We know that animals cross miles of water land & sky with pinpoint precision on a daily basis. But it is only in recent years that scientists have learned how these astounding feats of navigation are actually accomplished. With colorful & thorough detail Natures Compass" explores the remarkable methods by which animals find their way both near home & around the globe. Noted biologist James Gould & popular science writer Carol Gould delve into the elegant strategies & fail-safe backup systems the invisible sensitivities & mysterious forces & incredible mental abilities used by familiar & rare species as they investigate a multitude of navigation strategies from the simple to the astonishing. The Goulds discuss how animals navigate without instruments & training at a level far beyond human talents. They explain how animals measure time & show how the fragile monarch butterfly employs an internal clock calendar compass & map to commence & measure the two-thous&-mile annual journey to Mexico
- all with a brain that weighs only a few thousandths of an ounce. They look at honey bees & how they rely on the sun & mental maps to locate landmarks such as nests & flowers. & they examine whether long-distance migrants such as the homing pigeon depend on a global positioning system to let them know where they are. Ultimately the authors ask if the disruption of migratory paths through habitat destruction & global warming is affecting & endangering animal species. Providing a comprehensive picture of animal navigation & migration " Natures Compass" decodes the mysteries of this extraordinary aspect of natural behavior."
