Book Description
This report on avian line-transect methods is provided as Section 6.3.2 of the US Army Corps of Engineers Wildlife Resources Management Manual. The report is designed to assist the District or project biologist in the application of line-transect methods to estimate the density and diversity of bird populations for planning, management, and research purposes. The basic line-transect survey involves walking a predetermined straight path and recording detections of birds along both sides of the line. The method is best suited to fairly large areas with homogeneous vegetation and gentle terrain, and can be used at any time of year. The report provides guidelines concerning transect establishment, sample size, survey timing and procedures, and interpretation of results, including an explanation and comparison of fixed width transects, Emlen's method, and a modified Emlen's method.

Pages : 276
Book Description
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.
