Available in PDF, EPUB and Kindle. Book excerpt: As part of a program to characterize the plant and animal life of the Laboratory site and the surrounding region, the two breeding bird censuses originated in 1977 were continued in 1979. Twelve census trips were made to the BNL plot and 10 to the Westhampton plot by seven volunteer observers. Comparisons of data from the three years showed that the number of territorial males on the BNL plot did not change significantly, but the number of breeding species showed a continuous decline, from 18 to 10. Little change in the number of territorial males or in species composition occurred in the Westhampton plot.

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.

Download or read book Birds in Scotland written by Valerie M. Thom and published by A&C Black. This book was released on 2010-11-30 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'The most important work on the birds of Scotland ever published' - British Birds This comprehensive study and review of the birds in Scotland follows on from where the celebrated two volumes of The Birds of Scotland (1953), by Dr Baxter and Miss Rintoul, left off. It does more than that, however, since not only has there been a profound increase in ornithological coverage and data (as reflected in the species accounts), there have also been great changes in habitat and environment since the days of Baxter & Rintoul. These aspects form the themes of the ten preliminary chapters reviewing the Scottish scene today in terms of habitat, conservation, birdwatching and the changes in species status and distribution. The species accounts, the backbone of the book, review the period 1950-83 but include, where practicable, records of rarities and details of counts up to the spring of 1985; there are also brief summaries of earlier data based on the researches of Baxter & Rintoul. In all, 497 species are dealt with. The texts of major species accounts are complemented by 173 distribution maps and many tables of relevant data, and there are 129 species drawings by a team of artists under the editorship of Donald Watson, who also contributes chapter head pieces and other drawings. A section of photographs illustrates the varied habitats typical of Scotland today. There are, further, appendices and an extensive bibliography. The book will be of great interest to all birdwatchers in Scotland but of special value, too, to the many thousands of birdwatching visitors from elsewhere in these islands and from countries abroad. The Scottish Ornithologists' Club, for whom the book is published, and all whose records and researches made the author's work possible, have reason to be proud of Valerie Thom's achievement.

Available in PDF, EPUB and Kindle. Book excerpt: It is not often that a century of scholarly activity breaks conveniently into halves, but ornithology of the first half of the 20th century is clearly different from that of the second half. The break actually can be marked in 1949, with the appearance of Meyer and Schuz's Ornithologie ais Biologische Wissenschaft. Prior to this, ornithologists had tended to speak mostly to other ornithologists, experiments (the testing of hy potheses) were uncommon, and a concern for birds as birds was the dominant thread in our thinking. Subsequent to 1949, ornithologists have tended to become ever more professional in their pursuits and to incorporate protocols of experimental biology into their work; more importantly perhaps, they have begun to show a concern for birds as agencies for the study of biology. Many of the most satisfying of recent ornithological studies have come from reductionist research ap proaches, and have been accomplished by specialists in such areas as biochemistry, ethology, genetics, and ecology. A great many studies routinely rely on statistical hypothesis testing, allowing us to come to conclusions unmarred by wishful thinking. Some of us are ready to tell the world that we are a "hard" science, and perhaps that time is not so very far off for most of us. Volume 2 examines several solid examples of late 20th-century ornithology.

Download or read book Birds in Ireland written by Clive Hutchinson and published by A&C Black. This book was released on 2010-09-30 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Birdwatching has become an increasingly popular pastime in Ireland as elsewhere. Nor is all of the birdwatching done by the Irish. Many professional ornithologists from Britain and Western Europe find good reason to study Ireland's birds, as do the numerous birdwatching visitors each year. Clive Hutchinson, a leading Irish ornithologist, has compiled this comprehensive review of birds in the Republic and Northern Ireland to coincide with the 21st anniversary year of the Irish Wildbird Conservancy's foundation and he has had the IWC's active support throughout. The book is timely for other reasons, too. Knowledge about the status and distribution of birds in Ireland has increased greatly since the 1960s and this is reflected in the detailed species accounts which form the major part of the book. Factors which led to this greater knowledge, recent changes in bird distribution and status, and reasons for the absence of some species are topics discussed in the book's introductory chapters. Other subjects covered are Ireland's topography, climate and habitats, a review of ornithology and ornithologists in Ireland over the last 100 years, and conservation programmes of more recent times. John Busby's superb illustrations (more than 100) are a feature of the book, helping to set the Irish scene as well as its birds. Jacket paintings by John Busby
