The Gannet


Book Description

This work is a distillation of the studies and researches on Sula bassana in Europe and North America, with frequent reference to the African and Australasian gannets. The author is internationally known for his work on the North Atlantic gannet and the boobies. His studies of the gannetry on the Bass Rock over many years have formed the basis for most of our knowledge of the gannet's ecology, its breeding cycle and behaviour. There is also a chapter on the boobies, all of which have been studied at first hand by the author. Chapter topics are plumage, shape, structure and voice; numbers and distribution; behaviour; ecology; the bird at sea; the gannet family and the order; the gannet and man. There are many tables, maps and a full bibliography. The authoritative text is complemented by John Busby's brilliant and evocative drawings, plus 32 pages of photographs, many unpublished hitherto.

Pelicans, Cormorants, and their Relatives


Book Description

The pelecaniformes are a large and important group of seabirds, containing many spectacular species. This book addresses the breeding biology of the six pelecaniform families, which comprise the closely-related core groups (pelicans, cormorants/shags, darters, gannets/boobies) and their more distant relatives, the frigate birds and tropic birds. Many fundamental questions can be addressed through the pelecaniformes: Why do they breed in colonies? What are the links between their feeding methods and their reproduction? What part does territorial and pairing behaviour play in their life-cycles? These and scores of comparable issues, including those related to man, are woven here into a richly interpretative text. The author's approach to the subject is threefold. First, the pelecaniformes are placed within the framework of four discrete disciplines, with chapters on evolutionary relationships, comparative behaviour, ecology, and the birds' relationship with humans. Secondly, each of the six families is discussed, elucidating the range of taxonomy, behaviour, and ecology within each. Finally, we progress to specific level, using the same structure as for the family accounts. In this way, each of the 60-odd species can be understood not just as discrete units, but as part of their family and order. The book is unique in its coverage of the entire order and in its combination of facts and interpretation. Pelicans, Cormorants, and their Allies will enable readers not only to identify the many spectacular species which make up this large and important group of seabirds, but also to understand their breeding biology.




Avian Biology


Book Description

Avian Biology,Volume VIII assesses selected aspects of avian biology. It is generally the conceptual descendant of Marshall's earlier treatise,"Biology and Comparative Physiology of Birds, but is more than simply a revision of it. This volume consists of two relatively lengthy, diverse chapters that focus on adaptive significance of coloniality in birds and fossil records of birds. In particular, this volume looks into group phenomena related to central place systems, that is, systems in which one or more individuals move to and from a centrally located place in the course of daily activities. It also addresses selective factors that have been suggested to explain why individuals should form colonies rather than disperse within the available foraging space. This book will be useful as a reference material for advanced students and instructors in this field of interest.




National Audubon Society Birds of North America


Book Description

Updated for the first time in decades, this unparalleled reference work is the most comprehensive and authoritative guide to the birds of North America and now includes the latest information on conservation status and the effects of climate change--from the world's most trusted name in birding, beloved by millions of backyard enthusiasts and experts alike “If you’ve ever wondered what birds show up in your backyard or which species you see when your family is on vacation, then this beautiful, freshly updated bird guide from the National Audubon Society is perfect for you.” —Portland Book Review Developed by the creators of the best-selling Audubon field guides, this handsome volume is the result of a collaboration among leading scientists, scholars, taxonomic and field experts, photo editors, and designers. An indispensable reference, it covers more than 800 species, with over 3,500 full-color photographs of birds in their natural habitat, often with four or five images of each species. For ease of use, the book includes a glossary, an index, and a ribbon marker, and is arranged according to the American Ornithological Society's latest Checklist of North and Middle American Birds—with birds sorted by taxonomic orders and grouped by family, so that related species are presented together. Range maps, reflecting the impact of climate change, accompany nearly every entry, along with a physical description and information on voice, nesting, habitat, and similar species. This guide also includes an important new category on conservation status and essays by leading scholars in each field who provide holistic insights into the world of birds. Whether trying to determine which owl is interrupting your dinner or successfully identifying all of the warblers that arrive in spring, readers will come to rely on this work of remarkable breadth, depth, and elegance. It is a must-have reference for the library of any birder, and is poised to become the number one guide in the field.




Seabird Energetics


Book Description

"Seabird Energetics" is a composite volume with a coherent theme. It makes a valuable contribution to our understanding of the costs of breeding, the significance of which goes far beyond physiology as a brief historical perspective may illustrate. After decades of mainly anecdotal observations by natu ralists with an interest in seabirds, there was still so little information that in 1954, David Lack in his book "The Natural Regulatiori of Animal Numbers" was forced to ignore seabirds in a way that would be unthinkable today. The late fifties, however, produced a seminal contribution to seabird ecology and behaviour in the series of papers which stemmed from the Centenary Expedi tion of the British Ornithologists' Union to Ascension Island. Not only had quantitative ecology become the norm but the interest aroused by the European Ethological approach to bird behaviour had led to properly descriptive and analytical studies of seabird behaviour. The complex interactions between social behaviour and ecology then received more attention and the sixties and seventies brought a flood of papers on ecology and on some social aspects of breeding ecology. V.C. Wynne-Edwards linked these two as part of his attempt to understand the mechanism of the regulation of animal populations in his book "Animal Dispersion in Relation to Social Behaviour" (1962). He paid considerable attention to seabirds and the phenomena of clutch and brood-size, deferred breeding, "rest" years, etc., although, unfortunately, the most relevant studies were yet to come.
