Beskrivning

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.

Mer om författaren

Derek Ratcliffe grew up in Carlisle and began watching Ravens in the Lakeland fells while still a schoolboy. He later explored the Southern Uplands, Snowdonia and the Highlands, and developed a particular enthusiasm for the wildlife of the mountains and moorlands. In 1956, he joined the staff of the Nature Conservancy in Scotland, and worked for several years on the survey of vegetation in the Scottish Highlands and Islands. After this, Derek became involved in monitoring of the British Peregrine population and in the Monks Wood studies of the effects of organochlorine insecticides on birds of prey. In the late 1960s, he was responsible for the compilation of A Nature Conservation Review, an inventory of the most important terrestrial and freshwater sites in Britain for biological conservation. When the Nature Conservancy was set up anew in 1974, he became Chief Scientist and remained in his post until retirement in 1989. Although Ravens have always had to be largely a spare-time interest, he has managed to be in their nesting haunts in the spring of every year from 1945 onwards, and continues to enlarge his knowledge of their ways in the company of fellow Raven enthusiasts. He enjoys the freedom of retirement to pursue field work and to write about wildlife and its conservation.Chris Rose is an internationally acclaimed wildlife artist who specialises in wildlife within the landscape.

Recensioner i media

It is the sort of bird book I particularly enjoy because a fresh wind blows through much of it, showing the author to be what a writer about ravens should be--an acute observer. Guardian Powerful illustrations complement writing of real insight into these formidable, yet playful, birds. New Scientist Do buy this excellent book and read it. Cambrian Ornithology Society Bulletin No 112 Derek Ratcliffe has an enthusiasm that shines through the pages of his latest book. The text is supported by extensive appendices and tables, crammed with data and facts; serious matters of behaviour and ecology are addressed; but the presentation is constantly enlivened by anecdote. This is a book about real birds, not textbook abstractions. As such it is a joy to read as well as a valuable contribution to ornithology. Habitat [Ratcliffe] presents a comprehensive and historical picture of this once common town scavenger. Birding World The personal approach by the author is refreshing and his administration for the raven is evident throughout the very readable text. hland News Group
