Available in PDF, EPUB and Kindle. Book excerpt: When and where did the ancestors of modern birds evolve? What enabled them to survive the meteoric impact that wiped out the dinosaurs? How did these early birds spread across the globe and give rise to the 10,600-plus species we recognise today ― from the largest ratites to the smallest hummingbirds? Based on the latest scientific discoveries and enriched by personal observations, The Ascent of Birds sets out to answer these fundamental questions. The Ascent of Birds is divided into self-contained chapters, or stories, that collectively encompass the evolution of modern birds from their origins in Gondwana, over 100 million years ago, to the present day. The stories are arranged in chronological order, from tinamous to tanagers, and describe the many dispersal and speciation events that underpin the world's 10,600-plus species. Although each chapter is spearheaded by a named bird and focuses on a specific evolutionary mechanism, the narrative will often explore the relevance of such events and processes to evolution in general. The book starts with The Tinamou’s Story, which explains the presence of flightless birds in South America, Africa, and Australasia, and dispels the cherished role of continental drift as an explanation for their biogeography. It also introduces the concept of neoteny, an evolutionary trick that enabled dinosaurs to become birds and humans to conquer the planet. The Vegavis's Story explores the evidence for a Cretaceous origin of modern birds and why they were able to survive the asteroid collision that saw the demise not only of dinosaurs but of up to three-quarters of all species. The Duck's Story switches to sex: why have so few species retained the ancestral copulatory organ? Or, put another way, why do most birds exhibit the paradoxical phenomenon of penis loss, despite all species requiring internal fertilisation? The Hoatzin's Story reveals unexpected oceanic rafting from Africa to South America: a stranger-than-fiction means of dispersal that is now thought to account for the presence of other South American vertebrates, including geckos and monkeys. The latest theories underpinning speciation are also explored. The Manakin’s Story, for example, reveals how South America’s extraordinarily rich avifauna has been shaped by past geological, oceanographic and climatic changes, while The Storm-Petrel’s Story examines how species can evolve from an ancestral population despite inhabiting the same geographical area. The thorny issue of what constitutes a species is discussed in The Albatross's Story, while The Penguin’s Story explores the effects of environment on phenotype ― in the case of the Emperor penguin, the harshest on the planet. Recent genomic advances have given scientists novel approaches to explore the distant past and have revealed many unexpected journeys, including the unique overland dispersal of an early suboscine from Asia to South America (The Sapayoa’s Story) and the blackbird's ancestral sweepstake dispersals across the Atlantic (The Thrush’s Story). Additional vignettes update more familiar concepts that encourage speciation: sexual selection (The Bird-of-Paradise's Story); extended phenotypes (The Bowerbird's Story); hybridisation (The Sparrow's Story); and 'great speciators' (The White-eye's Story). Finally, the book explores the raft of recent publications that help explain the evolution of cognitive skills (The Crow's Story); plumage colouration (The Starling's Story); and birdsong (The Finch's Story)

Book excerpt: The New York Times–bestselling author of H is for Hawk explores the human relationship to the natural world in this “dazzling” essay collection (Wall Street Journal). In Vesper Flights, Helen Macdonald brings together a collection of her best loved essays, along with new pieces on topics ranging from nostalgia for a vanishing countryside to the tribulations of farming ostriches to her own private vespers while trying to fall asleep. Meditating on notions of captivity and freedom, immigration and flight, Helen invites us into her most intimate experiences: observing the massive migration of songbirds from the top of the Empire State Building, watching tens of thousands of cranes in Hungary, seeking the last golden orioles in Suffolk’s poplar forests. She writes with heart-tugging clarity about wild boar, swifts, mushroom hunting, migraines, the strangeness of birds’ nests, and the unexpected guidance and comfort we find when watching wildlife.
