An overview of the history and ornithological significance of the Bird Observatories of Britain.

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?

A detailed and up to date assessment of the status and distribution of every species of bird in Britain and Ireland.

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.
