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. Today, Raven 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.

This 1977 book analyses and describes the range of variation in the wild flora and fauna of Britain and identifies important sites that exemplify this rich heritage. These key sites were chosen to represent all the main types of natural and semi-natural vegetation with their characteristic communities of plants and animals. The range of habitats, communities and species is classified under major formations, and in Volume 1, these are subdivided and described. The internationally applicable criteria for evaluating and selecting key sites are also fully discussed. Cambridge University Press published the Review on behalf of the Nature Conservancy Council and the Natural Environment Research Council. It will interest those concerned with the planning, management and use of land and water in relation to nature conservation, as well as for ecologists and naturalists.
