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.

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.

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.

Seashells, stretching from the deep past into the present day, are touchstones leading into fascinating realms of the natural world and cutting-edge science. In Spirals in Time, marine biologist Helen Scales shows how seashells have been sculpted by the fundamental rules of mathematics and evolution; how they gave us color, gems, food, and new medicines.

In Cow Hug Therapy, Ellie Laks recounts the extraordinary journey that started with her first teacher, Buddha—not the religious figure, but a rescued miniature Hereford cow. One evening Buddha wrapped her neck around an exhausted and upset Ellie and transferred a singular form of healing and comfort with an incredible impact. Understanding that this was something to be shared with others, Ellie developed Cow Hug Therapy, a groundbreaking approach to emotional healing that has proved effective for trauma, illness, disabilities, addiction, grief, and stress.

America’s public lands include more than 600 million acres of forests, plains, mountains, wetlands, deserts, and shorelines. In this book, John Leshy, a leading expert in public lands policy, discusses the key political decisions that led to this, beginning at the very founding of the nation. He traces the emergence of a bipartisan political consensus in favor of the national government holding these vast land areas primarily for recreation, education, and conservation of biodiversity and cultural resources.

In the spring of 1983 Terry Tempest Williams learned that her mother was dying of cancer. That same season, The Great Salt Lake began to rise to record heights, threatening the Bear River Migratory Bird Refuge and the herons, owls, and snowy egrets that Williams, a poet and naturalist, had come to gauge her life by. One event was nature at its most random, the other a by-product of rogue technology: Terry's mother, and Terry herself, had been exposed to the fallout of atomic bomb tests in the 1950s.

Published in 1789, The Natural History of Selborne was written by Gilbert White, an English naturalist and clergyman. It comprises White’s letters to fellow naturalists and friends, documenting the flora and fauna of his home town in Hampshire.

Biodiversity, the diversity of life, is not only fascinating and beautiful, it is the engine of all the world's natural cycles, and the source of many of the resources on which humanity depends. Concern about biodiversity conservation is, therefore, not merely the preoccupation of a few enthusiastic naturalists—it is the lifeline business of everybody.

A turkey is the centerpiece of countless Thanksgiving and Christmas dinners. Yet most of us know almost nothing about today's specially bred, commercially produced birds. In this brief book, bestselling author Peter Singer tells their story—and, unfortunately, it's not a happy one. Along the way, he also offers a brief history of the turkey and its consumption, ridicules the annual US presidential "pardon" of a Thanksgiving turkey, and introduces us to "a tremendously handsome, outgoing, and intelligent turkey" named Cornelius. Above all, Singer explains how we can improve our holiday tables.

In Forest Euphoria, Kaishian shows us this making of a scientist and introduces readers to the queerness, literal and otherwise, of all the life around us. Fungi, we learn, commonly have more than two biological sexes—and some as many as twenty-three thousand. Some intersex slugs mutually fire calcium carbonate “love darts” at each other during courtship.

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.

In The Comfort of Crows, Margaret Renkl presents a literary devotional: fifty-two chapters that follow the creatures and plants in her backyard over the course of a year. As we move through the seasons—from a crow spied on New Year’s Day, its resourcefulness and sense of community setting a theme for the year, to the lingering bluebirds of December, revisiting the nest box they used in spring—what develops is a portrait of joy and grief: joy in the ongoing pleasures of the natural world, and grief over winters that end too soon and songbirds that grow fewer and fewer.

In Greenwashed: The New Religion of Climate Guilt, the gloves come off. With biting wit, deep research, and a healthy dose of skepticism, this book dives into the modern environmental movement—unpacking its dogmas, hypocrisies, and unintended consequences. From carbon credits traded like poker chips on Wall Street, to plant-based meats wrapped in plastic and shipped thousands of miles, Greenwashed exposes how marketing, fear, and virtue-signaling have overtaken real solutions.

Humans have long decorated their landscapes, but chalk hill figures are, almost uniquely, a feature of the English downland. This means they are sometimes seen as emblematic of Englishness, celebrated by poets, writers, artists and musicians. The book is a portrait of the places where these figures dominate, bringing in history, politics, literature, music, film and TV, but with a light touch. The Tattooed Hills isn’t a nostalgic elegy for England, instead it uses the figures as a lens through which to explore the land and delves into more troubling undercurrents.

Delivered in his raw and unapologetic yet botanically accurate tone, Joey Santore—the unforgettable host of Crime Pays but Botany Doesn’t—offers an often unsettling view of human-caused ecological destruction and its impact on the natural ecosystems our very lives depend on. The choices of modern civilization have led to a f***ed-up planet, scraped bare and covered in concrete and invasive species.
