Amazing Speed-flash Kodachrome Close-ups of Wild Birds, Undisturbed in Their Natural Habitat « TALKING BIRDS WITH COLOR CAMERA" brings you an entirely new close-up of wild bird life. This natural history treasure is the first book on birds to be profusely illustrated with NATURAL-COLOR photographs-many in full-page size! Most of them were taken from concealment within arm's reach of the wild subjects-flying, brooding on the nest, and feeding their young. Beautiful beyond comparison, this book is a result of 50 years of distinguished ornithological achieve ments by Dr. Arthur A. Allen. His notable re search and field expeditions, sponsored in great part by the National Geographic Society, have added immeasurably to North American bird lore. Publication of this volume, edited by Dr. Gilbert Grosvenor, adds another important contribution of The Society to its educational purposes-the in crease and diffusion of geographic knowledge. Many of the 331 NATURAL-COLOR photographs are high-speed flash pictures, such as 1/5000-second Kodachromes which "freeze" the vibrating blur of hummingbirds' wings.
