Available in PDF, EPUB and Kindle. Book excerpt: By the early 1930's, the United States' population of trumpeter swans (Olor buccinator Richardson) had been reduced to a meager few. The 1932 Swan Census by the Bureau of Sports Fisheries and Wildlife and the National Park Service showed only 69 in the United States. Through protection and the establishment of Red Rock Lakes Wildlife Refuge by the Bureau of Sport Fisheries and Wildlife, the population has increased to near 1000 so that the species is no longer classified as endangered. Early efforts were mainly to protect and assure the birds privacy while the population grew. When numbers indicated a recover from near extinction, efforts were made to study the birds. In 1960, Winston Banko published the results of several years' work at Red Rock Refuge. He compared his and other authors' work in such areas as the distribution and status of trumpeters, their habitat, life cycle, population, and management. He concluded that trumpeter swans in the tri-state region of Montana, Idaho, and Wyoming should no longer be considered an endangered species since the population showed signs of leveling off at a maximum level. He also concluded that the rate of population change was tied to the productivity of mated pairs, and that both were inversely proportional to population density. Since the rate of increase approached zero about 1954, Banko assumed that at that time the populaiton had reached the maximum level the environment would support.

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.

Kortright and later revised by Frank Bellrose, this latest edition, which has been meticulously updated by renowned waterfowl biologist Guy Baldassarre, continues the legacy of esteemed authors. Each species account contains in-depth sections on: • identification • distribution • migration behavior • habitat • population status • breeding biology • rearing of young • recruitment and survival • food habits and feeding ecology • molts and plumages • conservation and management To facilitate identification, the species accounts also include detailed illustrations of wings. An appendix contains comparative illustrations of ducklings, goslings, and cygnets. This edition of Ducks, Geese, and Swans consists of two volumes, printed in full color, and packaged in a slipcase, along with a CD containing references and additional maps.
