Jonathan Safran Foer has long had a passion for the work of the twentieth-century American assemblage artist Joseph Cornell. Inspired by Cornell�s avian-themed boxes, and suspecting that they would be similarly inspiring to others, Foer began to write letters. The responses he received from luminaries of American writing were nothing short of astounding. Twenty writers generously contributed pieces of prose and poetry that are as eclectic as they are imaginative, and the result is a unique collaborative project and one of the most significant engagements of literature with art for many years.
There is more to a bird than simply feathers. And just because birds evolved from a single flying ancestor doesn't mean they are structurally the same. With 385 stunning drawings depicting 200 species, The Unfeathered bird is a richly illustrated book on bird anatomy that offers refreshingly original insights into what goes on beneath the feathered surface.
Covers "approximately 400 species" and has "more than 100 maps."
"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"--
"The first comprehensive and in-depth assessment of Minnesota's breeding birds in nearly a century, The Breeding Birds of Minnesota offers an unprecedented, extraordinarily detailed, finely illustrated account of 250 of those birds, including their historical and present breeding distribution, habitat, population abundance, and prospects for the future"--
Knowledge of the evolutionary history of birds has much improved in recent decades. Fossils from critical time periods are being described at unprecedented rates and modern phylogenetic analyses have provided a framework for the interrelationships of the extant groups. This book gives an overview of the avian fossil record and its paleobiological significance, and it is the only up-to-date textbook that covers both Mesozoic and more modern-type Cenozoic birds in some detail. The reader is introduced to key features of basal avians and the morphological transformations that have occurred in the evolution towards modern birds. An account of the Cenozoic fossil record sheds light on the biogeographic history of the extant avian groups and discusses fossils in the context of current phylogenetic hypotheses. This review of the evolutionary history of birds not only addresses students and established researchers, but it may also be a useful source of information for anyone else with an interest in the evolution of birds and a moderate background in biology and geology.
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.
