Animal Clocks and Compasses - 1960

"The fascinating, natural rhythms by which animals live and travel have puzzled scientists through the ages. They are continuing to search for the reasons and sometimes solve the puzzles in ways that are as interesting as animal habits themselves. What triggers bird migration and what points the way? Why does a woodchuck hibernate? The language of the bees, the journeys of whales, the migration of turtles, and the ways of many other creatures of the animal kingdom show an amazing sense of time and direction. Even human beings seem to have internal clocks. Will these clocks run more slowly when men travel in space at near the speed of light? There are many pieces to the puzzle of animal clocks and compasses, as Margaret Hyde excitingly shows. Science projects are included for those who want to experiment. Many detailed diagrams and illustrations complement the text..." - Animal Clocks and Compasses: From Animal Migration to Space Travel - Margaret O. Hyde. Illustrated by P.A.
