The animal on the cover of sendmail 8.13 Companion is a leaf-nosed bat, also known as the “New World” or “California” leaf-nosed bat. These bats are native to North America (Southern California, Arizona, and Nevada), Central America, and South America, as well as to parts of the Caribbean. They are so named because of a distinctive, “leaf-shaped” triangle that projects upward from their noses.

The leaf-nosed bat is nocturnal, rising late in the evening. It leaves its home to search for food, returns home after eating, then goes out again in the very early morning hours to repeat the cycle. It feeds on such things as insects, fruit, pollen, frogs, and spiders. This particular type of bat does not hibernate in the winter, nor does it migrate. It tends to become a bit more lethargic in cold weather, however. It prefers dry, desert climates, choosing to live mostly in caves and old abandoned mines. It lives in one of two social settings: either one male and many females, or all males who seek out females only in mating season, which occurs in early fall.
