Book Description
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.

Book Description
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.

Book Description
This is the first re-appraisal in 50 years of concepts of development made in birds. This book is a case study in evolutionary diversification of life histories. Although birds have a rather uniform body plan and physiology, they exhibit marked variation in development type, parental care, and rate of growth. Altricial birds are fully dependent on their parents for warmth and nutrition and begin posthatching life in a more or less embryonic condition. At the other extreme, such superprecocial species as the megapodes are independent of all parental care from hatching, and the neonate, able to fly, resembles an adult bird. This book thus attempts to present an integrative perspective of organism biology, ecology, and evolution.

Book Description
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.

Book Description
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)
