Scientists probe eleven animal mysteries. Why do some parrots eat clay? Which elephants are the wisest? Is the platypus a bird, a mammal, or something else? In this collection of science articles from Highlights for Children magazine, teams of researchers travel the world to solve some of nature's most intriguing puzzles. One team uses a high-tech camera to find polar bear dens under the snows of Alaska. Another group teaches dolphins how to play a game in order to study their sonar. Still other teams spend years studying elephants, crows, wild horses, rattlesnakes, cliff swallows, and other animals. Full-color illustrations bring these fascinating animals to life, and Jack Myers, in his warm, personal style, re-creates the scientists' adventures in discovery. His stories are true cases of science in action--the challenging and often creative process of revealing nature's secrets. He will start young readers thinking about the many secrets that still wait to be discovered . . . maybe by them.
