The National Zoological Park, as explored by Page, is a beautiful, eye-opening, and international experience. Page not only offers front-seat and behind-the-scenes tours of the zoo in Washington, D.C., he also covers animal preserves throughout the world. Page recounts how scientists and others from the Smithsonian have been working to return captive animals to natural habitats and ward off the extinction of tigers, elephants, and other endangered creatures. He keeps the scientific talk lively and entertaining at all times supplementing his text by 200 wonderful color photographs of animals in action. The illustrations will certainly enchant animal lovers, but all readers should appreciate this perspective on a zoo as an active force in wildlife conservation.
