Book Synopsis The North American Swans: Their Biology and Conservation by : Paul Johnsgard
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.

Book excerpt: This book is a compendium of short stories and excerpts of personal journal entries from the life of Jack Whitman, a wildlife biologist who spent fifty years in some of the wildest places that remain on this earth. It is about his love of those places and the wild inhabitants with which he shared those lands. It is about a deep devotion towards understanding the ecology of predators and their prey, and with that knowledge, greater respect and better management of those natural resources. It is about his gratitude for living modestly and pushing life to the limits. It will make you laugh. It will make you cry.

Book Synopsis Trumpeter Swan Survey of the Rocky Mountain Population by : James A. Dubovsky
Download or read book Trumpeter Swan Survey of the Rocky Mountain Population written by James A. Dubovsky and published by Createspace Independent Pub. This book was released on 2012-08-17 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Rocky Mountain Population (RMP) of trumpeter swans (Cygnus buccinator) consists of birds that nest primarily from western Canada southward to Nevada and Wyoming. The population is comprised of several flocks that nest in different portions of the overall range. The RMP/Canadian Flocks consist of birds that summer primarily in southeastern Yukon Territory, southwestern Northwest Territories, northeastern British Columbia, Alberta, and western Saskatchewan. The Tri-state Area Flocks summer in areas at the juncture of the boundaries of Montana, Wyoming, and Idaho (hereafter termed the tri-state area) and nearby areas. The RMP/Canadian and Tri-state Area flocks winter sympatrically primarily in the tri-state area. In addition, efforts have been made to establish several restoration flocks, such as those at Ruby Lake National Wildlife Refuge (NWR) in Nevada (i.e., Nevada flock) and those at Malheur NWR and Summer Lake Wildlife Management Area (WMA) and vicinity (i.e., Oregon flock), by translocating adult swans and cygnets from other portions of the RMP. These birds tend to winter in areas near those where they nest. This report contains information only from the Tri-state Area and restoration flocks, collectively referred to as the RMP/U.S. Breeding Segment. These terms for the various groups of swans are consistent with the RMP Trumpeter Swan Implementation Plan (Pacific Flyway Study Committee 2002). The Fall Trumpeter Swan Survey is conducted annually in September. The survey is conducted cooperatively by several administrative entities and is intended to provide an accurate count of the number of RMP trumpeter swans that summer in the U.S. The history of the survey dates back to the 1930s, although methods and survey coverage have changed over time as the number of swans increased and new technologies became available. Survey methodology and coverage have remained fairly consistent since 1966 (D. Olson, pers. comm.). To be consistent with previous reports, only the data from 1967 to present were analyzed for this report. The data are used by managers to assess the annual status of the Tri-state Area Flocks and restoration flocks. Observers counted 371 swans (white birds and cygnets) in the U.S. Breeding Segment of the Rocky Mountain Population of trumpeter swans during fall of 2002, a decrease from 475 counted from comparable areas last year and the lowest count since 1993. The number of white birds (311) declined 23% from that of last year, while the number of cygnets (60) decreased by 15%. Declines occurred in all 3 states in which the Tri-state Area Flocks nest, and was greatest in Montana (-37%). Decreases in Idaho and Wyoming were 20% and 8%, respectively. The number of birds in restoration flocks also decreased 17% compared to the count from last year. The count for the Tri-state Area Flocks this year was a marked departure from their recent upward trend in numbers. The tri-state area continues to experience drought conditions, with Palmer Drought Index values the lowest recorded since surveys were initiated in the 1930s.

Book Synopsis Birds of the Yukon Territory by : Pamela H. Sinclair
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.
