Book Description
The landscape of Britain has been irreversibly changed over the last century. Modern agriculture, urban expansion, industry and transport have all left their mark, altering the face of the countryside forever. Shifting with the changing scene, the fortunes of Britain and Ireland's bird populations have fluctuated dramatically over the years. As current farming practices have evolved, the natural habitats and breeding patterns of many species have been disrupted. Urban and industrial growth has brought with it the pressures of new land use, pesticides, pollution and human interference. The activities of sportsmen, collectors and farmers have also taken their toll over the years. The new Poyser title The Historical Atlas of Breeding Birds in Britain and Ireland 1875-1900 is a fascinating book resulting form years of meticulous research by the author, Simon Holloway, who provides an absorbing account of the distribution changes of Britain and Ireland's birds over the last quarter of a century. Large colour distribution maps and their accompanying text paint a species-by-species picture of a period which completely transformed the landscape of this country. It is, says Natural World magazine, "a classic case of 'why did no one write this book before?'...The experienced birder, using a knowledge of species requirements, can only marvel at what the long-vanished landscapes were then like." Birdwatch praises Simon Holloway's achievement, saying: "This book brings together so much information from disparate sources, and its status maps present such a clear picture of our late Victorian avifauna, that it should take its place beside the BTO atlases on the bookshelf." While Birdwatching adds: "If you are interested in the historical side of birds and their populations this book will be an endless source of fascination." As with all Poyser publications, the attention to detail, the lovingly produced illustrations and the sheer breadth of knowledge demonstrated by the autho

Book Description
The Raven presents a summary of knowledge of its natural history, describing its distribution, feeding habits, association with other animals, and breeding. The Raven is one of the most spectacular and romantic of British birds, but relatively neglected in the modern literature of ornithology. Derek Ratcliffe here presents a thorough summary of our knowledge of its natural history, emphasizing the long association of the bird with humankind. The place of the Raven in myth, legend and history is long established, and this book describes the bird's fall from grace as a valued scavenger in medieval cities to a persecuted outcast in the modern wilds. The previous wide occurrence of Ravens is reviewed against the relationships between their present distribution, status and habitat requirements, as both a nesting and a non-breeding resident. The dependence of Ravens on carrion (especially sheep) within an omnivorous diet is the key to the species' ecology, and its social behaviour has evolved in close relation to this lifestyle. The flocking and communal roosting of non-breeders are major features of Raven behaviour, while their nesting habits emphasise the territorial nature of breeding birds and their adaptation to secure but harsh environments. Raven numbers vary in relation to their food supply, local populations adjusting accordingly, although the precise mechanism involved is still obscure. Ravens have a considerable capacity for recolonising old haunts when suitable conditions are restored, as well as exploiting new areas where the habitat becomes favourable, and there are local success stories to tell. Nationwide, however, the species' position is delicately balanced and depends on both sympathetic land management practices and improving attitudes to Ravens as friends not foe. Worldwide, Ravens are one of the most successful of all bird groups, occurring over a large part of the northern hemisphere, and replaced in some southern and tropical regions by other raven species which exploit the familiar raven niche in their own environments. The discussion of the northern hemisphere species is enlivened by reference to other species where useful. Finally, the Raven's age-old reputation for high intelligence is weighed critically against the available evidence. Today, Ravens carry a new omen in the modern world, as a barometer of goodwill to wildlife. Like those in the Tower of London, the continued existence of Ravens in our wild countryside will reveal something about both our current situation and our prospects for the future. The text is brought to life through wonderful illustrations by Chris Rose.

Book Description
A comprehensive study of Pine Crossbills. 'From mid-January to mid-April 1935 I was off on my dilapidated bicycle, but how different Speyside was from Breckland. In late February many crossbills were still in flocks; I had to walk and cycle for many miles before finding my first nest in the last week of March, when I located a small breeding group in a plantation of old pines close to a keeper's cottage. Thenceforward, until 1942, I followed the crossbills and slowly began to understand a little about them. At first everything was gloriously new. I watched my crossbills mating and discovered how subtly a winter flock changed to a mating party and from a mating party to mated groups. I studied patterns of territory and dispersion and watched how hens built their nests. I sat under trees and I climbed to nests. I watched hens brooding and saw cocks feeding them. One hen pitched on my fingers and allowed me to catch her. I still vividly recall the sharp resiny scent of her body. I saw pairs rear their young and followed them and their broods through the forest. Soon my notebooks were full, but this was only the beginning.' That extract from the book's first chapter describes how the author began his study of the Scottish pine-feeding crossbills, having noticed earlier that the calls of crossbills in Rothiemurchus Forest were different from those of the spruce-feeding common crossbills he had known in the English Breckland. From this study and a quest for the true identity of the Speyside crossbills has emerged that all too rare book, a work of scholarship and research that is wholly readable, in which the author's delight in his study subject becomes the reader's, too.
