2009 sees the celebration of 100 years of bird ringing in Britain and Ireland, and this guide highlights some of the major achievements of the Scheme over that time.
This guide is an ideal training tool for ringers, explaining how and why we ring birds. It contains numerous examples of how ringing has contributed to conservation science and research, and how it helps us understand population changes by providing information on survival and recruitment. The guide is also a great introduction to bird ringing for non-ringers, not only highlighting the Scheme’s successes, but also explaining why we still need to keep ringing today.

This book offers the first summary of Ptilochronology, the study of the growth of bird feathers as an indicator of health and nutritional condition. Offers insights into the methods, conceptual issues and related research and is a most useful resource for ornithologists.
Reports and summarizes the findings of several studies that have used ptilochronology as a research tool. This work 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. It is useful for professional avian biologists and ornithologists. This is the first book to summarize the methods, conceptual issues and results of studies using the interpretation of feather growth rates as an index of nutritional condition in birds. The author has coined the term ptilochronology (literally, ‘the study of feather time’) to describe this technique, which relies on the fact that as a feather grows it produces visible growth bars. Both the technique and its conceptual foundations have been applied worldwide to numerous studies of avian evolution, ecology, and conservation biology. The author reviews this work, chronicles the various criticisms that have been made, and describes how these have influenced the development of ptilochronology. He goes on to suggest experimental methodologies and analytical techniques to safeguard against invalid results. A final chapter summarises this new technique’s contribution to avian biology, and suggests potential applications and a future research agenda. An appendix details specific measurements and describes the methodology associated with ptilochronology., “Ptilochronology” provides a practical resource as well as a conceptual understanding of how this technique can be used to address important questions in avian biology. It will be of relevance and use to professional avian biologists and ornithologists as well as to graduate students of avian behavioural ecology, evolution and conservation.
In this book, physicist Mark Denny explains, in a clear, accessible style, the science of bird migration, from the intricacies of bird aeronautics to the newly unraveled mysteries of their magnetic compasses. While providing wherever possible examples of indigenous Hawaiian species, the book surveys the migration phenomenon as a whole, showing that birds are breathtaking works of engineering with spectacular capabilities for long-distance flights. Each year thousands of these hardy migrants fly 2,500 miles nonstop from Alaska to Hawaii. How do they endure such marathon journeys, and how on earth do they know which direction to travel over featureless ocean? In fact, many migratory journeys, in all parts of the world are performed by birds as small as warblers and as large as swans, cover much longer distances.
Denny explores how researchers study bird migration; how they gather data from old-fashioned bird banding, high-tech satellite tracking, and other techniques; and above all how the birds do it. Throughout the book, concepts such as the physics of bird flight and the role of physical geography on navigation are explained in a relatively math-free way. Denny also examines past adaptations migrating birds have made to changing environments and the challenges they face in the future, as the world beneath them faces rapid climate change exacerbated by human activity.
This book – a visual guide to the structure and anatomy of birds – is one of the most heavily illustrated ornithology references ever written. A concise atlas of avian anatomy, it contains more than 200 specifically prepared, accurate, and clear drawings. The text is as informative as the drawings; written at a level appropriate to undergraduate students and to bird watchers in general, it explains why birds look and act the way they do.
This book features the work of seven photographers who have spent their lives camping out, donning waders, and lying in wait for the greatest shots of birds doing what they do best: flying! Selected by birder and photographer Richard Ettlinger, these gorgeous, often thrilling images show hunters, migrators, waterfowl, and songbirds living on the wing: hunting, feeding, fighting, travelling, or just gliding along. An essay by Ettlinger gives an overview of the mechanics and evolution of bird flight.