Download or read book How Birds Evolve written by Douglas J. Futuyma and published by Princeton University Press. This book was released on 2021-10-19 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: A marvelous journey into the world of bird evolution How Birds Evolve explores how evolution has shaped the distinctive characteristics and behaviors we observe in birds today. Douglas Futuyma describes how evolutionary science illuminates the wonders of birds, ranging over topics such as the meaning and origin of species, the evolutionary history of bird diversity, and the evolution of avian reproductive behaviors, plumage ornaments, and social behaviors. In this multifaceted book, Futuyma examines how birds evolved from nonavian dinosaurs and reveals what we can learn from the "family tree" of birds. He looks at the ways natural selection enables different forms of the same species to persist, and discusses how adaptation by natural selection accounts for the diverse life histories of birds and the rich variety of avian parenting styles, mating displays, and cooperative behaviors. He explains why some parts of the planet have so many more species than others, and asks what an evolutionary perspective brings to urgent questions about bird extinction and habitat destruction. Along the way, Futuyma provides an insider's perspective on how biologists practice evolutionary science, from studying the fossil record to comparing DNA sequences among and within species. A must-read for bird enthusiasts and curious naturalists, How Birds Evolve shows how evolutionary biology helps us better understand birds and their natural history, and how the study of birds has informed all aspects of evolutionary science since the time of Darwin.

Download or read book Where Song Began written by Tim Low and published by Yale University Press. This book was released on 2016-09-27 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: An authoritative and entertaining exploration of Australia’s distinctive birds and their unheralded role in global evolution Renowned for its gallery of unusual mammals, Australia is also a land of extraordinary birds. But unlike the mammals, the birds of Australia flew beyond the continent’s boundaries and around the globe many millions of years ago. This eye-opening book tells the dynamic but little-known story of how Australia provided the world with songbirds and parrots, among other bird groups, why Australian birds wield surprising ecological power, how Australia became a major evolutionary center, and why scientific biases have hindered recognition of these discoveries. From violent, swooping magpies to tool-making cockatoos, Australia’s birds are strikingly different from birds of other lands—often more intelligent and aggressive, often larger and longer-lived. Tim Low, a renowned biologist with a rare storytelling gift, here presents the amazing evolutionary history of Australia’s birds. The story of the birds, it turns out, is inseparable from the story of the continent itself and also the people who inhabit it.
Download or read book The Ascent of Information written by Caleb Scharf and published by Penguin. This book was released on 2022-06-14 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Full of fascinating insights drawn from an impressive range of disciplines, The Ascent of Information casts the familiar and the foreign in a dramatic new light.” —Brian Greene, author of The Elegant Universe Your information has a life of its own, and it’s using you to get what it wants. One of the most peculiar and possibly unique features of humans is the vast amount of information we carry outside our biological selves. But in our rush to build the infrastructure for the 20 quintillion bits we create every day, we’ve failed to ask exactly why we’re expending ever-increasing amounts of energy, resources, and human effort to maintain all this data. Drawing on deep ideas and frontier thinking in evolutionary biology, computer science, information theory, and astrobiology, Caleb Scharf argues that information is, in a very real sense, alive. All the data we create—all of our emails, tweets, selfies, A.I.-generated text and funny cat videos—amounts to an aggregate lifeform. It has goals and needs. It can control our behavior and influence our well-being. And it’s an organism that has evolved right alongside us. This symbiotic relationship with information offers a startling new lens for looking at the world. Data isn’t just something we produce; it’s the reason we exist. This powerful idea has the potential to upend the way we think about our technology, our role as humans, and the fundamental nature of life. The Ascent of Information offers a humbling vision of a universe built of and for information. Scharf explores how our relationship with data will affect our ongoing evolution as a species. Understanding this relationship will be crucial to preventing our data from becoming more of a burden than an asset, and to preserving the possibility of a human future.

Download or read book Phoenix and the Birds of Prey written by Mark Moyar and published by U of Nebraska Press. This book was released on 2007-12-01 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study explodes prevailing myths about the Phoenix Program, the CIA's top-secret effort to destroy the Viet Cong by neutralizing its “civilian” leaders. Drawing on recently declassified documents and interviews with American, South Vietnamese, and North Vietnamese sources, Mark Moyar examines the attempts to eradicate the Viet Cong infrastructure and analyzes their effectiveness. He addresses misconceptions about these efforts and provides an accurate, complete picture of the allies’ decapitation of the Viet Cong shadow government. Combining social and political history with a study of military operations, Moyar offers a fresh interpretation of the crucial role the shadow government played in the Viet Cong's ascent. Detailed accounts of intelligence operations provide an insider’s view of their development and reveal what really happened in the safe havens of the Viet Cong. Filled with new information, Moyar’s study sets the record straight about one of the last secrets of the Vietnam War and offers poignant lessons for dealing with future Third World insurgencies. This Bison Books edition includes a new preface and chapter by the author.
