Bats are fascinating in their variety and unusual way of life. These fierce-looking nocturnal mammals are noted for their ability to fly and feed in pitch-dark caves and on moonless nights, guided not by eyesight but by a highly developed sense - sonar. In addition to descriptions of major bat species from around the world, this book offers insights into such bat topics as feeding and hibernation, wing-shape and flight, and bat colonies. Eighty vivid full-color photographs portray the chracteristics and behavior of these unusual creatures.
