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

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.

Available in PDF, EPUB and Kindle. Book excerpt: This volume, the fourth in a series of books that collectively update and expand P.A. Johnsgard's 1975 The Waterfowl of North America, summarizes research findings on this economically and ecologically important group of waterfowl. The volume includes the mostly tropical perching duck tribe Cairinini, of which two species, the muscovy duck and the wood duck, are representatives. Both species are adapted for foraging on the water surface, mostly on plant materials, but typically perch in trees and nest in elevated tree cavities or other elevated recesses. This volume also includes the dabbling, or surface-feeding, duck tribe Anatini, a large assemblage of duck species that mainly forage on the water surface but nest on the ground, or only very rarely in elevated locations. Of this tribe, 12 species that regularly breed in North America are included, among them such familiar species as mallards, wigeons, pintails, and teal. Descriptive accounts of the distributions, populations, ecologies, social-sexual behaviors, and breeding biology of all these species are provided, together with distribution maps. Five additional Eurasian and West Indian species have been reported several times in North America; these have been included with more abbreviated accounts, but all 17 species are illustrated by drawings, photographs, or both. The text includes about 84,000 words and contains more than 1,000 references. There are also 12 distribution maps, 21 drawings, 28 photographic plates, and 58 anatomical or behavioral sketches.

Available in PDF, EPUB and Kindle. Book excerpt: Although the 12 species representing three waterfowl tribes described in this volume are not closely related, they fortuitously provide an instructive example of adaptive evolutionary radiation within the much larger waterfowl lineage (the family Anatidae), especially as to their divergent morphologies, life histories, and social behaviors. The whistling-ducks (Dendrocygna), with three known North American species, are notable for their permanent pair-bonds, extended biparental family care, and strong social cohesion. In contrast, males of the five typical pochards of North American diving ducks (Aythya) establish monogamous pair-bonds that are maintained only long enough to assure that the female's eggs are fertilized. The endpoint of this behavioral gradient, promiscuity or polygyny, exists among at least some of the typical stifftails (Oxyura). Such diverse reproductive strategies have exerted powerful evolutionary influences on interspecies variations in sexual dimorphism, sexual behavior, anatomy, ecology, and other traits. This volume includes more than 63,000 words, plus some 200 maps, photos, drawings, and sketches, and nearly 650 literature citations. It is the last of five volumes that describe all 55 waterfowl species that have been historically documented in North America; collectively, the volumes total over 300,000 words, with nearly 3,000 literature citations, and more than 600 maps, photos, drawings, and sketches.

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.
