With 150 of Henderson's exquisite close-up photographs of airborne birds, as well as diagrams illustrating the principles of flight and detailed information based on firsthand research, this book is as informative as it is simply delightful to look at.The singular beauty of an iridescent hummingbird pollinating a flower, the majesty of a condor soaring above the Andes, the impressive spectacle of migrating geese in Minnesota, black storks in Kenya, or Swainson's hawks in Bolivia:in your back yard or far afield, this guide lets you enjoy the beauty of birds taking wing while learning the fascinating science of how, precisely, birds fly.
