This is Thomas Alfred Coward's 1912's treatise, "The Migration of Birds". A fascinating and beautifully-written exploration of avian migratory patterns and habits, this is a volume not to be missed by modern readers with an interest in ornithology and nature writing. Thomas Alfred Coward (1867 - 1933), was an English ornithologist and astronomer who produced many books on natural history. Other notable works by this author include: "Bird and Other Nature Problems" (1931), "Bird Haunts and Nature Memories" (1922), and "The Birds of Cheshire" (1900). Contents include: "Migration Of Birds", "Cause And Origin Of Migration", "Routes", "The Height And Speed Of Migration Flight", "Orientation And Route Finding", "The Distances Travelled By Birds", "Migration And Weather", "The Perils Of Migration", "Early Ideas Of Migration", and "Suggestions And Guesses". Many vintage books such as this are becoming increasingly scarce and expensive. We are republishing this volume now in an affordable, modern, high-quality edition complete with a specially commissioned new biography of the author.