Download or read book Falconer on the Edge written by Rachel Dickinson and published by Houghton Mifflin Harcourt. This book was released on 2009 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rachel Dickinson profiles falconer Steve Chindgren, a man willing to make extreme sacrifices to continue practicing the sport that has ruled his life. Dickinson arrives at a sense of falconry’s allure: the unpredictable nature of the hunt and the soaring exhilaration of success. Further exploration unveils the enormous emotional cost to a falconer who establishes an extraordinary tie to his birds. When, in the space of two days, Chindgren loses two birds that he’d been training for years, he is plunged into a profound depression that is only deepened when Jomo, his best bird, slows down because of old age. In addition to this challenge, Chindgren faces the danger to falconry that the modern world presents. Grouse habitat is being degraded by mining, agriculture, and gas industry interests. And the number of falconers is dwindling--the corps is graying and has few acolytes. Falconry is a sport that requires persistence, stoicism, and sacrifice; in this captivating account, Dickinson illuminates a fascinating subculture and one of its most hard core personalities.
Download or read book Peterson Field Guide To Bird Sounds Of Eastern North America written by Nathan Pieplow and published by HarperCollins. This book was released on 2017-03-07 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first comprehensive guide to the sounds of eastern North American birds, featuring an innovative visual index that allows readers to quickly look up unfamiliar sounds in the field. Bird songs and calls are just as important as visual field marks in identifying birds. But until now, the only way to learn them was by memorization. With this groundbreaking book, it’s possible to visually distinguish bird sounds and identify birds using a field guide format. At the core of this guide is the spectrogram, a visual graph of sound. With a brief introduction to five key aspects—speed, repetition, pauses, pitch pattern, and tone quality—readers can learn to visualize sounds, without any musical training or auditory memorization. Picturing sounds makes it possible to search this book visually for a bird song heard in the field. The Sound Index groups similar songs together, narrowing the identification choices quickly to a brief list of birds that sound alike. Readers can then turn to the species account for more information and/or listen to the accompanying audio tracks available online, through Cornell's Lab of Ornithology. Identifying birds by sound is arguably the most challenging and important skill in birding. This book makes it vastly easier to master than ever before.

Download or read book The Ascent to Truth written by Thomas Merton and published by HMH. This book was released on 2002-11-04 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author of The Seven Storey Mountain explores the mysticism of Saint John of the Cross. The only thing that can save the world from complete moral collapse is a spiritual revolution. . . . The desire for unworldliness, detachment, and union with God is the most fundamental expression of this revolutionary spirit. In Ascent to Truth, author and Trappist Monk Thomas Merton makes an impassioned case for the importance of contemplation. Drawing on a range of thinkers—from Carl Jung to Pope Pius XII—Merton defines the nature of contemplative experience and shows how the Christian mysticism of sixteenth-century Spanish Carmelite Saint John of the Cross offers essential answers to our disquieting and troubling times. “For any who have the desire to look into meditation and contemplation . . . this is the book for which they have waited.” —New York Herald Tribune Book Review “For those who may be curious about mysticism, and for those who may be called to a life of contemplation, this is an excellent book.” —Catholic World
Download or read book The World Only Spins Forward written by Isaac Butler and published by Bloomsbury Publishing USA. This book was released on 2018-02-13 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Marvelous . . . A vital book about how to make political art that offers lasting solace in times of great trouble, and wisdom to audiences in the years that follow."- Washington Post NAMED ONE OF THE BEST BOOKS OF THE YEAR BY NPR A STONEWALL BOOK AWARDS HONOR BOOK The oral history of Angels in America, as told by the artists who created it and the audiences forever changed by it--a moving account of the AIDS era, essential queer history, and an exuberant backstage tale. When Tony Kushner's Angels in America hit Broadway in 1993, it won the Pulitzer Prize, swept the Tonys, launched a score of major careers, and changed the way gay lives were represented in popular culture. Mike Nichols's 2003 HBO adaptation starring Meryl Streep, Al Pacino, and Mary-Louise Parker was itself a tour de force, winning Golden Globes and eleven Emmys, and introducing the play to an even wider public. This generation-defining classic continues to shock, move, and inspire viewers worldwide. Now, on the 25th anniversary of that Broadway premiere, Isaac Butler and Dan Kois offer the definitive account of Angels in America in the most fitting way possible: through oral history, the vibrant conversation and debate of actors (including Streep, Parker, Nathan Lane, and Jeffrey Wright), directors, producers, crew, and Kushner himself. Their intimate storytelling reveals the on- and offstage turmoil of the play's birth--a hard-won miracle beset by artistic roadblocks, technical disasters, and disputes both legal and creative. And historians and critics help to situate the play in the arc of American culture, from the staunch activism of the AIDS crisis through civil rights triumphs to our current era, whose politics are a dark echo of the Reagan '80s. Expanded from a popular Slate cover story and built from nearly 250 interviews, The World Only Spins Forward is both a rollicking theater saga and an uplifting testament to one of the great works of American art of the past century, from its gritty San Francisco premiere to its starry, much-anticipated Broadway revival in 2018.
