Download or read book Romancing the Birds and Dinosaurs written by Alan Feduccia and published by BrownWalker Press. This book was released on 2020-10-15 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Birds and dinosaurs have dominated human interest for decades. In this well-supported revolutionary view of the field, critical questions are explored with credible evidence and biological thought. Are birds derived directly from advanced dinosaurs, or are they closely related dinosaur cousins? Did flight originate via the natural "gravity-assisted" trees-down model, or from the improbable “gravity-resisted” ground-up model? Were the earliest birds ground-predators or trunk-climbing gliders? Were dinosaurs hot-blooded with insulating protofeathers, or highly active, cold-blooded reptiles? These are among the questions addressed in this path-breaking book. Current consensus suggests that early birds were earth-bound and flight began on the ground. Reversing that logic, since birds are hot-blooded, by inference so too were dinosaurs, and extraordinarily complex feathers, flight brain and inner ear, evolved before flight in dinosaurs. The iconic early bird Archaeopteryx, despite innumerable flight and arboreal features, is now displayed as an earth-bound predator that could not fly. In reality, we have yet to provide satisfactory explanations for much of the biological origin and early evolution of birds. Among the questions addressed is whether truly feathered dinosaurs are in reality lost or "hidden birds?" The architectural complexity of feathers leads the author to the conclusion that if an animal has evolved extraordinarily complex, aerodynamically-designed feathers, an avian flight hand, flight membranes, and a flight brain, it's a bird. Birds and dinosaurs captivate and enchant the human imagination. These intriguing animals have dominated the field of paleontology and evolution for the past half century, engendering heated debate on avian ancestry, the origin of flight and feathers, and the biology of their fossils. Are birds living dinosaurs? In this series of entertainingly contentious and captivating essays evolutionary biologist Alan Feduccia writes with verve and humor to expose major problems in the field and advocate liberation from the shackles of consensus thinking about birds and dinosaurs. He maintains that the euphoria of paleontologists claiming to have solved the major problems of bird evolution is premature, largely generated by the adoption of a rigid, cult-like methodology, heavily blended with ideology, and excluding many biological and geological principles. He adroitly exposes and elucidates major mistakes in the field and their aftermath. Romancing the Birds and Dinosaurs is a lucid revelation of clarity and synthesis, a fascinating unveiling of the underlying science that has produced the good, but also often appalling fossil research and wild speculation in bird and dinosaur evolution. A must read for anyone interested in this rapidly evolving field, the short, concise and incisive essays provide the reader with access to this complex topic. REVIEWS and WORDS OF PRAISE In this strikingly unconventional and brilliant book, Professor Alan Feduccia presents the current status of the recent controversy about the origin of birds with clarity and vigor. A thought-provoking personal exploration of what the bird fossils represent. ---Sankar Chatterjee, Paul Whitfield Horn Distinguished Professor of Geosciences and Curator of Paleontology, Texas Tech University. Feduccia's book eloquently reminds us that consensus science is to be shied away from especially when it is used to plead special cases against basic scientific principles. The concept of “lost birds” is particularly intriguing as it defines what birds are and how special science obfuscates the simplicity of evolution. ---David A. Burnham, Associate Researcher, University of Kansas Biodiversity Institute and Natural History Museum. Based on a thorough understanding of the empirical evidence, Feduccia presents a convincing account of avian origins from their putative ancestors. ---Walter J. Bock, Professor of Evolutionary Biology, Columbia University and Research Associate, American Museum of Natural History. With candor, clear thinking, humor, and abundant evidence, Alan Feduccia’s Romancing the Birds and Dinosaurs should be mandatory reading for the countless millions who are intrigued by dinosaurs and their relatives, the birds. Feduccia points out the many empirical and logical shortcomings in the stubborn majority view that birds evolved from dinosaurs, an idea now solidly entrenched as dogma in education and popular culture. This new book will be as interesting to those who study human behavior and scientific methods as it will to students of vertebrate evolution. ---David W. Steadman, Curator of Ornithology, Professor of Biology, Florida Museum of Natural History, University of Florida.

