Book Description
The bats of the genus Myotis, though small and inconspicuous mammals, present many features of unusual interest from the point of view of systematic zoology. At nearly every point in its excessively wide range the genus is represented by several species often puzzlingly alike in superficial appearance though readily distinguishable from each other when the true differential characters are once recognized.

Book Description
There are more than 1,300 species of bats—or almost a quarter of the world’s mammal species. But before you shrink in fear from these furry “creatures of the night,” consider the bat’s fundamental role in our ecosystem. A single brown bat can eat several thousand insects in a night. Bats also pollinate and disperse the seeds for many of the plants we love, from bananas to mangoes and figs. Bats: A World of Science and Mystery presents these fascinating nocturnal creatures in a new light. Lush, full-color photographs portray bats in flight, feeding, and mating in views that show them in exceptional detail. The photos also take the reader into the roosts of bats, from caves and mines to the tents some bats build out of leaves. A comprehensive guide to what scientists know about the world of bats, the book begins with a look at bats’ origins and evolution. The book goes on to address a host of questions related to flight, diet, habitat, reproduction, and social structure: Why do some bats live alone and others in large colonies? When do bats reproduce and care for their young? How has the ability to fly—unique among mammals—influenced bats’ mating behavior? A chapter on biosonar, or echolocation, takes readers through the system of high-pitched calls bats emit to navigate and catch prey. More than half of the world’s bat species are either in decline or already considered endangered, and the book concludes with suggestions for what we can do to protect these species for future generations to benefit from and enjoy. From the tiny “bumblebee bat”—the world’s smallest mammal—to the Giant Golden-Crowned Flying Fox, whose wingspan exceeds five feet, A Battery of Bats presents a panoramic view of one of the world’s most fascinating yet least-understood species.

Book Description
With all new illustrations, color photographs, revised species accounts, updated maps, and a sturdy flexible binding, this new edition of the authoritative guide to bats in Texas will serve as the field guide and all-around reference of choice for amateur naturalists as well as mammalogists, wildlife biologists, and professional conservationists. Texas is home to all four families of bats that occur in the United States, including thirty-three species of these important yet increasingly threatened mammals. Although five species, each represented by a single specimen, may be regarded as vagrants, no other state has a bat fauna more diverse, from the state’s most common species, the Brazilian free-tailed bat, to the rare hairy-legged vampire. The introductory chapter of this new edition of Bats of Texas surveys bats in general—their appearance, distribution, classification, evolution, biology, and life history—and discusses public health and bat conservation. An updated account for each species follows, with pictures by an outstanding nature photographer, distribution maps, and a thorough bibliography. Bats of Texas also features revised and illustrated dichotomous keys accompanied by gracefully detailed line drawings to aid in identification. A list of specimens examined is located at batsoftexas.com.
