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.Richard J. Barker and John R. Sauer2 Abstract: The dominant feature of point counts is that they do not census birds, but instead ... Considering a simple model for point count sampling, we demonstrate that use of these incomplete counts can bias ... In this paper we develop a model for point count sampling and consider how incomplete counting affects some of the ... process, we consider only the binomial model, which is conceptually easy to understand in the point count context.
