The Summer Atlas of North American Birds by Jeff Price,Sam Droege,Amy Price Pdf
The North American Breeding Bird Survey comprises a network of regularly censussed, road-based survey routes and constitutes the most comprehensive set of data on the relative abundance and population trends of these birds during the summer months. Its value was highlighted in 1989, when the data were used to confirm suspected population declines in a number of species of neotropical migrants breeding in the northeastern United States and Canada. In this book Jeff and Amy Price and Sam Droege have used these data to create detailed, computer-generated maps showing the relative abundance of 450 species that summer in the contiguous United States and southern Canada. Tabular information on distribution hotspots for these, and a further 50 or so species too local in occurrence to map effectively, are also presented. As a data-based survey, the focus of the maps is on places where occurrence has been systematically confirmed over a number of years. As such, the maps provide a baseline for future and more regionally based studies. Supporting chapters provide details on the survey methodology, the mapping procedures used, and some current concerns in North American bird conservation.
Estimating Numbers of Terrestrial Birds by C. John Ralph,J. Michael Scott Pdf
This book was originally published in 1981 as a publication of the Cooper Ornithological Society and was based on the proceedings of a meeting of biologists and statisticians in Asilomar who gathered to examine the methods and assumptions used in estimating bird numbers. Counting birds has a long tradition. It is the currency of many ornithological studies. Bird counts have been seminal in our knowledge of bird migration, competition, ecology, population dynamics, environmental adaptation, impact of human alterations and island biogeography. Interest in estimating bird numbers remains high today but is often plagued by unasked or unanswered questions regarding sampling methods and treatment of the results. This book recorded the outcome of a meeting held to address these and other questions. It led to better understanding of what can and cannot be done with datasets. This volume remains a primary source of information on censusing of birds and other animals, and is frequently quoted in the primary literature of today. Since this volume went out of print some six years ago, demand has markedly increased for copies which are essentially unavailable, attesting to its currency today. C. John Ralph, received his Bachelors from the University of California, Berkeley and his doctorate from The Johns Hopkins University. Most of his early research was on bird migration and orientation. After a stint teaching at Dickinson College in Pennsylvania, he moved to Hawaii in 1976 where he began work on endangered forest birds for the Forest Service as a Research Ecologist. In 1981 he and his family moved to Arcata to join the Forest Service's Redwood Sciences Laboratory. One of his principal research topics there has been on an old-growth dependent bird, the Marbled Murrelet, involving extensive research from Alaska to California. His other principal work is on landbird monitoring, especially involving census and constant effort mist netting. Since 1994 he has directed research at a bird monitoring station in Costa Rica, now one of the longest running stations in Latin America. Beginning in 1980 he conducted research on an island off New Zealand involving monitoring and reintroduction of native birds. He has published more than 150 scientific articles and edited several books on bird monitoring and the Marbled Murrelet.
Ecology and Management of Neotropical Migratory Birds by Thomas E. Martin,Deborah M. Finch Pdf
The apparent decline in numbers among many species of migratory songbirds is a timely subject in conservation biology, particularly for ornithologists, ecologists, and wildlife managers. This book is an attempt to discuss the problem in full scope. It presents an ambitious, comprehensive assessment of the current status of neotropical migratory birds in the U.S., and the methods and strategies used to conserve migrant populations. Each chapter is an essay reviewing and assessing the trend from a different viewpoint, all written by leaders in the fields of ornithology, conservation, and population biology.
Survey Designs and Statistical Methods for the Estimation of Avian Population Trends by John R. Sauer,Sam Droege Pdf
Proceedings of a workshop on the analysis of avian population trends, held April 1988 in Laurel, Maryland. Describes the design of major avian surveys, presents major analytical methods used to estimate population trends, and provides analyses of scissor-tailed flycatcher data set.
The First Ten Years of the Co-operative Breeding Bird Survey in Canada by Anthony J. Erskine Pdf
1966-75 activities of the Breeding Bird Survey to detect and measure year-to-year and long-term changes in population of birds, particularly the smaller land birds.
Bird Census Techniques by Colin J. Bibby,Neil D. Burgess,David A. Hill Pdf
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.

Monitoring Bird Populations by Point Counts by C. John Ralph,John R. Sauer,Sam Droege Pdf
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.
