The Migration of Birds

Thomas Alfred Coward

Twice a year the birds cross continents, and T. A. Coward asks how and why. He explores the cause and origin of migration, the routes taken, and the astonishing height and speed of the great flights. Clear, curious, and full of wonder. A concise study of one of nature's most staggering feats. Look up as the flocks pass and understand the journey they are making.
