explores bats and their fundamental role in our ecosystems through lavish full-color photographs and lively narrative. From the Giant Golden Crowned Flying Fox, a megabat with a wingspan of more than five feet, to the aptly named Bumblebee Bat, the world's smallest mammal, the number and diversity of bat species have proven to be both rich and underestimated. Nocturnal, fast-flying, and secretive, bats are difficult to observe and catalog. This richly illustrated handbook presents bats' evolution, biology, behavior, and ecology. It offers in-depth profiles of four hundred megabats and microbats and detailed summaries of all the species identified to date. Complete with an introduction exploring bats' natural history and their unique adaptations to life on the wing, includes close-up images of these animals' delicate and intricate forms and faces, each shaped by evolution to meet the demands of an extraordinarily specialized life.
