Poyser Monographs - Böcker

For this third edition, the typematter has been reset throughout to accommodate the many revisions and additions to the text. The identification drawings, too, have been reviewed and lan Willis has amended or redrawn elements of most of the Figures and has provided several additional drawings. There are 70 new photographs in the section of plates which has now been increased to 96 pages with a total of 248 photographs. The identification of the diurnal birds of prey is especially difficult. There is wide variation in plumage among some species, especially the eagles and buzzards, and in all species general outlines and wing positions are much affected by the prevailing conditions, by wind and light, and by the bird's behaviour at the time. Often, too, the birds are only sighted at long range, and the authors believe that when travelling extensively in Europe even the expert cannot hope to identify more than seventy per cent of the raptors seen. In the book, the 38 European species have been grouped into seven sections. Each section brings together those species with similar field characters between which confusion can so often, and so easily, arise. Each group has an introductory comparative text and drawings, and the species within the groups are then treated individually. The text, succinct and detailed as it is, is greatly enhanced by lan Willis's fine drawings, and there are 248 photographs especially chosen to illustrate aspects of identification. The book has a final section summarising the legal status of birds of prey in European countries. Jacket drawings are by Ian Willis

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 foes. 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.

The Nuthatches is based on the European Nuthatch, with comparative information on the other west Paleartic and world species.The nuthatches are common and widespread birds throughout the Northern Hemisphere, but only poorly studied until quite recently. Erik Matthysen's extensive studies, started in 1982, have done much to illuminate the ecology of the Eurasian species, and to create a rich picture both of this bird and its 23 fellows around the world.The nuthatches are familiar for their peculiar, head-down, foraging style on the trunks of mature woodland trees. They are also noteworthy for their generally elaborate nest building behaviour - ten of the nuthatch species use mud to reduce the nest cavity entrance Ca behaviour otherwise shown only by hornbills) while others make elaborate constructs entirely of mud, or use resin to repel nest predators.They also exhibit a complex territorial system and associated behavioural repertoire, occupying a territory as a pair, year round, perhaps as an adaptation to their reliance on stored food during the winter months. The intricate dynamics of pair-bond stability, territory size and the various strategies of floating, non-territory holders is the subject of an entire and fascinating chapter.The habitat fragmentation that has accompanied widespread disruption of woodland habitats everywhere has had a profound effect on territorial and social behaviour and this too is dealt with at length. Following a detailed description of the ecology and behaviour of the Eurasian Nuthatch, Erik Matthysen goes on to consider what is known of the other species, and to compare and contrast their biology.Although many are poorly known, this part of the book enables many fascinating insights and sets the scene for further work which may explain the links between the ecology, behaviour, habitat and evolutionary relationships of the various species. David Quinn' s excellent drawings complete an interesting and authoritative volume.

This text presents the tundra plovers, comprising of the grey plover and the Eurasian, Pacific, and American golden plovers. Breeding on tundra or northern heaths and moorland, they migrate far south to coastal mudflats, saltings and agricultural landscapes. The text examines the taxonomy, appearance, behaviour, ecology and conservation of golden and grey plovers, and compares and contrasts their natural history and biogeography. It also gives accounts on all aspects of their lifestyle including feeding, mating, parental care, moults, migration and avoidance of predators.
