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.

Point counts of buds are the most widely used quantitative method and involve an observer recording buds from a single point for a standardized time period. In response to the need for standardization of methods to monitor bird populations by census, various investigators met in Maryland in late fall 1991 to evaluate point counts. Their objectives were to present data from various investigations working under a wide variety of conditions, and to examine various aspects of point count methodology. This volume contains the papers given at the workshop, as well as a few additional relevant papers that subsequently have been submitted to the technical coordinators. Statistical aspects of sampling and analysis were discussed and applied to the objectives of point counts. From this base, at interactive sessions the participants discussed and agreed upon standards of point counts that should have wide applicability to a variety of habitats and terrain. The final chapter presents these standards and their applications to point count methodology. Forest Service, US Department of Agriculture

Minute-by-minute analysis of point counts of birds in mixed-conifer forests in the Sierra National Forest, central California, showed that cumulative counts of species and individuals increased in a curvilinear fashion but did not reach asymptotes after 10 minutes of counting. Comparison of the expected number of individuals counted per hour with various combinations of counting time and noncounting times for record keeping and travel between counting stations showed that 10-minute counts were most efficient in most cases. Counting longer than 10 minutes is not recommended, because other increased risk of double counting some individuals.

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.

Current widespread concern for the status of neotropical migratory birds has sparked interest in techniques for inventorying and monitoring populations of these and other birds in southeastern forest habitats. This guide gives detailed instructions for conducting point counts of birds. Presents a detailed methodology for the design and conduct of inventorial and monitoring surveys based on point counts, including discussion of sample size determination, distribution of counts among habitats, cooperation among neighboring land managers, vegetation sampling, standard data format, and other topics. This guide is a stand-alone text for managers interested in developing inventories of bird population on their lands. Charts and tables.
