Book excerpt: The National Audubon Society's annual Christmas Bird Count stars in this charming picture book, just right for young community scientists, bird watchers, and nature aficionados. A young girl and her mother participate as community scientists in the Christmas Bird Count. The girl is excited when Big Al, the leader of their team, asks her to record the tally this year. Using her most important tools―her eyes and ears―she eagerly identifies and counts the birds they observe on their assigned route around town. She and her team follow the rules, noting the time of day, the habitat, the birding ID techniques used for each sighting. Finally, they meet up with the other teams in the area to combine their totals for a Christmas Bird Count party and share stories about their observations. Sidebars tally up the birds they observe and record. This book introduces young readers to birdwatching with simple explanations of birdwatching techniques and clear descriptions of bird habitats. Stephanie Fizer Coleman's charming illustrations add color and context to a joyful story that's sure to inspire the nature lover in everyone. Back matter includes more information about all the birds featured in the book and about the Christmas Bird Count, the nation's longest-running community science bird project.

Download or read book Bird Census Techniques written by Colin J. Bibby and published by Academic Press. This book was released on 2012-12-02 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wild birds are counted for a wide variety of reasons and by a bewildering array of methods. However, detailed descriptions of the techniques used and the rationale adopted are scattered in the literature, and the newcomer to bird census work or the experienced bird counter in search of a wider view, may well have difficulty in coming to grips with the subject as a whole. While not an end in itself, numerical and distributional census work is a fundamental part of many scientific and conservation studies, and one in which the application of given standards is vital if results are not to be distorted or applied in a misleading way. This book provides a concise guide to the various census techniques and to the opportunities and pitfalls which each entails. The common methods are described in detail, and illustrated through an abundance of diagrams showing examples of actual and theoretical census studies. Anyone with a bird census job to plan should be able to select the method best suited to the study at hand, and to apply it to best effect within the limits inherent in it and the constraints of the particular study. The Royal Society for the Protection of Birds and the British Trust for Ornithology have for many years pioneered the collaboration of amateurs and professionals in various census studies. Three members of their staff, each with extensive field experience, now pool the knowledge of these investigations to lay the groundwork for sound census work in future years.
Download or read book Monitoring Bird Populations by Point Counts written by C. John Ralph and published by DIANE Publishing. This book was released on 1998-05 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Point counts of birds are the most widely used quantitative method and involve an observer recording birds from a single point for a standardized time period. In response to the need for standardization of methods to monitor bird populations by census, researchers met to present data from various investigations working under a wide variety of conditions, and to examine various aspects of point count methodology. Statistical aspects of sampling and analysis were discussed and applied to the objectives of point counts. The final chapter presents these standards and their applications to point count methodology.

Download or read book Twelve Hundred Miles by Horse and Burro written by Harley Shaw and published by University of Arizona Press. This book was released on 2022-05-31 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: J. Stokley Ligon's work in bird conservation, habitat protection, and wildlife legislation during the mid-twentieth century is well-documented in his own writing and the writing of others. But hovering in the background of Ligon's life story has always been the rumor of a trip he made alone as a young man in 1913 in which he covered much of New Mexico alone on horseback. Details of the trip had faded into history, and Ligon—a self-effacing man—had never published the story. As it turns out, the trek was Ligon's first job with the US Biological Survey, and it did not go entirely undocumented. The breeding bird population report that eventually resulted from the journey, photographs from glass plate negatives, and—perhaps most enticingly—Ligon's own personal diary from these travels are presented here. Not just a compelling account of the expedition itself, the materials and insights found in this volume also reveal aspects of Ligon's family history, his early interest in wildlife, and the development of the wilderness skills needed to undertake such a survey. Using his original itinerary and handwritten report, the authors of this book revisited many of the places that Ligon surveyed and in a few cases were even able to locate and repeat Ligon's early photographs. Combined with a discussion of the conditions of birds and other wildlife then and now, this volume serves as a useful tool for understanding how wildlife numbers, distribution, and habitats changed in New Mexico over the course of the twentieth century. Birding enthusiasts, historians, naturalists, and even armchair adventurers will all find something to love in this chronicle of a young man from a West Texas ranching family with a driving ambition to be a professional naturalist and writer.
