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.

This is a comprehensive historical record of all free-ranging bird species known to be breeding in Georgia around the beginning of the new millennium. The atlas profiles 182 species, from the sociable House Wren to the secretive Black Rail; from the thriving Red-shouldered Hawk to the threatened Wilson's Plover. The atlas is the result of a systematic survey conducted from 1994 to 2001, the massive collaborative effort of several private organizations, public agencies, and many individuals. It offers a wealth of information critical to bird-conservation efforts and provides a baseline so that changes to species ranges, numbers, and other significant aspects of each species' status can be better understood. Each species account includes: Color photograph of the bird Information on the bird's habitat and life history, distribution, population trends, and conservation status. Details discussed include diet, nesting habits, life cycle of the young, predators, and interactions with humans. Color distribution map showing the state's six ecoregions and indicating possible, probable, and confirmed breeding Graphs showing population trends, when appropriate Also included are chapters on the survey methodology, results of the surveys, influence of the physical environments of the state on bird distribution, changes in the avifauna since European settlement, and bird conservation.

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.

In 1974, the Massachusetts Audubon Society and the Massachusetts Division of Fisheries and Wildlife launched a five-year survey to map the distribution of all the birds that breed in the Commonwealth - the first such comprehensive effort in North America. Nearly 600 volunteers spent countless hours in the field collecting data. This landmark volume presents the results of their efforts. The book includes distribution maps showing possible, probable, and confirmed breeding areas for 198 Massachusetts nesting species on a grid of 989 tensquare-mile blocks. Opposite each species map is a summary account giving historical perspective, relative abundance, habitat, seasonal schedule, nest, egg, and song descriptions, clutch size, egg dates, number of broods, and other pertinent details. Each species account is illustrated with a scrupulously accurate, watercolor portrait by award-winning nature artists John Sill and Barry Van Dusen. The book also includes a set of six transparent overlay maps in an attached pocket that allow the reader to correlate key environmental factors with the distribution of nesting species. Introductory sections describe the atlas survey methodology, and two appe

The Second Atlas of Breeding Birds in West Virginia is the most comprehensive description of bird life in the Mountain State ever published. Building on the first Atlas, published in 1994, this book documents the occurrence of 170 species of breeding birds, including three new species and one whose last breeding record was in 1888. Compiled from the efforts of almost two hundred volunteers, who worked from 2009 to 2014 to amass more than one hundred thousand records and conduct point-count surveys, the Atlas presents detailed information about each species and two hybrids. Species accounts are accompanied by maps that show breeding evidence, as well as estimates of occurrence, change in occurrence, and population density. The volume covers state geography, climate, and changing habitats. It includes both a discussion of conservation concerns important to the state's breeding birds and a history of state ornithology and changes in West Virginia's avifauna drawn from observations and research from the nineteenth through the twenty-first century. Featuring up-to-date information about 170 bird species and hundreds of beautiful color photographs--nearly all of which are identified by county locations--The Second Atlas of Breeding Birds in West Virginia is an indispensable resource for researchers, conservationists, and birders.
