"Its very simple: We fear most what we understand the least."

"My trap consisted of two six-by-five aluminum frames with hundreds of vertical fishing lines strung between them. It looked like a harp, but with adjustable legs to support it a few feet off the ground and a canvas bag hanging below to hold captured bats. This device, which I had recently invented, was capable of catching thousands of bats per night, enabling me to sample and release large numbers without harming them."

"Bats are among the few true hibernators. The breathing of a hibernating bat is imperceptible. Its heartbeat drops from roughly 400 beats per minute when awake to about 25 in hibernation. The body temperature often falls to within a tenth of a degree of surrounding cave walls."

"More than 1,100 kinds of bats amount to approximately a quarter of all species, and they are found everywhere except in the most extreme desert and polar regions. Some 47 species live in the United States and Canada, but the majority inhabit s where, in total number of species, they sometimes outnumber all other mammals combined. Bats come in an amazing variety of sizes and appearances. The worlds smallest mammal, the of Thailand, weighs less than a , but some es of the Old World tropics have wingspans of up to 6 feet. The big-eyed, winsome expressions of flying foxes often surprise people who never have thought that a bat could be attractive."

"Populations of some North American insectivorous bats are known to have declined markedly in many areas over the past 20 years or more ... The causes and rates or extent of decline rarely are well documented."

"In s, cold winters force bats to migrate or . Most travel less than 300 s to find a suitable cave or abandoned mine, where they remain for up to six months or more, surviving solely on stored fat reserves. However, several species are long-distance migrators, traveling from as far north as Canada to the or Mexico for the winter. A few species can survive short-term exposures to subfreezing temperatures, enabling them to overwinter in cliff faces or in the outer walls of buildings."
