Bird flight has always intrigued mankind. This book provides an up to date account of our existing knowledge on the subject, as well as offering new insights and challenging some established views. A brief history of the science of flight introduces the basic physical principles governing aerial locomotion. A treatment of flight-related functional morphology concentrates on the difference in shape of the arm and hand part of the wings, on the structure and function of tails, and on the shape of the body. The anatomy and mechanical properties of feathers receive special attention. Aerodynamic principles used by birds are explained in theory by simply applying Newton's laws, and in practice by showing the direction and velocity of the attached flow around an arm wing cross section and of the leading edge vortex flow above a hand wing. The Archaeopteryx fossils remain crucial in our understanding of the evolution of bird flight despite the recent discovery of a range of well-preserved ancient birds. A novel insight into the interactions between wings and air challenges established theories relating to the origin of bird flight. Take-off, flapping flight, gliding and landing are the basic ingredients of bird flight, and birds use a variety of flight styles from hovering to soaring. Flight muscles consisting of mosaics of specialised fibres are the engines that generate the force required to keep the wings and tail in the gliding configuration and perform work during flapping motion. The energy required to fly can be estimated or measured directly, and a comparison of the empirical results provides insights into the trend in metabolic costs of flight of birds varying in shape and mass from hummingbirds to albatrosses.

Bird migration is a charismatic topic that has fascinated naturalists for centuries. This book, the only concise and accessible synthesis of the area, describes not only the migrations, the incredible stamina and navigational skills of the birds, the effects on their distributions, survival, and evolution, but also the scientific skills and studies that underlie the information that has been gleaned about migration.

Avian Flight covers all the main aspects of aerial locomotion by birds including sections on the history of thinking about bird flight, aerodynamics, functional morphology, evolution, kinematics, physiology, energetics and the cost of flight. The subject is complex and still not yet fully understood, and the author argues a convincing case for rethinking or even abandoning some of the old, well-established concepts.

Birds are hosts to many parasites, internal and external. The parasites inevitably form a burden to the host bird and therefore may affect its ability to grow, survive, and reproduce; its behaviour; and the distribution and abundance of the whole species. In consequence, bird-parasite systems have attracted attention from diverse fields and the literature has been spread out in a wide range of specialized journals. The editors of this book have drawn together a comprehensive range of experts in the field to provide an invaluable reference of current work in bird-parasite interactions. The book is divided into four parts. The introduction provides the contemporary context of research in bird-parasite systems and presents case studies which combine theoretical concepts with experimental data. Subsequent parts focus on the ecology; behavioural responses; and the effect of parasitism on sexual selection.

Ask anybody what superpower they wished to possess and odds are the answer just might be "the ability to fly." What is it about soaring through the air held up by the power of one's own body that has captivated humans for so long? David Alexander examines the evolution of flight in the only four animals to have evolved this ability: insects, pterosaurs, birds, and bats. With an accessible writing style grounded in rigorous research, Alexander breaks new ground in a field that has previously been confined to specialists. While birds have received the majority of attention from flight researchers, Alexander pays equal attention to all four groups of flyers-something that no other book on the subject has done before now. In a streamlined and captivating way, David Alexander demonstrates the links between the tiny 2-mm thrip and the enormous albatross with the 12 feet wingspan used to cross oceans. The book delves into the fossil record of flyers enough to satisfy the budding paleontologist, while also pleasing ornithologists and entomologists alike with its treatment of animal behavior, flapping mechanisms, and wing-origin theory. Alexander uses relatable examples to draw in readers even without a natural interest in birds, bees, and bats. He takes something that is so off-limits and unfamiliar to humans-the act of flying-and puts it in the context of experiences that many readers can relate to. Alexander guides readers through the anomalies of the flying world: hovering hummingbirds, unexpected gliders (squirrels, for instance), and the flyers that went extinct (pterosaurs). Alexander also delves into wing-origin theory and explores whether birds entered the skies from the trees down (as gliders) or from the ground up (as runners) and uses the latest fossil evidence to present readers with an answer.

This book reports and summarizes the findings of several dozen studies that have used ptilochronology (the study of feather time) as a research tool. It provides a practical resource as well as a source of understanding of how the technique can be used to address important questions in avian biology.

The aim of this book is to give a general overview of the whole subject of bird migration. After a chapter describing the Earth's climate and ecosystem, the book is divided into three main sections. The first presents the life histories and migratory habits of nine different ecological categories of birds. The second section deals with the course and timing of the flight journeys, flight behavior, fuel economy, flocking, and the hazards from disorientation and predation. The final section covers the ways that birds navigate and shows that this process is still by no means fully understood.
