A comprehensive survey of the valuable work undertaken by Britain's network of bird observatories, with summaries and tables of noteworthy events and much historical background. Bird observatories are research stations established mainly for the study of migration, particularly by means of ringing. There are now 18 scattered around the Britain and Ireland at key points on migration routes, on coastal promontories or small islands. Part of their attraction is the regular occurrence of rarities that are found each year at these observatories. Written by wardens and ringers from each location, Bird Observatories of Britain and Ireland is a timely new edition of one of the earliest Poyser titles. It includes detailed coverage of the history, location, habitats and ornithological interest of each observatory, including summaries and tables of noteworthy events.
Dr J.T.R. Sharrock is uniquely placed to write about the rare birds of Britain and Ireland. He is a member of all three bodies which adjudicate on such records - honorary secretary of the British Ornithologists' Union's Records Committee and a member of both the British Birds Rarities Committee and the Irish Records Panel. He is already the author of a companion book which deals with a selection of the commoner rarities, Scarce Migrant Birds in Britain and Ireland. In this new, much fuller book the enormous task of collation of over 8000 records and their visual display as maps and histograms was carried out by Mrs E. M. Sharrock. The textual and visual analysis deals with 221 different species. Between them, the authors present a complete picture of rare birds in Britain and Ireland: * HOW MANY are seen? * WHEN do they occur? * HOW regularly do they come? * WHERE are they seen? There are line drawings of all 221 species by well-known bird artists: Robert Gillmor, P. J. Grant, R. A. Richardson, D. I. M. Wallace and lan Willis. Jacket design by Robert Gillmor.
Scarce migrant birds of Britain and Ireland - how many are seen? How regularly do they come? Where do they occur? When are they likely to be spotted? The above questions are authoritatively answered by the author, Dr J. T. R. Sharrock, honorary secretary of the British Ornithologists' Union's Record Committee and of the Rare Breeding Birds Panel, joint convener of the European Ornithological Atlas Committee, and a member of the British Birds Rarities Committee and of the Irish Records Panel. Dr Sharrock takes a ten-year period and investigates in detail all the records of a selection of birds which occur here as scarce migrants - birds from Europe, from Asia and from America. He considers their breeding and wintering ranges, and the patterns of their records in Britain and Ireland, and tries to determine also - why do they visit us at all? Jacket design by Robert Gillmor.
This companion volume to The Atlas of Breeding Birds of Britain and Ireland is derived from surveys of birds present in Britain and Ireland during the three winters, 1981/82, 1982/83 and 1983/84. The surveys were organised by the British Trust for Ornithology and the Irish Wildbird Conservancy, as were the earlier breeding birds surveys. The Winter Atlas maps 200 species, 192 of which have full-page two-colour maps faced by a page of text. The texts (written by over 100 specialists) comment on the survey results, the species generally and the distribution and abundance as mapped. In addition there are introductory chapters on the maps, the weather in the three winters, bird patterns and movements; and appendices describing the planning, organisation, field methods, and processing of the survey data from record cards to computer output and maps. A team of 23 artists, led by Robert Gillmor, has provided the line drawings which head the species accounts.
In the year 1983, the British Trust for Ornithology celebrated its first 50 years. This volume records much of the history of birdwatching and ornithology since the early 1930s. The book is not a history of the BTO, but many of the Trust's achievements helped fashion the development and direction of ornithology over the decades, and major aspects of the Trust's work rightly have detailed treatment. The book ranges widely, it looks at the changing bird as well as the changing bird watcher and records the work of related conservation bodies, it considers the future and the past and includes an extensive section of useful facts and figures, whilst never losing sight of the central theme which is the book's title.
Living communities are continuously changing, both as a result of natural processes and of human activities. It is essential for us to have effective biological and ecological monitoring programs in order to detect these changes and understand the factors that influence them. In the first part of the book, the roles of local, national, and international organizations that implement monitoring programs are discussed and assessed. In the second section of the book, a wide range of examples are used to explain and evaluate methods of data collection, analysis, and interpretation. The final section focuses on the important applications of biological monitoring, such as pollution control, land-use management, monitoring rare species, and post-environmental impact assessment.
The Poyser avifaunas Birds in Scotland, Birds in Ireland and Birds in Wales are all now regarded as classic works. The series is now completed with Birds in England, an avifauna for England's diverse birdlife, past and present. England marks the northwestern limit for many Palearctic breeding birds, and is close to the southwestern limit for several others - in particular, several seabird species whose English colonies are of international significance. It is the first point of arrival for new colonists from the south - Little Egret and Yellow-legged Gull are two recent arrivals - and it is also of international importance for wintering and passage populations of various species which breed in the far north of the Palearctic. A diverse and fascinating avifauna is augmented by visits from an impressive range of rarities from as far afield as Siberia and Canada - Nearctic vagrants in particular are well-represented on the English list. This important new avifauna looks in detail at England and its birds, analysing present and historical data to present a complete picture of the status, range and abundance of every bird on the English list.
