social and have advanced long-term memories. In this episode, a parade of Asian elephants makes its way through the Sri Lankan forest to a lake for drinks and mud baths, stopping periodically for group naps. The female leading the parade uses infrasonic rumbles—inaudible to humans, but traveling as far as two miles along the surface of the Earth as seismic waves—to invite friends and family around the forest to join her at the reservoir.

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.

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.

To celebrate the 40th anniversary of the book’s first publication, David Attenborough has revisited Life on Earth, completely updating and adding to the original text, taking account of modern scientific discoveries from around the globe....

Both a captivating narrative and a book of environmental and historical significance, American Buffalo tells us as much about ourselves as Americans as it does about the creature who perhaps best of all embodies the American ethos.

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.

How do trees live? Do they feel pain or have awareness of their surroundings? Research is now suggesting trees are capable of much more than we have ever known. In The Hidden Life of Trees, forester Peter Wohlleben puts groundbreaking scientific discoveries into a language everyone can relate to.

Dung beetles might sound dirty, but the ancient Egyptians believed their god took the form of a dung beetle to roll the morning sun across the sky every day. In this episode, we roll with dung beetles around the world as they push their precious dung—often in balls many times larger than they are—over Florida pastures, Armenian highlands, and the vast South African savanna.

Robert Macfarlane brings his glittering style to a profound work of travel writing, reportage, and natural history. Is a River Alive? is a joyful, mind-expanding exploration of an ancient, urgent idea: that rivers are living beings who should be recognized as such in imagination and law. Macfarlane takes listeners on three unforgettable journeys teeming with extraordinary people, stories, and places: to the miraculous cloud-forests and mountain streams of Ecuador, to the wounded creeks and lagoons of India, and to the spectacular wild rivers of Canada.

Traditionally, Americans learned in school that the ancestors of the people who inhabited the Western Hemisphere at the time of Columbus' landing had crossed the Bering Strait 12,000 years ago; existed mainly in small nomadic bands; and lived so lightly on the land that the Americas were, for all practical purposes, still a vast wilderness. But as Charles C. Mann now makes clear, archaeologists and anthropologists have spent the last 30 years proving these and many other long-held assumptions wrong.

The seven rivers in this narrative were chosen because they are major rivers that magnify the common qualities of these great natural arteries that run through civilization. The Nile, Danube, Niger, Mississippi, Ganges, Yangtze, and Thames are all "world rivers" by virtue of the roles they have each played in our shared and conflicted world history.

In Tides: The Science and Spirit of the Ocean, writer, sailor, and surfer Jonathan White takes listeners across the globe to discover the science and spirit of ocean tides. In the Arctic, White shimmies under the ice with an Inuit elder to hunt for mussels in the dark cavities left behind at low tide; in China, he races the Silver Dragon, a 25-foot tidal bore that crashes 80 miles up the Qiantang River; in France, he interviews the monks that live in the tide-wrapped monastery of Mont Saint-Michel; in Chile and Scotland, he investigates the growth of tidal power generation.

When Desert Solitaire was first published in 1968, it became the focus of a nationwide cult. Rude and sensitive. Thought-provoking and mystical. Angry and loving. Both Abbey and this book are all of these and more. Here, the legendary author of The Monkey Wrench Gang, Abbey's Road and many other critically acclaimed books vividly captures the essence of his life during three seasons as a park ranger in southeastern Utah.

If fresh water is to be treasured, the Great Lakes are the mother lode. No bodies of water can compare to them. One of them, Superior, is the largest lake on earth, and the five lakes together contain a fifth of the world's supply of standing fresh water. Their surface area of 95,000 square miles is greater than New York, New Jersey, Connecticut, Massachusetts, Vermont, New Hampshire, and Rhode Island combined. They are so vast that they dominate much of the geography, climate, and history of North America. In one way or another, they affect the lives of tens of millions.

The story of the world's largest, longest, and best-financed scientific expedition of all time, triumphantly successful, gruesomely tragic, and never before fully told. The immense 18th-century scientific journey, variously known as the Second Kamchatka Expedition or the Great Northern Expedition, from St. Petersburg across Siberia to the coast of North America, involved over 3,000 people and cost Peter the Great over one-sixth of his empire's annual revenue.
