Yellowstone National Park was once home to an abundance of wild wolves--but park rangers killed the last of their kind in the 1920s. Decades later, the rangers brought them back, with the first wolves arriving from Canada in 1995. This is the incredible true story of one of those wolves. Wolf 8 struggles at first--he is smaller than the other pups, and often bullied--but soon he bonds with an alpha female whose mate was shot. An unusually young alpha...

"In this compelling page-turner, Rick McIntyre profiles one of Yellowstone's most revered alpha males, Wolf 21. Leader of the Druid Peak Pack, Wolf 21 was known for his unwavering bravery, his unusual benevolence (unlike other alphas, he never killed any defeated rival males), and his fierce commitment to his made, the formidable Wolf 42. Wolf 21 and Wolf 42 were attracted to each other the moment they met but Wolf 42's jealous sister interfered viciously...

"The story of a bear named Millie: her life, death, and cubs, and what they reveal about the changing wilds of the American West"--

"Since prehistory, humans and bears have lived side by side. Many cultures around the world viewed bears as a kind of wild counterpart of humans, cloaked in fur. For centuries, bears have been feared and revered, driven away and killed; at the same time, we've reduced them to fluffy toys and cute characters. Why have we misunderstood bears so deeply, and what can we do to repair our connection with them? Drawing on science, history, legend, and colorful...

"There is perhaps no population of U.S. carnivores better studied than the wolves of Yellowstone. These iconic predators were reintroduced to the park in 1995, having been hunted nearly to the brink of extinction. From 1995 to 1997, 41 wild wolves from Canada and northwest Montana were released in to the park, and in the intervening decades scientists followed their every move-from predation to mating to wolf-pup play. The Yellowstone reintroduction...

The influential primatologist draws on renowned primate studies in an exploration of animal emotions that touches on such subjects as expressions, animal sentience, and free will.

"From the top of the world, Hudson Bay looks like an enormous paw print on the torso of the continent, and through a vast network of lakes and rivers, the water in this bay connects to oceans across the globe. Here, at the heart of everything, walks Nanurjuk, or Nanu, one polar bear among the six thousand that traverse the 1.23 million square kilometres of ice and snow covering the bay. For millennia, Nanu's ancestors have roamed this great expanse,...

A dive into the secret lives of whales, from their evolutionary past to today's cutting edge of science. Whales are among the largest, most intelligent, deepest diving species to have ever lived on our planet. They evolved from land-roaming, dog-sized creatures into animals that move like fish, breathe like us, can grow to 300,000 pounds, live 200 years and travel entire ocean basins. Whales fill us with terror, awe, and affection--yet there is still...
