Originally published during the early part of the twentieth century, the Cambridge Manuals of Science and Literature were designed to provide concise introductions to a broad range of topics. They were written by experts for the general reader and combined a comprehensive approach to knowledge with an emphasis on accessibility. The Migration of Birds by T. A. Coward was first published in 1912 and reissued as this third edition in 1929. The volume presents an account of the migratory habits of birds, containing established observations as well as some speculative suggestions regarding potential discoveries.
