Available in PDF, EPUB and Kindle. Book excerpt: Fall-migrating sandhill cranes arrived at congregation sites in southern Canada and in the States of the Central Flyway between late July and early October. Sandhills peaked at about 100,000 birds at way stations during the fall of 1964. Footprint measurements indicated that the lesser sandhill was by far the most numerous subspecies at way stations in Montana, North Dakota, South Dakota, and Colorado. These measurements also indicated that flocks stopping over in Wyoming, Kansas, and Oklahoma contained a significant number of Canadian sandhill or greater sandhill or both. A selective collecting program indicated that the footprint measurement technique overemphasized the incidence of the greater sandhill at way stations in North Dakota and South Dakota. Whooping cranes and sandhills were occasionally observed together during the early part of the fall migration. At times, fall-migrating sandhills fed on standing and harvested grain crops in Canada and the States of the Central Flyway, but seldom were depredations considered serious.

Available in PDF, EPUB and Kindle. Book excerpt: Lesser (Grus canadensis canadensis) and Canadian (G. c. rowani) sandhill cranes were studied from 1974 through 1977 in portions of the Central Flyway and Saskatchewan, Canada. The primary purposes of the study were to obtain estimates of (1) the lesser and Canadian sandhill crane populations during the fall and spring, (2) percent of juveniles in the population, and (3) hunting pressure, harvest, and crippling loss. Visual estimates of the numbers of cranes occurring within the main fall staging areas on the principal wintering grounds were made during periods of peak migration each October, and on the Platte River in Nebraska each spring. Feeding, roosting, and flying sandhill cranes were aged throughout the study area during fall and winter with the aid of binoculars and spotting scopes.

This book was released on 2005-01-24 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tension between wildlife protection under the Endangered Species Act and water management in the Platte River Basin has existed for more than 25 years. The Platte River provides important habitat for migratory and breeding birds, including three endangered or threatened species: the whooping crane, the northern Great Plains population of the piping plover, and the interior least tern. The leading factors attributed to the decline of the cranes are historical overhunting and widespread habitat destruction and, for the plovers and terns, human interference during nesting and the loss of riverine nesting sites in open sandy areas that have been replaced with woodlands, sand and gravel mines, housing, and roadways. Extensive damming has disrupted passage of the endangered pallid sturgeon and resulted in less suitable habitat conditions such as cooler stream flows, less turbid waters, and inconsistent flow regimes. Commercial harvesting, now illegal, also contributed to the decline of the sturgeon. Endangered and Threatened Species of the Platte River addresses the habitat requirements for these federally protected species. The book further examines the scientific aspects of the U.S. Fish and Wildlife Service's instream-flow recommendations and habitat suitability guidelines and assesses the science concerning the connections among the physical systems of the river as they relate to species' habitats.

Available in PDF, EPUB and Kindle. Book excerpt: Whooping Cranes: Biology and Conservation covers one of the most endangered birds in North America, and the subject of intense research and highly visible conservation activity. The volume summarizes current biological information on Whooping Cranes and provides the basis for future research necessary for conservation of this species. This edited volume concentrates on work completed in the past 20 years in the areas of population biology, behavior and social structure, habitat use, disease and health, captive breeding, and Whooping Crane conservation. Much of the information presented comes from the study and management of remnant and reintroduced populations of Whooping Cranes in the field; some information is from experimentation and breeding of captive Whooping Cranes. Whooping Cranes: Biology and Conservation seeks to inform and galvanize action dedicated to meeting the challenges faced by Whooping Crane managers and conservationists. Thus, it describes one model of endangered species conservation and restoration that will interest a wide audience: professionals that work on cranes; researchers in the fields of small population biology, endangered species, and avian ecology; wildlife veterinarians and those involved in avian husbandry; administrators of management agencies or conservation organizations; conservationists in other fields; teachers of conservation biology or ornithology and their students; and the educated general public. - Presents a comprehensive treatment of the biology and ecology of Whooping Cranes, including biology of both remnant and reintroduced populations of Whooping Cranes - Describes efforts over the past 45 years on conservation and the challenges of reintroducing an endangered species - Includes chapters from a variety of disciplinary and scale perspectives, ranging from evolution, to population ecology, behavior, habitat use, large landscape conservation, conflict, and conservation efforts - Features contributions that are readable, yet technically complete and fully referenced - Provides an example of partnership and collegial action that integrates information produced by scientific research and operational wildlife management - Edited and written by the leading Whooping Crane scholars and practitioners focused on this high-profile species of conservation concern
