The animal on the cover of sendmail Cookbook is a common European bat (Pipistrellus pipistrellus). Pipistrelles are the most common bat in Britain and are abundant throughout Europe and Asia, although they are reportedly endangered in Germany and Austria. Among the world’s smallest bats, Pipistrelles have a body length of 35 to 45 millimeters (about 1.5 inches) and a wingspan of 190 to 250 millimeters (about 9 inches). These tiny mammals have a voracious appetite, consuming up to 3,000 insects a night when the weather is warm. Averse to the cold, their behavior during winter months is mostly unknown. There has been a marked decline in the number of pipistrelles due to modern agricultural practices, including the use of insecticides and the illegal disturbance of their habitats by builders.
