Download or read book The North American Swans Their Biology and Conservation written by Paul Johnsgard and published by Lulu.com. This book was released on 2020-03-23 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among birds, swans are relatively long-lived species and are also among the most strongly monogamous, having prolonged pair and family bonds that strongly influence their reproductive and general social behavior, which, in combination with their beauty and elegance, contribute to the overall high degree of worldwide human interest in them. This volume of more than 59,000 words describes the distributions, ecology, social behavior, and breeding biologies of the four species of swans that breed or have historically bred in North America, including the native trumpeter and tundra swans, the introduced mute swan, and the marginally occurring whooper swan. Also included are 5 distribution maps, 15 drawings, 27 photographs by the author, and a reference section of nearly 1,000 literature citations.

Download or read book The Whooper Swan written by Mark Brazil and published by A&C Black. This book was released on 2010-01-31 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first ever monograph on the Whooper Swan. This species is found in the northern Palearctic and is the world's most widely distributed swan. It is a familiar bird in northern Europe and across Asia to the far East, and is particularly noticeable when migrating between breeding and wintering grounds in large, noisy flocks. This migratory behaviour makes it a powerful symbol of seasonal change, and this, together with the bird's beautiful appearance, make it a popular subject of folklore and legend. For much of its range the Whooper Swan is the archetypal 'wild swan', and its voice and appearance is deeply evocative of time and place. This book looks at all aspects of the life and times of this enchanting bird. The book includes chapters on taxonomy, population, range and distribution, diet, breeding biology, behaviour, migratory behaviour and longevity, as well as taking a look at the swan's associations with our own species in history and legend and throughout its geographic range. This book is a brilliantly readable and exhaustively researched monograph. It is illustrated throughout with numerous photographs and line drawings, illustrating various aspects of the species' behaviour and morphology. It will appeal greatly to all those with an interest in birdwatching, especially those who already know something of this wonderful and inspirational bird.
Download or read book Limnology and Aquatic Birds written by Alan R. Hanson and published by Springer Science & Business Media. This book was released on 2009-03-20 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long-term population monitoring is an important tool in our investigations of the role waterbirds play in their environment. This book is international in scope and presents information on species as diverse as the Common Loon, Harlequin Duck, and Semi-Palmated Sandpiper, and habitat in locations ranging from Iceland to Japan. Papers presented in this volume further our understanding of the important role that limnology plays in determining habitat suitability for waterbirds.
Download or read book Partnerships in Birds The Study of Monogamy written by Jeffrey M. Black and published by Oxford University Press, UK. This book was released on 1996-05-30 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some birds mate for life, while others have many partners. Why? In this book, fourteen classic studies of bird behaviour are brought together to compare the different partnership patterns from ecological and evolutionary perspectives. Often there is a battle of the sexes, as individual birds behave in the way that serves their best interests. Introductory and concluding chapters review the latest thinking on this fascinating subject. - ;Some birds mate for life, while others have many partners. In this book, fourteen studies are brought together to compare different partnership patterns from ecological and evolutionary perspectives. The subjects have been chosen to include the same species living in different habitats (Sparrowhawks) and at different population densities (Great Tits). There are comparisons between closely related species (Mute Swans and Bewick's Swans). The studies span the globe and the behavioural gradient, from Iceland's strictly monogamous Whooper Swans to Australia's sexually promiscuous Splendid Fairy-wrens. In all cases, sexual and social relationships strongly influence a bird's survival and breeding success. -
Download or read book Bewick s Swan written by Eileen Rees and published by A&C Black. This book was released on 2010-01-29 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fascinating and highly readable monograph, showcasing one of the flagship species of wetland conservation in Britain to superb effect. The arrival of thousands of Bewick's Swans from their Arctic breeding grounds to lakes and wetlands throughout northern and eastern Britain is an unforgettable sight. Popular among both birders and the wider public, these elegant birds are among the best-studied waterfowl in the world. Beginning with the work of the late Sir Peter Scott in the 1950s, Britain's Bewick's have been the subject of intensive behavioural study, while their population ecology has provided a similar focus for research. In Bewick's Swan, Eileen Rees tells the story of these birds in rich detail. Rees discusses their biology in full, with sections on population and distribution, breeding biology, wintering behaviour, food and feeding ecology, taxonomy and phylogeny, migration, and conservation; much original research is included, and there is frequent reference to the Bewick's sibling subspecies, the Tundra Swan of North America. Personal recollections from a lifetime of study weave through the narrative, which is illuminated by Dafila Scott's evocative illustrations.
Download or read book Aquatic Birds in the Trophic Web of Lakes written by Joseph J. Kerekes and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: Birds are an integral part of most freshwater ecosystems (lakes, rivers, wetlands) but their role in the trophic dynamics of these water bodies has often been overlooked. As a conspicuous part of the biota of water bodies, aquatic birds are indicators of their trophic state both in terms of species composition (quality) as well as occupancy and breeding (quantity). Birds may also influence the trophic state of a water body by importing nutrients (.e.g. resident or migrating birds feeding on adjacent watersheds or the sea). Because of anthropogenic activities, predation or their mobility, birds may not utilize otherwise suitable aquatic habitat. These factors complicate the relationship between aquatic bird production and the trophic status of habitats. As a consequence, the role of aquatic birds in freshwater ecosystems has usually been ignored. This volume contains a wide range of papers selected from those presented at the symposium and reviewed.