Download or read book Remarkable Birds written by Mark Avery and published by Thames & Hudson. This book was released on 2016-09-13 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Everything you didn’t know about the avian world: a fascinating compendium showcasing the extraordinary wonders of birds, illuminated with exquisite ornithological illustrations, prints, and drawings Humans share the Earth with more than 10,000 species of birds and have always been enchanted by them. Birds can be a sign of the changing seasons, a symbol of freedom, or simply a breathtaking vision of beauty. Remarkable Birds approaches these fascinating creatures thematically across eight sections covering all aspects of humans’ relationship with birds. “Songbirds” celebrates the greatest bird virtuosi, such as the nightingale, while “Birds of Prey” includes majestic hunters such as the harpy eagle. “Feathered Travelers” describes astounding journeys made by birds including tiny hummingbirds that migrate huge distances. “The Love Life of Birds” illuminates the most brilliant displays upon which different species rely to find a mate—notably the extravagant plumage and dances of birds of paradise. “Avian Cities” explores the spectacular, large colonies of species such as the flamingo, while “Useful to Us” examines the diverse ways we find birds valuable, such as the turkey or the canary. “Threatened & Extinct” describes some species that have been lost forever, and others on the brink. Birds have also had great mystical significance and “Revered & Adored” considers such species as the sacred ibis, believed by the ancient Egyptians to represent the god Thoth.

Download or read book Unnatural Selection written by Katrina van Grouw and published by Princeton University Press. This book was released on 2018-07-31 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: A lavishly illustrated look at how evolution plays out in selective breeding Unnatural Selection is a stunningly illustrated book about selective breeding--the ongoing transformation of animals at the hand of man. More important, it's a book about selective breeding on a far, far grander scale—a scale that encompasses all life on Earth. We'd call it evolution. A unique fusion of art, science, and history, this book celebrates the 150th anniversary of Charles Darwin's monumental work The Variation of Animals and Plants under Domestication, and is intended as a tribute to what Darwin might have achieved had he possessed that elusive missing piece to the evolutionary puzzle—the knowledge of how individual traits are passed from one generation to the next. With the benefit of a century and a half of hindsight, Katrina van Grouw explains evolution by building on the analogy that Darwin himself used—comparing the selective breeding process with natural selection in the wild, and, like Darwin, featuring a multitude of fascinating examples. This is more than just a book about pets and livestock, however. The revelation of Unnatural Selection is that identical traits can occur in all animals, wild and domesticated, and both are governed by the same evolutionary principles. As van Grouw shows, animals are plastic things, constantly changing. In wild animals the changes are usually too slow to see—species appear to stay the same. When it comes to domesticated animals, however, change happens fast, making them the perfect model of evolution in action. Suitable for the lay reader and student, as well as the more seasoned biologist, and featuring more than four hundred breathtaking illustrations of living animals, skeletons, and historical specimens, Unnatural Selection will be enjoyed by anyone with an interest in natural history and the history of evolutionary thinking.
