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 Birds of the Yukon Territory written by Pamela H. Sinclair and published by UBC Press. This book was released on 2011-11-01 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Yukon is a land of remarkable wilderness, diverse ecosystems, and profound beauty. It is also home to a unique assemblage of birds. As of 2002, 288 bird species have been documented in the Yukon, with 223 occurring regularly. They occupy an amazing range of habitats, from the most barren mountain peaks to lush valley bottom forests, and are an integral part of the cultural heritage of Yukon First Nations people. The vast areas of natural habitat with limited road access can make the study of birds challenging, but are key in defining the nature of birding in the Yukon. Birds of the Yukon Territory is the result of a decade-long project initiated to gather and share what is known about the Yukon's birdlife. Lavishly illustrated with 600 colour photographs and 223 hand-drawn bird illustrations, the book presents a wealth of information on bird distribution, migration and breeding chronology, nesting behaviour, and habitat use, and on conservation concerns. Two hundred and eighty-eight species of birds are documented, including 223 regular species, and 65 casual and accidental species. In compiling this meticulously researched volume, the authors consulted over 166,000 records in a database created by the Canadian Wildlife Service, with information dating back to 1861. S ections on birds in Aboriginal culture and history, and bird names in the Yukon First Nations and Inuvialuit languages, enhance the book, as do the numerous easily interpreted charts and graphs. Destined to become a basic reference work on the avifauna of the North, Birds of the Yukon Territory is a must-have for bird enthusiasts and anyone interested in the natural history of the Yukon and the North.

Download or read book Wildlife of the Concho Valley written by Terry C. Maxwell and published by Texas A&M University Press. This book was released on 2013-09-01 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Concho Valley, named from the abundant mussel shells found in its principal river by seventeenth-century Spanish explorers, occupies a transitional position between the Chihuahuan Desert to the west and the Balcones Canyonlands to the east. As veteran field biologist and educator Terry C. Maxwell notes, the region has experienced wide-ranging changes in the makeup of its vertebrate populations, especially in the decades since farming and ranching began here in earnest, in the mid- to late 1800s. In Wildlife of the Concho Valley, Maxwell provides the first comprehensive summary of the animal life in this undercovered region of the state, which also happens to be his home territory. Uniquely qualified after a lifetime of study and field work, Maxwell places the region in its biogeographic context and then charts the history of vertebrate investigation there from the seventeenth century to the present. Following this ecological and historical perspective are accounts of all the fishes, amphibians, reptiles, birds, and mammals reliably known by zoologists and naturalists to have occurred in the Concho Valley over the past 150 years. The species accounts include Latin and English names; distribution and abundance status; remarks, where the author elaborates on habitat preference, behavior, and other aspects of natural history; specimens reported; and subspecies and synonyms. This important work of traditional natural history is liberally illustrated with Maxwell’s own drawings, photographs, and maps. An invaluable reference, Wildlife of the Concho Valley is a major contribution from one of the state’s most respected biologists and teachers.
