Download or read book The Gannet written by Bryan Nelson and published by A&C Black. This book was released on 2010-11-30 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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authoritative text is complemented by John Busby's brilliant and evocative drawings, plus 32 pages of photographs, many unpublished hitherto.

Book excerpt: 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.

Download or read book Pelicans Cormorants and their Relatives written by J. Bryan Nelson and published by OUP Oxford. This book was released on 2006-01-26 with total page 680 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Paleogene Fossil Birds written by Gerald Mayr and published by Springer Nature. This book was released on 2022-02-12 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second, completely revised edition of “Paleogene fossil birds” gives a comprehensive, updated overview of the avian fossil record from a geological period that lasted from the end-Cretaceous mass extinction event (66 million years ago) to the end of the Oligocene epoch (23 mya). Paleogene avifaunas are highly diversified and not only feature unusual archaic groups without close living relatives but also offer unique insights into the evolution and biogeographic history of extant birds. The main body of the book constitutes an in-depth survey of the known diversity of Paleogene avifaunas. The reader is introduced into basic skeletal features of extinct avian taxa, with these fossil forms being placed into a phylogenetic context in the light of current hypotheses on the interrelationships of extant birds. The geographical and temporal occurrences of the various fossil groups are outlined and their evolutionary significance is discussed. Concluding sections inform more general aspects of Paleogene avifaunas, such as possible causes of major faunal changes. In addition to being a reference work for the early evolution of modern birds from a paleornithological perspective, the present work also enables researchers in other fields of vertebrate paleontology to gain an improved understanding of Paleogene ecosystems. Numerous color photos of representative specimens furthermore make the new edition attractive to a wider audience interested in the avian fossil record.

Available in PDF, EPUB and Kindle. Book excerpt: "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.

Download or read book Lost Land of the Dodo written by Anthony Cheke and published by A&C Black. This book was released on 2009-01-01 with total page 824 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mascarene islands in the southern Indian Ocean - Mauritius, Réunion and Rodrigues - were once home to an extraordinary range of birds and reptiles. Evolving on these isolated volcanic islands in the absence of mammalian predators or competitors, the land was dominated by giant tortoises, parrots, skinks and geckos, burrowing boas, flightless rails & herons, and of course (in Mauritius) the Dodo. Uninhabited and only discovered in the 1500s, colonisation by European settlers in the 1600s led to dramatic changes in the ecology of the islands; the birds and tortoises were slaughtered indiscriminately while introduced rats, cats, pigs and monkeys destroyed their eggs, the once-extensive forests logged, and invasive introduced plants from all over the tropics devastated the ecosystem. The now-familiar icon of extinction, the Dodo, was gone from Mauritius within 50 years of human settlement, and over the next 150 years many of the Mascarenes' other native vertebrates followed suit. The product of over 30 years research by Anthony Cheke, Lost Land of the Dodo provides a comprehensive yet hugely enjoyable account of the story of the islands' changing ecology, interspersed with human stories, the islands' biogeographical anomalies, and much else. Many French publications, old and new, especially for Réunion, are discussed and referenced in English for the first time. The book is richly illustrated with maps and contemporary illustrations of the animals and their environment, many of which have rarely been reprinted before. Illustrated box texts look in detail at each extinct vertebrate species, while Julian Hume's superb colour plates bring many of the extinct birds to life. Lost Land of the Dodo provides the definitive account of this tragic yet remarkable fauna, and is a must-read for anyone interested in islands, their ecology and the history of our relationship with the world around us.

Download or read book Avian Evolution written by Gerald Mayr and published by John Wiley & Sons. This book was released on 2016-10-31 with total page 341 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 Blue Footed Boobies written by Hugh Drummond and published by Oxford University Press. This book was released on 2023 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Aggressive competition between sibling chicks differs between blue-footed and brown boobies. In a brood of two blue-foot chicks, the senior one (four days older) maintains dominance over the three-month nestling period by daily low-level attacking, ensuring privileged growth and survival for itself by limiting junior's begging and feeding. Both blue-foot siblings often survive and fledge, but when parents provide insufficient food, senior increases its aggression and junior starves to death or gets killed by adult neighbors while seeking adoption in their nests. In contrast, brown booby parents bring less food to their broods and their senior chicks are unconditionally intolerant and violent; they attack their sibling at every opportunity and toss it out of the nest, to certain death. The behavioral roles of booby family members - including conditional sharing, siblicide, and parental passivity - are explained by Hamilton's theory of inclusive fitness and kin selection, which also applies to humans"--
