Book excerpt: Birds are among the most successful vertebrates on Earth. An important part of our natural environment and deeply embedded in our culture, birds are studied by more professional ornithologists and enjoyed by more amateur enthusiasts than ever before. However, both amateurs and professionals typically focus on birds' behaviour and appearance and only superficially understand the characteristics that make birds so unique. The Inner Bird introduces readers to the avian skeleton, then moves beyond anatomy to discuss the relationships between birds and dinosaurs and other early ancestors. Gary Kaiser examines the challenges scientists face in understanding avian evolution - even recent advances in biomolecular genetics have failed to provide a clear evolutionary story. Using examples from recently discovered fossils of birds and near-birds, Kaiser describes an avian history based on the gradual abandonment of dinosaur-like characteristics, and the related acquisition of avian characteristics such as sophisticated flight techniques and the production of large eggs. Such developments have enabled modern birds to invade the oceans and to exploit habitats that excluded dinosaurs for millions of years. While ornithology is a complex discipline that draws on many fields, it is nevertheless burdened with obsolete assumptions and archaic terminology. The Inner Bird offers modern interpretations for some of those ideas and links them to more current research. It should help anyone interested in birds to bridge the gap between long-dead fossils and the challenges faced by living species.

Download or read book Avian Evolution written by Gerald Mayr and published by John Wiley & Sons. This book was released on 2016-09-08 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Texas Waterfowl written by William P. Johnson and published by Texas A&M University Press. This book was released on 2013-01-18 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this beautifully illustrated guide, two practicing wildlife biologists describe the life histories of forty-five species of ducks, geese, and swans that occur in Texas. For common species and those that breed in the state, each account begins with an interesting fact (such as, “Red-breasted Mergansers have been clocked at over 80 mph, the fastest recorded flight speed for a duck . . .”) and provides information on Texas distribution and harvest, population status, diet, range and habitats, reproduction, and appearance. Exquisite photographs, informative distribution maps, and a helpful source list accompany the species descriptions, and the book offers a glossary and full bibliography for those who want to explore the literature further. With the degradation and disappearance of the inland and coastal habitats that these birds depend upon, the natural history of these waterfowl species provides a vital reminder of the interconnectedness and crucial importance of all wetlands. Birders, biologists, landowners, hunters, outdoor enthusiasts, and all those interested in the health and preservation of our coastal and inland wetland resources will enjoy and learn from this book.

Download or read book A Hundred Years of Texas Waterfowl Hunting written by R. K. Sawyer and published by Texas A&M University Press. This book was released on 2012-07-13 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: The days are gone when seemingly limitless numbers of canvasbacks, mallards, and Canada geese filled the skies above the Texas coast. Gone too are the days when, in a single morning, hunters often harvested ducks, shorebirds, and other waterfowl by the hundreds. The hundred-year period from the mid-nineteenth to the mid-twentieth centuries brought momentous changes in attitudes and game laws: changes initially prompted by sportsmen who witnessed the disappearance of both the birds and their spectacular habitat. These changes forever affected the state’s storied hunting culture. Yet, as R. K. Sawyer discovered, the rich lore and reminiscences of the era’s hunters and guides who plied the marshy haunts from Beaumont to Brownsville, though fading, remain a colorful and essential part of the Texas outdoor heritage. Gleaned from interviews with sportsmen and guides of decades past as well as meticulous research in news archives, Sawyer’s vivid documentation of Texas’ deep-rooted waterfowl hunting tradition is accompanied by a superb collection of historical and modern photographs. He showcases the hunting clubs, the decoys, the duck and goose calls, the equipment, and the unique hunting practices of the period. By preserving this account of a way of life and a coastal environment that have both mostly vanished, A Hundred Years of Texas Waterfowl Hunting also pays tribute to the efforts of all those who fought to ensure that Texas’ waterfowl legacy would endure. This book will aid their efforts, along with those of coastal residents, birders, wildlife biologists, conservationists, and all who are interested in the state’s natural history and in championing the preservation of waterfowl and wetland resources for the benefit of future generations.
Download or read book The Life of David Lack written by Ted R. Anderson and published by Oxford University Press. This book was released on 2013-06-01 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most people who have taken a biology course in the past 50 years are familiar with the work of David Lack, but few remember his name. Almost all general biology texts produced during that period have a figure showing the beak size differences among the finches of the Galapagos Islands from Lack's 1947 classic, Darwin's Finches. Lack's pioneering conclusions in Darwin's Finches mark the beginning of a new scientific discipline, evolutionary ecology. Tim Birkhead, in his acclaimed book, The Wisdom of Birds, calls Lack the 'hero of modern ornithology.' Who was this influential, yet relatively unknown man? The Life of David Lack, Father of Evolutionary Ecology provides an answer to that question based on Ted Anderson's personal interviews with colleagues, family members and former students as well as material in the extensive Lack Archive at Oxford University.
