Amadon D. Birds around the World: a Geographical look at Evolution and Birds
Garden City, NY: The Natural History Press, 1966. — 176 p.
There are almost 9,000 species of birds, each with its own particular range. One species mav be found throughout the entire Pacific, another related species may be found on only a single island. The richness and diversity of birds has been not only a source of great pleasure for millions but a source of curiosity for the naturalist.
In this book, a well-known ornithologist takes the reader on a tour of the world of birds. He delves into the geological past when the first birds were taking to the air; he examines the history of bird extinction and the continuing process of evolution and speciation.
From the dramatic migration of seabirds over thousands of miles, to the gradual extension of the range of a song bird over a few miles, this book explores the many facets of the distribution of birds.
