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 Swans: Their Biology and Natural History Book in PDF, ePub and Kindle
The seven species of swans are an easily and universally recognized group of waterfowl, which have historically played important roles in the folklore, myths and legends in many cultures. Among the largest of all flying birds, they have been used as symbols of royalty, grace and beauty, and largely for these reasons swans have only rarely been considered acceptable as targets for sport hunting. Swans occur on all continents but Africa, though most species are found in the temperate and arctic zones of North America and Eurasia. Swans are a long-lived species and are among the most strongly monogamous of birds, having prolonged pair and family bonds that influence their flocking and social behavior, and contribute to the overall high degree of human interest in them. This volume describes their distributions, ecology, social behavior, and breeding biology. Included are nine distribution maps, 19 drawings, 23 photographs by the author, and a bibliography of nearly 700 references.

Download Bewick's Swan Book in PDF, ePub and Kindle
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.
