Book Description
A comprehensive monograph of the skua. Many birdwatchers may never have seen a skua; those who have will most probably have vivid memories of one or other species flying powerfully past a headland, or twisting and diving in pursuit of its piratical intentions towards a food-laden seabird - or, perhaps more memorably still, of themselves taking evasive action from the power-diving irate skua whose territory they have unwisely invaded. The full classification of the skuas is still debated, but Dr Furness of the Applied Ornithology Unit, Glasgow University, favours six species, of two genera, with five subspecies, based on current knowledge and his own long and dedicated field studies and research. All of the species are treated comparatively under the following chapter titles: Early history and classification, Distributions and populations, Migration patterns, Reversed sexual size dimorphism, Behaviour, Food and feeding, Kleptoparasitism, Plumage polymorphism, Breeding systems and social organisation, Breeding - laying to hatching, Breeding - hatching to fledging, Population dynamics, Pollutants, Skuas and agriculture, Skuas and conservation. The text is supported by 100 maps and diagrams, 30 photographs and 65 tables. In addition, John Busby contributes 35 evocative drawings which more than embellish this erudite and readable summary of an impressive and diverse group of birds. Jacket paintings by John Busby.

Book Description
Skuas (and jaegers) are a fascinating and popular group of seabirds that make up a subfamily of just seven species. They can be divided into two main groups: the larger species of Catharacta skuas which are mainly found in the southern hemisphere (with Great Skua breeding in the north), and the three Stercorarius species (also known as jaegers) which breed in the northern hemisphere. Both northern and southern skuas breed at high latitudes and several species are long-distance migrants, performing spectacular migrations through most of the world's oceans, sometimes even flying overland. The individual plumage variation in some species is enormous, creating one of the most puzzling yet fascinating challenges in modern field identification. This is the first complete identification guide to the skuas of the world. It is designed to enable species identification and correct ageing, and the information presented is based on years of study in the field, detailed examination of photographs and museum skins, and extensive research of the relevant literature. The comprehensive text is accompanied by twelve exquisite colour plates by Hans Larsson, illustrating a wide range of plumages. In addition, there are eight pages of colour photographs and numerous black and white photographs and drawings that show key identification features. With this book, the seabird enthusiast should at last be able to identify almost every skua encountered, whether on a seawatch or at sea.

Book Description
'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.

Book Description
This book is an essential reference for anybody who has watched birds in this amazing county. The County Avifaunas give full details of the status and range of every species recorded in the county in question. Each title covers all species on the county list, with a detailed breakdown of rarity records, and each has introductory sections describing the county's general ecology, climate, weather patterns, its ornithological history and conservation record. Essex is of national and international importance to many migrating and wintering wildfowl and waders, which can be found on the estuaries. Further inland, the Lea Valley harbours important populations of several species within the complex of reservoirs and gravel-pits. Elsewhere, the diverse habits of woodland and parkland, heaths and commons, agricultural land and urban areas mean that at all times of year there is the opportunity to see upwards of 100 species in a day with little effort. This book analyses and summarises all the data collated and documented over the last 200 years and includes available records to the end of 2004. Introductory chapters discuss the geology and habitats of Essex and the amazing fossil bird record. The individual accounts provide an up-to-date status of each species and patterns of occurrence within Essex. A distribution map is included for most breeding species. A breakdown and analysis are provided for all county rarities. Superb line drawings and photographs illustrate the book, all by talented local artists and photographers.