Download or read book Rails written by Barry Taylor and published by A&C Black. This book was released on 2010-08-30 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a guide to rails, a relatively homogeneous family of birds spread throughout the world. Barry Taylor and Ber van Perlo have described and illustrated 145 species of rails, including two that are newly described, and also ten that are recently extinct and two that are almost certainly extinct. The book, based on up-to-date references and on new observations, is the first to give comprehensive information on field identification (including voice), covering all species and races for which details are known. It is also the first to provide descriptions of the immature and juvenile plumages of many species. The authors provide a detailed summary of current knowledge of all aspects of rail biology and their often complex behaviour, social structure, and family life. They explain how such apparently poorly flying birds can undertake intercontinental migrations and are such widespread and successful colonists of remote oceanic islands. They also discuss the remarkable ease and speed with which species on such islands have evolved into flightless forms in the absence of predators, a fact that has led to the rapid extinction of numerous island taxa following the arrival of man. Rail habitats are fast disappearing, say the authors, and many rails become endangered before enough is known about them to plan effective conservation measures. The book provides information on distribution, status, habitat requirements, and current threats, and it gives conservation priorities for threatened species.

Available in PDF, EPUB and Kindle. Book excerpt: "Inspired by the spectacular discoveries of the past two decades from the Age of Reptiles in China, Riddle of the Feathered Dragons explores how these miraculous fossils have transformed the contentious arena of bird and dinosaur evolution. Aside from being the most comprehensive discussion of these avian and associated discoveries, the author delves into the world of investigative journalism to expose the darker side of the world of fossil birds and dinosaurs. The book exposes the massive unfounded speculation that has characterized the field of vertebrate paleontology and published extensively in the world's most prestigious journals, including everything from supposed dinosaur protein to so-called feathered dinosaurs. The book questions the validity of the foundational tenets of the now "unquestionable orthodoxy" of bird and dinosaur evolution, including bird origins, feathered dinosaurs, flight origin from the ground-up and hot-blooded dinosaurs and their proteins. It exposes how speculation has gone far beyond the ability of the currently available evidence to yield answers. The author concludes that birds are best defined by a more traditional definition of the possession of feathers and avian flight architecture, that the so-called "feathered dinosaurs" are most likely derived avians, and that flight clearly originated from the trees-down, from ancestors that antedated the dinosaurs, rather than a direct linear descent"--

Download or read book Taking Wing written by Pat Shipman and published by Simon and Schuster. This book was released on 1999-01-15 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1861, just a few years after the publication of Charles Darwin's On the Origin of Species, a scientist named Hermann von Meyer made an amazing discovery. Hidden in the Bavarian region of Germany was a fossil skeleton so exquisitely preserved that its wings and feathers were as obvious as its reptilian jaws and tail. This transitional creature offered tangible proof of Darwin's theory of evolution. Hailed as the First Bird, Archaeopteryx has remained the subject of heated debates for the last 140 years. Are birds actually living dinosaurs? Where does the fossil record really lead? Did flight originate from the "ground up" or "trees down"? Pat Shipman traces the age-old human desire to soar above the earth and to understand what has come before us. Taking Wing is science as adventure story, told with all the drama by which scientific understanding unfolds.

Download or read book What It s Like to Be a Bird written by David Allen Sibley and published by Knopf. This book was released on 2020-04-14 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: The bird book for birders and nonbirders alike that will excite and inspire by providing a new and deeper understanding of what common, mostly backyard, birds are doing—and why: "Can birds smell?"; "Is this the same cardinal that was at my feeder last year?"; "Do robins 'hear' worms?" "The book's beauty mirrors the beauty of birds it describes so marvelously." —NPR In What It's Like to Be a Bird, David Sibley answers the most frequently asked questions about the birds we see most often. This special, large-format volume is geared as much to nonbirders as it is to the out-and-out obsessed, covering more than two hundred species and including more than 330 new illustrations by the author. While its focus is on familiar backyard birds—blue jays, nuthatches, chickadees—it also examines certain species that can be fairly easily observed, such as the seashore-dwelling Atlantic puffin. David Sibley's exacting artwork and wide-ranging expertise bring observed behaviors vividly to life. (For most species, the primary illustration is reproduced life-sized.) And while the text is aimed at adults—including fascinating new scientific research on the myriad ways birds have adapted to environmental changes—it is nontechnical, making it the perfect occasion for parents and grandparents to share their love of birds with young children, who will delight in the big, full-color illustrations of birds in action. Unlike any other book he has written, What It's Like to Be a Bird is poised to bring a whole new audience to David Sibley's world of birds.
