Bird Migration - A General Survey

The question of how birds migrate over enormous distances with apparently minimal guidance continues to excite both professional and amateur ornithologists. Nearly ten years have elapsed since Peter Berthold a leading researcher in the field wrote the first edition of this highly readable and fascinating book. During that time the field has advanced by strides so that this new edition has been extensively revised expanded and updated. No other book exists that brings together the vast amount of information that is available on the subject of bird migration so that the book will be an inspiration to birdwatchers naturalists and ornithologists alike.
