Bird Census Techniques [Anglais] [Relié]

"...relevant to ornithological field researchers, amateur and professional, and ecologists and conservation biologists undergoing census studies of wild bird populations."

"This guide to the various techniques used to count wild birds is relevant to ornithological field researchers, both amateur and professional, and ecologists and conservation biologists undergoing census studies of wild bird populations. The advantages, limitations and applications of each technique are discussed in detail."
—ETHOLOGY (January 2002)
"...an important and substantial update of an extremely valuable book. It is a 'must' for any bird-surveyors, volunteer and professional alike, who do not have the first edition--and probably also for those of you who do have."
—Juliet Vickery in BRITISH BIRDS (July 2001)

In this book there are entire chapters devoted to the most widely used bird counting techniques, and attempts to amalgamate other counting methodologies into major groups were made. Examples of the use of methods are provided wherever possible and the relative value of various approaches for answering specific questions is also addressed.

Key Features
* A newly revised edition of the immensely successful Bird Census Techniques
* An entirely new chapter covering the census methods recommended for tropical habitats
* Provides a concise guide to various census techniques and their opportunities and pitfalls

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 planning a census of birds in the wild should be able to select the method best suited to the study in hand, and to apply it to best effect within the limits inherent in it and the constraints of the particular study.
The first edition was immensely successful in setting the standard for sound bird census work in the 1990's. Here, four authors, each with their own relevant experience, have pooled their knowledge to produce this extensively revised second edition of Bird Census Techniques. An entirely new chapter covers the census methods recommended for tropical habitats with inhospitable field conditions and many species of birds, and all other chapters are updated to take account of recent developments in the field, in particular links between bird census studies and Environmental Impact Assessments.

Colin Bibby is Director of Science and Policy at the International Council for Bird Preservation where he is interested in the role of birds as indicators for global biodiversity conservation. While Head of Conservation Science at the Royal Society for the Protection of birds, he was a co-author of Red Data Birds in Britain. In both capacities, he has been struck by the small number of birds of conservation concern which have been counted adequately. He has counted birds in Britain and Europe, as a professional, as an amateur participant, and as an organizer of surveys for the British Trust for ornithology. He was motivated to start this book by the belief that bird-watchers would contribute more to conservation if they put more effort into counting birds, but lack of guidance on methods was a handicap.
