Bat (a pipistrelle) wakes up, flies out into the night to eat, and returns home to feed her young. The narrative, in large type, gives much of the information about bats in a voice that can work as a read-aloud (“Gliding and fluttering back and forth, she shouts her torch of sound among the trees, listening for her supper”), while smaller type on some pages elaborates (“Using sound to find your way like this is called echolocation”). The watercolor-and-pencil illustrations, in browns and blues, hint of night, without being too dark. Close-up views of plants and animals show detail, while wider sweeping landscapes give context and a sense of space. The details of Bat’s fur and face do justice to this mammal, which many young kids may still think of as “gross.” This is useful as a very first introduction to bats, but readers will need to go farther to answer some questions (like what kinds of bats do eat “fruit, fish, frogs, even blood!”). And while there is an index of 15 terms, there is no bibliography. Nevertheless, this is a beautifully designed and thoughtfully executed informational storybook. (Picture book/nonfiction. 4-7)
