Children's LiteratureThe most striking feature of this short book is the full-color photography showing amazing images: the tiniest bats eating grapes or katydids, bats resting in a roost by the thousands and even millions, and mother bats finding their brand-new naked pups by their unique scent and squeak. In addition to chapters explaining the different types of bats, where and how they live and eat, and how they grow, there are chapters on the value of bats for controlling insects like mosquitoes or pests that damage crops. The concepts of "vulnerable," "endangered," "critically endangered," and "extinct" are explained, as well as the role of pesticides and pollution in placing many bats in the endangered category. Youngsters who might enjoy exploring caves are warned not to disturb hibernating bats with their flashlights or loud noises: "When bats are disturbed, they fly around looking for food and use up their stored energy. The bats can seldom find enough food in winter and many starve." Each volume in the "Earth's Endangered Animals" series includes Web resources, a glossary, and a very short, simple index, suitable for writing those very first short research papers. 2006, Crabtree Publishing, and Ages 4 to 8.
