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.

Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book Monitoring Bird Populations in Small Geographic Areas written by and published by . This book was released on 2006 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerous methods exist for monitoring bird populations, and there is a large literature describing them. There are few resources, however, that provide comprehensive advice on every step of organizing and carrying out a survey, from the early stages of planning to final use of the data. Even fewer resources are designed to meet the needs of a wide variety of potential users, from amateurs interested in change of bird life in a local study preserve to professionals testing hypotheses on the response of birds to habitat management, although much of the advice should be the same for every monitoring program. Whether survey objectives are very modest or rigorously scientific, samples must be sufficiently numerous and well distributed to provide meaningful results, and the survey should be well designed to ensure that the money and effort going into it are not wasted. This document is intended to be a complete resource for anyone planning to organize monitoring of noncolonial landbirds within a relatively small geographic area (e.g., from the size of a woodlot to a large park). The first of its two parts provides background explaining the importance of good study design and gives specific advice on all aspects of project planning and execution of high-quality data collection for the purpose of hypothesis testing. The second part is self-contained and nontechnical and describes complete plans for a site-specific checklist survey, suitable for addressing monitoring questions frequently asked by amateurs and for involvement of volunteers in data collection. Throughout are references to additional resources, from background literature to sources of existing survey protocols, analysis software, and tools for archiving data.

Available in PDF, EPUB and Kindle. Book excerpt: Presents a compilation of methods that can be used to assay population size, demographics, & status of virtually all species of landbirds in a wide variety of habitats. Suggests priorities for selecting a monitoring method & determining station location. Presents general tasks that determine which species can be monitored, & methods of establishing & maintaining a study plot, journal keeping, & training of personnel. Describes two demographic methods & four types of censuses for determining population size & trends. Methods are suggested for measuring habitat, recording weather, & color banding. Illustrated.

Download or read book Optimizing the Duration of Point Counts for Monitoring Trends in Bird Populations written by Jared Verner and published by . This book was released on 1988 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: "This volume covers all the major, broad-scale, multispecies monitoring programs in Canada aimed at tracking changes in species abundance. There are many other more local monitoring programs (e.g., tracking owls in Manitoba, the Red-shouldered Hawk Survey in Ontario, and game bird harvest surveys in many provinces) and a few national-scale surveys aimed at particular species (e.g., the Canadian Lakes Loon Survey), which are not covered in any detail here"--Introd.
Download or read book A Best Practice Guide for Wild Bird Monitoring Schemes written by Petr Voříšek and published by Ceska Spolecnost Ornitologicka Cso. This book was released on 2008 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarises recommendations on establishing, running andimproving national wild bird monitoring schemes. The methodologyis described in details and includes field methods, samplingdesign, data management and analysis, and communication; includingcase studies from various countries.The Best Practice Guide is not intended to replace existingtextbooks and methodological papers. The aim is to guidecoordinators of schemes in designing and running a scheme in orderto keep high methodological standards and avoid obvious mistakes.The book has nine chapters covering planning a scheme, surveydesign and selection of sample plots or field methods, it tacklesalso the problem of bird detectability and distance sampling, datamanagement and analysis, and principles and recommendations forusing the results for nature conservation and communication. Casestudies come from several European countries and cover subjectssuch as sampling design, field methods, working with volunteerfieldworkers, and setting up an on-line database. Finalrecommendations in a form of a list of 'things best to do' and'things best to avoid' are part of the publication too.

This book was released on 2015-02-13 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Guide is intended to provide guidance to field biologists wishing to analyze data collected onterrestrial bird populations, as part of an avianpopulation monitoring program. A second objectiveis to provide information that will help biologists design such programs. The audience is similar to that for the Handbook of Field Methods(Ralph etal.1993), the Monitoring Bird Populations by Point Counts(Ralph et al.1995), and in many ways this Statistical Guide to Data Analysis of Avian Monitoring Programscan be a useful complement to the field methods handbook. At the same time, we feel this Statistical Guide can be of use to field biologists studying other organisms besidesterrestrial birds. In our view, all field biologists will benefit from taking the equivalent of 2 or 3 semester courses in statistics and we assume thatreaders of this guide have completed at least this basic level in statistics
