From the author of "The Peregrine Falcon", this monograph presents a thorough summary of our knowledge of the species' natural history, emphasizing also the long association of the bird with humankind. Chapters cover distribution, feeding habits, social behaviour, movements, breeeding, territorialism and population regulation of ravens in Britain and Ireland. The author also looks at ravens and modern agricultural practice, their intelligence, and ravens elsewhere in the world.

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.
"Powerful illustrations complement writing of real insight into these formidable, yet playful, birds."

"Do buy this excellent book and read it."

"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."
"[Ratcliffe] presents a comprehensive and historical picture of this once common town scavenger."

"The personal approach by the author is refreshing and his administration for the raven is evident throughout the very readable text."
